!Geography and Climate
164
Aragats Research Station is located on Mt. Aragats, a dormant stratovolcano in central Armenia, approximately 50 km (30 mi) northwest of Yerevan, Armenia. The youngest lava flows date between the late-Pleistocene and 3000 BCE (Kharakanian et al., 2003). As such, the station is located on solid volcanic rock foundations. At 3200m a.s.l., the Aragats Research Station lies above the tree line, on the shore of the man-made Lake Kari. [br]
166
At the Aragats Research Station, the average winter temperature is around -15 °C (5 °F), with temperatures occasionally reaching as low as -40 °C (-40 °F); during the summer, the average temperature is 12 °C (54 °F), with highs up to 20 °C (85 °F). Throughout the year, the humidity is between 72% and 80%. Average winds range from 20 km/hr (10 mph) in the summer to 40 km/h (20 mph) in winter, with occasional gusts up to 150 km/h (90 mph). For around 250 days each year, 1.65m of snow covers the ground.[br]
170
The Aragats Research Station has everything necessary of year-round operation. Mains power is available to the station, with diesel generators waiting on stand-by in case of loss of power. Detectors and their electronics are supported by servers and network connections to Yerevan. Staff spend one month shifts at the station; they have conference rooms, heated dormitories and a restaurant at their disposal.

The [b]Ar[/b]agats [b]N[/b]eutron [b]M[/b]onitor ([b]ArNM[/b]) has been in operation at [[Aragats Research Station]] since 2000. The ArNM based on the 18-tube [url="http://www.nmdb.eu/?q=node/142"]NM64 neutron monitor[/url] design. The 18 counter tubes are filled with [sup]10[/sup]B-enriched boron-trifluoride (BF[sub]3[/sub]) gas, and detect neutrons by the ionization of the gas resulting from the exothermic reaction of the neutron and [sup]10[/sup]B to produce [sup]7[/sup]Li and [sup]4[/sup]He. In order to increase the efficiency of the ArNM, incoming particles are moderated by 6cm of polyethylene. The tubes themselves wrapped in lead to enhance the count rate by the [sup]210[/sup]Pb(n,2n) reaction, followed by another layer of polyethylene moderator 2cm thick. [br]
231
The monitor electronics provide time integration of counts for three dead times. The first dead time is 400ns, which collects almost all secondary neutrons generated in the lead producer of the ArNM. The second and third dead times are 0.25ms and 1.25ms (as with most of the NM64 world-wide network).

!Lightning Detector Boltek StormTracker
359
Boltek’s StormTracker Lightning Detection System, powered by the software from Astrogenic systems,
360
define four types of lightning occurrences (CG- , CG+ cloud-to ground negative and positive, IC - ,
361
IC+ intracloud positive and negative, - in radii of 1, 3, 5 and 10 km around the location of its antenna).
364
StormTracker's antenna is a small black box (3"x2"x1-1/2") which may be mounted indoors or outdoors. The
365
antenna is typically mounted ten to twenty feet above the ground, away from large metal objects and
366
sources of electrical noise such as televisions and computer monitors.
370
*Detects if lightning is near.
371
*Receives early warning of approaching or developing storms.
372
*Configurable Severe Storm and Close Storm Alarms.
373
*Determines from which direction the approaching storm is coming.
374
*Follows developing and decaying storms from the first strike to the last.
375
*Saves all data for future analysis.
377
StormTracker works by detecting the radio signals produced by lightning. These are the same signals
378
you can hear on an AM radio during a thunderstorm. StormTracker's direction-finding antenna provides
379
direction information while storm distance is calculated from received signal strength. Special
380
processing in software reduces the effects of strike-to-strike energy variations providing more
381
accurate distance information.

The Cube assembly (Figure 1) consists of two 20-cm thick scintillators of 0.25-m^2 area each,
408
enfolded by 1-cm thick, 1-m^2 area scintillators. This design ensures that no particle may hit
409
the inside 20 cm without hitting the surrounding ‘‘veto’’ scintillators. The 20-cm thick plastic
410
scintillators are overviewed by the photomultiplier PM-49 with a large cathode operating in a
411
low-noise regime. Surrounding detectors (six units) are 1-cm thick molded plastic scintillators.
412
The efficiency of neutral component detection by 1-cm thick scintillators is ~2% and weakly
413
depends on the energy of gamma rays. The energy losses of passing electrons and muons in
414
20-cm-thick plastic scintillator are ~40 MeV. Taking into account the construction material
415
of the detector (2-mm iron tilt and 1-cm plastic scintillator), and the roof of the building
416
(1-mm iron tilt), the electron registration energy threshold for the upper 20-cm-thick scintillator
417
is estimated to be about 8 MeV and the bottom one ~40 MeV for the vertical flux. The obtained
418
efficiency of gamma ray registration equals ~20% and weakly depends on energy.
421

At the Nor-Amberd research station of ASEC we are starting tests of the operation of the SEVAN detector prototype (SEVAN #1) with slightly reduced sizes: area of upper and lower 5cm this scintillators are 0.65m, instead of 1m, and thickness of middle detector is 20cm, instead of 25cm. Also we establish the SEVAN detector prototype (SEVAN #2) in the Yerevan and in the Aragats (SEVAN #3). The dimensions of the upper and lower scintillaors are 1m, and thickness of middle detector is 20cm.

Incoming neutral particles undergo nuclear reactions in the thick 25cm plastic scintillator and produce protons and other charged particles. In the upper 5cm thick scintillator charged particles are registered very effectively; however for the nuclear interactions of neutral particles there is not enough substance. When a neutral particle traverses the top thin (5cm) scintillator, usually no signal is produced. The absence of the signal in the upper scintillators, coinciding with the signal in the middle scintillator, points to neutral particle detection. The coincidence of signals from the top and bottom scintillators indicates traversal of high energy muons. Lead absorbers improve efficiency of the neutral flux detection and filtered low energy charged particles. SEVAN world-wide network will consist of modules located in Croatia, Bulgaria, India (to be installe din 2008), Slovakia, Costa-Rica and Indonesia (to be installed in 2009).

Stand 1cm detector comprise of three-layer assembly of 1 cm thick 1 m^2 sensitive area molded plastic
623
scintillators one above the other and one 3 cm thick scintillator located aside (Figure 1).
626
Detector operates in particle counter regime. Outdoors location, 1-cm thickness and three-layer design
627
allow to measure flux of TGE electrons with 3 different energy thresholds starting from 1.5 MeV and to
628
recover integral spectrum of TGE electrons.
631
Light from scintillator by optical spectrum-shifter fibers is reradiated to the long wavelength region
632
and passed to the photomultiplier FEU-115M type photomultiplier (PM). The maximum of luminescence is
633
emitted at a 420-nm wavelength and the luminescence time is about 2.3 ns. The tuning of the Stand 1cm
634
detector consists in selections of PM high voltage and discrimination thresholds. The threshold should
635
be chosen to guarantee both high efficiency of signal detection and maximal suppression of PM noise.
636
Proper tuning of the detector provides ~99% efficiency of charged particle detection. The data acquisition
637
system counts and stores all coincidences of the detector channels.
640
Coincidence ‘‘100’’ means that only the upper detector registers a particle. This combination registered
641
low energy electrons with an efficiency of ~99% (we assume that the efficiency of electron registration
642
in the second scintillator also is 99%). We estimate the minimal energy of an electron stopping in the
643
upper detector and giving a signal to be ~1.4 MeV; it is the lowest energy threshold among all ASEC
644
detectors. Gamma ray detecting efficiency of this combination is about 2%. For the coincidence 010,
645
the gamma ray detection efficiency is increased to ~3% due to creation of electron-positron pairs in the
646
substance of the upper scintillator. Coincidence ‘‘111’’ means that all three layers register particles;
647
the minimal energy of charged particles giving a signal in all three layers is ~12 MeV. The energy
648
threshold of 3cm thick scintillators is ~5MeV.

[b]Ar[/b]agats [b]N[/b]eutron [b]M[/b]onitor ([b]ArNM[/b]) in operation at Aragats Station (40.47N, 44.18E, 3200m above sea level) since 2000 year. Neutron Monitore consist
673
“Stand 3cm” detector comprise of four-layer assembly of 3 cm thick 1 m2 sensitive area molded plastic
674
scintillators one above the other.
677
Tuning of Stand 3cm was made by means of the 8-channel signal analyzer developed at ASEC for online
678
data processing. Proper tuning of the detector provides 98–99% signal detection efficiency simultaneously
679
suppressing electronic noise down to 1–2%. The data acquisition (DAQ) electronics measures and stores
680
all coincidences of the signal appearance in the detector channels. Coincidence ‘’1000’’ corresponds
681
to signal registration only from upper scintillator, ‘‘1100’’ – from the first two upper scintillators,
682
and so on. GEANT4 simulations demonstrate that Stand 3cm detector can measure count rate of incident
683
electrons with energy thresholds 5, 15, 25, 35 MeV (combinations ‘‘1000’’, ‘‘1100’’, ‘‘1110’’ and ‘‘1111’’).
684
The 5 MeV electrons can give signal above the discrimination level only in the upper scintillator, to be
685
absorbed then in the scintillator body, or in the metallic tilts of scintillator housing; the 15 MeV
686
electrons can penetrate and be registered also in the second scintillator, and so on. In this way,
687
measuring the enhancements of count rates of above mentioned 4 combinations of detector layer operation
688
we can recover the integral energy spectra of TGE electrons, of course, after subtracting the gamma ray
692
The electronics signal threshold of Stand 3cm detector is ~3 MeV, thus, all 4 Stand 3cm layers can detect
693
gamma rays with energies greater than ~3 MeV, although with much smaller registration efficiencies comparing
694
with electron detection efficiencies. Gamma rays should have high enough energy to create high- energy
695
charged particles, which can reach bottom layer (the gamma ray energy should be above 40 MeV to generate
696
signal in all 4 layers with probability 1%).

Description of the measured parameters by the Davis Wireless Vantage Pro2 Plus:
755
[b]OUTSIDE AIR TEMPERATURE[/b]
757
The Davis Vantage Pro Plus uses the Integrated Sensor Suite's temperature sensor to measure the outside air temperature. A second temperature sensor in the console measures the inside air temperature.
762
Humidity itself simply refers to the amount of water vapor in the air. However, the amount of water vapor that the air can contain varies with air temperature and pressure. Relative humidity takes into account these factors and offers a humidity reading which reflects the amount of water vapor in the air as a percentage of the amount the air is capable of holding. Relative humidity, therefore, is not actually a measure of the amount of water vapor in the air, but a ratio of the air's water vapor content to its capacity. It is important to realize that relative humidity changes with temperature, pressure, and water vapor content. For a parcel of air with a capacity for 10 g of water vapor, which contains 4 g of water vapor, the relative humidity would be 40%. Adding 2 g more water vapor (for a total of 6 g) would change the humidity to 60%. If that same parcel of air is then warmed so that it has a capacity for 20 g of water vapor, the relative humidity drops to 30% even though the water vapor content does not change.
764
Relative humidity is an important factor in determining the amount of evaporation from plants and wet surfaces, since warm air with low humidity has a large capacity for extra water vapor.
769
Dew-point is the temperature to which air must be cooled for saturation (100% relative humidity) to occur, providing there is no change in water content. The dew-point is an important measurement used to predict the formation of dew, frost and fog. If dew-point and temperature are close together in the late afternoon when the air begins to turn colder, fog is likely during the night. Dew-point is also a good indicator of the air's actual water vapor content, unlike relative humidity, which also takes the air's temperature into account. High dew-point indicates high vapor content, low dew-point indicates low vapor content. In addition a high dew-point indicates a better chance of rain and severe thunderstorms. You can even use dew-point to predict the minimum overnight temperature. Providing no new fronts are expected overnight and the afternoon relative humidity is more than 50%, the afternoon's dew point gives you an idea of what minimum temperature to expect overnight, since the air is not likely to get colder than the dew-point anytime during the night.
774
Air that flows in relation to the earth's surface, generally horizontally. There are four areas of wind that could be measured: direction, speed, character (gusts and squalls), and shifts. Surface winds are measured by wind vanes and anemometers, while upper level winds are detected through pilot balloons, rawin, or aircraft reports.
776
The weather station measures direction, speed and gusts speed. Its anemometer is located two meters above the rooftop of the house.
781
The wind speed is measured with a so-called anemometer and is determined by counting rotation pulses over a sample period. The sample period is 2.25 seconds. The number of pulses per sample period is equal to the wind speed in miles per hour. In the database the wind speed is expressed in km/hr. The conversion factor for some frequently used units is as follows: 1 MPH = 1.6093 kph = 0.4470 m/sec = 0.8690 knots. The conversion to the well-known Beaufort scale is less obvious.
784
[b]Wind direction[/b]
786
The direction from which the wind is blowing. For example, an easterly wind is blowing from the east, not toward the east. It is reported with reference to true north, or 360 degrees on the compass, and expressed to the nearest 10 degrees, or to one of the 16 points of the compass (N, NE, WNW, etc.).
790
{| border="1px"
831
Wind run is a measure of the amount of wind which passes a given point during the measurement period. To calculate wind run, multiply the speed by the length of time in the measurement period. For example 10 km/hr for 12 hours would be 120 kilometers of wind run. Since the basic measuring period of the present weather station is one hour, the wind run is equal to the wind speed.
836
Wind Chill takes into account how the speed of the wind affects our perception of air temperature. Our bodies warm the surrounding air molecules by transferring heat from the skin. If there is no air movement, this insulating layer of warm air molecules stays next to the body and offers some protection from cooler air molecules. However, wind sweeps that comfy warm air surrounding the body away. The faster the wind blows, the faster the heat is carried away and the cooler you feel. Above 91° F, wind movement has no effect on the apparent temperature, so wind chill is the same as the outside temperature.
841
Heat Index uses the temperature and the relative humidity to determine how hot the air actually 'feels'. When humidity is low, the apparent temperature will be lower than the air temperature, since perspiration evaporates rapidly to cool the body. However, when humidity is high (i.e., the air is saturated with water vapor) the apparent temperature 'feels' higher than the actual air temperature, because perspiration evaporates more slowly. The heat index is only measured when the air temperature is above 14° c because it is insignificant at lower air temperatures. (Below 14° c, heat index = air temperature). The heat index is not calculated above 52° c.
844
[b]THW (Temperature - Humidity - Wind) Index[/b]
846
THW Index uses humidity and temperature to calculate an apparent temperature.
849
[b]THSW (Temperature - Humidity - Sun - Wind) Index[/b]
851
THSW Index uses humidity and temperature to calculate an apparent temperature. In addition, THSW incorporates the heating effects of direct solar radiation and the cooling effects of wind on our perception of temperature.
854
[b]BAROMETRIC PRESSURE[/b]
856
The weight of the air that makes up our atmosphere exerts a pressure on the surface of the earth. This pressure is known as atmospheric pressure. Generally, the more air above an area, the higher the atmospheric pressure, this, in turn, means that atmospheric pressure changes with altitude. For example, atmospheric pressure is greater at sea-level than on a mountain top. To compensate for this difference and facilitate comparison between locations with different altitudes, atmospheric pressure is generally adjusted to the equivalent sea-level pressure. This adjusted pressure is known as barometric pressure. In reality, the Davis Vantage Pro Plus measures atmospheric pressure, but then translates this to barometric pressure.
858
Barometric pressure also changes with local weather conditions, making barometric pressure an extremely important and useful weather forecasting tool. High pressure zones are usually associated with fair weather while low pressure zones are generally associated with poor weather. For forecasting purposes, however, the absolute barometric pressure value is generally less important than the change in barometric pressure. In general, rising pressure indicates improving weather conditions while falling pressure indicates deteriorating weather conditions
863
The average amount of rain measured in a time period. The weather station expresses this value in mm's per hour.
868
The amount of rain measured by the weather station in day time (between sunrise and sunset). The value has no meteorological meaning, but is merely determined to check the holiday weather conditions.
871
[b]SOLAR RADIATION[/b]
873
What we call 'current solar radiation' is technically known as Global Solar Radiation, a measure of the intensity of the sun's radiation reaching a horizontal surface. This irradiance includes both the direct component from the sun and the reflected component from the rest of the sky. The solar radiation reading gives a measure of the amount of solar radiation hitting the solar radiation sensor at any given time, expressed in Watts / sq.m (W/m²).
874
Bright sunshine is considered to be occurring when the solar radiation level exceeds 100 W/m², so we can easily work out how many hours of sunshine occur daily from this reading.
879
The amount of accumulated solar radiation energy over a period of time is measured in Langleys.
881
1 Langley = 11.622 Watt-hours per square meter = 3.687 BTUs per square foot = 41.84 kiloJoules per square meter
886
The UV Index measures the intensity of UV. It uses a scale of 0 to 16 to rate the current intensity of UV. The UV value logged by WeatherLink is the average UV measured during the archive interval. The UV sensor detects Ultraviolet Radiation at wavelengths of 290 to 390 nanometers. The US EPA categorizes the UV Index values as shown below:.
894
[b]COOLING DEGREE DAYS[/b]
896
Cooling degree days (CDD) are used to estimate the amount of air conditioning usage during the warm season. To calculate CDDs, you must first find the mean temperature for the day. This is usually done by taking the high and low temperature for the day, adding them together and dividing by two. If the mean temperature is at or below 18.3°C, then the CDD value is zero. If the mean temperature is above 18.3 °C, then the CDD amount equals the mean temperature minus 18.3 °C. For example, if the mean temperature was 25 °C then the CDD amount equals 6.7 °C.
898
We will not get a reading during the autumn and winter, unless we get a particularly hot day.
901
[b]HEATING DEGREE DAYS[/b]
903
Heating degree days (HDD) are used to estimate the amount of energy required for residential space heating during the cool season. To calculate the HDDs you must first find the mean temperature for the day. This is usually done by taking the high and low temperature for the day, adding them together and dividing by two. If the mean temperature is at or above 18.3 °C, then the HDD amount is zero. If the mean temperature is below 18.3 °C, then the HDD amount equals 18.3 minus the mean temperature. For example, if the mean temperature was 8.0 °C then the HDD amount equals 10.3 °C.
905
We will not get a reading during the spring and summer, unless we get a particularly cold day.

EvapoTranspiration (ET) is a measurement of the amount of water vapor returned to the air in a given area. It combines the amount of water vapor returned through evaporation (from wet vegetation surfaces and the stoma of leaves) with the amount of water vapor returned through transpiration (exhalings of moisture through plant skin) to arrive at a total. Effectively, ETo is the opposite of rainfall, and is expressed in the same units of measure (Inches or millimeters)
912
The Davis Vantage Pro Plus uses air temperature, relative humidity, average wind speed, and solar radiation data to estimate ET.
915
[b]Archive Interval (Arc. Int.)[/b]
917
Archive interval is user-selectable time-period from the following intervals (in minutes): 1, 5, 10, 15, 30, 60, or 120.
920
[b]Reception rate[/b]
922
The Reception rate shows the percentage of data packets that have been successfully received by the Vantage Pro console. It is a measure of the reception quality. Values above 90% are normal when the house is not occupied, otherwise the value can be as low as 20%. This is probably caused by interfering transmitters - e.g. notebook computers, or other MHz transmitters.
924
The ISS Reception numbers are intended to show the overall quality level of the radio reception between the Vantage Pro consoles and the ISS transmitter. The reception value is a percentage calculated from the number of wind speed samples received (reported in the “Wind Samp” column of the data browser) divided by the expected number of packets. The possible number of wind samples is based upon the transmitter ID and the archive interval period. Since wind speed data is in every data packet, it is possible to determine how many packets should have been received during the archive interval.

!Basic detecting unit of the SEVAN network at NorAmberd
684
Page Under Construction.
686
The basic detecting unit of the SEVAN network (see Figure 11) is assembled from standard slabs of 50x50x5cm plastic scintillators. Between 2 identical assemblies of 100x100x5m scintillators (four standard slabs) are located two 100x100x5cm lead absorbers and thick 50x50x25cm scintillator assembly (5 standard slabs). A scintillator light capture cone and [b]P[/b]hoto [b]M[/b]ultiplier [b]T[/b]ube ([b]PMT[/b]) are located on the top, bottom and the intermediate layers of detector. The detailed detector charts with all sizes are available from http://192.168.24.118/.

[i][b]Figure 1:[/b] The basic detecting unit of the SEVAN network.[/i]
695
At the Nor-Amberd research station of ASEC we are starting tests of the operation of the SEVAN detector prototype (SEVAN #1) with slightly reduced sizes: area of upper and lower 5cm this scintillators are 0.65m, instead of 1m, and thickness of middle detector is 20cm, instead of 25cm. Also we establish the SEVAN detector prototype (SEVAN #2) in the Yerevan and in the Aragats (SEVAN #3). The dimensions of the upper and lower scintillaors are 1m, and thickness of middle detector is 20cm.
697
Incoming neutral particles undergo nuclear reactions in the thick 25cm plastic scintillator and produce protons and other charged particles. In the upper 5cm thick scintillator charged particles are registered very effectively; however for the nuclear interactions of neutral particles there is not enough substance. When a neutral particle traverses the top thin (5cm) scintillator, usually no signal is produced. The absence of the signal in the upper scintillators, coinciding with the signal in the middle scintillator, points to neutral particle detection. The coincidence of signals from the top and bottom scintillators indicates traversal of high energy muons. Lead absorbers improve efficiency of the neutral flux detection and filtered low energy charged particles. SEVAN world-wide network will consist of modules located in Croatia, Bulgaria, India (to be installe din 2008), Slovakia, Costa-Rica and Indonesia (to be installed in 2009). We present data from SEVAN module operated at Nor Amberd research station, another module is under construction in Yerevan at altitude 1000m in CRD headquarters

!!Structure of the information content from SEVAN detector
701
The following information is providing by SEVAN detector:
703
*Count rates from the all 3 layers (see Table 16).
704
*Count rates of the all coincidences of upper, middle and lower detectors (see Table 16 and Table 17).
705
*Correlation matrix between all detected signals (Table 18)
707
In the directory “DEFAULT” the following information is stored:
709
*columns 1-3 - the count rates of all channels of the SEVAN. The count rates are posted in the Table 16;
710
*column 4 unused (this channel we can use as input of the atmospheric pressure sensor).
711
*columns 5-8 – the count rates of the coincidences of the all channels of the SEVAN. If we denote by the sign “1” signal from scintillator, and by sign “0” absence of signal, following combinations of the 3-layered detector output are stored: 110, 101, 011, 111 (see Table 16).

902
The basic detecting unit of the SEVAN network (see Figure 11) is assembled from standard slabs of 50x50x5cm plastic scintillators. Between 2 identical assemblies of 100x100x5m scintillators (four standard slabs) are located two 100x100x5cm lead absorbers and thick 50x50x25cm scintillator assembly (5 standard slabs). A scintillator light capture cone and [b]P[/b]hoto [b]M[/b]ultiplier [b]T[/b]ube ([b]PMT[/b]) are located on the top, bottom and the intermediate layers of detector. The detailed detector charts with all sizes are available from http://192.168.24.118/.

At the Nor-Amberd research station of ASEC we are starting tests of the operation of the SEVAN detector prototype (SEVAN #1) with slightly reduced sizes: area of upper and lower 5cm this scintillators are 0.65m, instead of 1m, and thickness of middle detector is 20cm, instead of 25cm. Also we establish the SEVAN detector prototype (SEVAN #2) in the Yerevan and in the Aragats (SEVAN #3). The dimensions of the upper and lower scintillaors are 1m, and thickness of middle detector is 20cm.
913
Incoming neutral particles undergo nuclear reactions in the thick 25cm plastic scintillator and produce protons and other charged particles. In the upper 5cm thick scintillator charged particles are registered very effectively; however for the nuclear interactions of neutral particles there is not enough substance. When a neutral particle traverses the top thin (5cm) scintillator, usually no signal is produced. The absence of the signal in the upper scintillators, coinciding with the signal in the middle scintillator, points to neutral particle detection. The coincidence of signals from the top and bottom scintillators indicates traversal of high energy muons. Lead absorbers improve efficiency of the neutral flux detection and filtered low energy charged particles. SEVAN world-wide network will consist of modules located in Croatia, Bulgaria, India (to be installe din 2008), Slovakia, Costa-Rica and Indonesia (to be installed in 2009). We present data from SEVAN module operated at Nor Amberd research station, another module is under construction in Yerevan at altitude 1000m in CRD headquarters

The basic detecting unit of the SEVAN network (see Figure 11) is assembled from standard slabs of 50x50x5cm plastic scintillators. Between 2 identical assemblies of 100x100x5m scintillators (four standard slabs) are located two 100x100x5cm lead absorbers and thick 50x50x25cm scintillator assembly (5 standard slabs). A scintillator light capture cone and [b]P[/b]hoto [b]M[/b]ultiplier [b]T[/b]ube ([b]PMT[/b]) are located on the top, bottom and the intermediate layers of detector. The detailed detector charts with all sizes are available from http://192.168.24.118/.

At the Nor-Amberd research station of ASEC we are starting tests of the operation of the SEVAN detector prototype (SEVAN #1) with slightly reduced sizes: area of upper and lower 5cm this scintillators are 0.65m, instead of 1m, and thickness of middle detector is 20cm, instead of 25cm. Also we establish the SEVAN detector prototype (SEVAN #2) in the Yerevan and in the Aragats (SEVAN #3). The dimensions of the upper and lower scintillaors are 1m, and thickness of middle detector is 20cm.
1053
Incoming neutral particles undergo nuclear reactions in the thick 25cm plastic scintillator and produce protons and other charged particles. In the upper 5cm thick scintillator charged particles are registered very effectively; however for the nuclear interactions of neutral particles there is not enough substance. When a neutral particle traverses the top thin (5cm) scintillator, usually no signal is produced. The absence of the signal in the upper scintillators, coinciding with the signal in the middle scintillator, points to neutral particle detection. The coincidence of signals from the top and bottom scintillators indicates traversal of high energy muons. Lead absorbers improve efficiency of the neutral flux detection and filtered low energy charged particles. SEVAN world-wide network will consist of modules located in Croatia, Bulgaria, India (to be installe din 2008), Slovakia, Costa-Rica and Indonesia (to be installed in 2009). We present data from SEVAN module operated at Nor Amberd research station, another module is under construction in Yerevan at altitude 1000m in CRD headquarters
