11.3.2 Neutron Flux Meter
The flux meter is based on six CHM-15 proportional gas counters.
11.3.3 SEVAN
This cosmic rays detector is a part of developing SEVAN network (till now includ-
ing Armenia, Bulgaria, Croatia). The SEVAN detector and the network have been
developed in the CRD - YPI as an element of the Instrument Development Program
for the International Heliophysical Year.
One of the major advantages of this multi-particle detector is probing of the dif-
ferent populations of the primary cosmic rays, which initiated particle cascades in
terrestrial atmosphere. Fluxes of neutrons and gammas, charged components of low
energy and high energy muons are measured by a basic detector of SEVAN net-
work. This diverse information gives the opportunity to estimate the energy spectra
of the highest energy solar cosmic rays and distinguish very rare events of direct
solar neutron detection.
11.3.4 Cerenkov Light Telescope
The Cerenkov light telescope registers Cerenkov fluxes in air showers with energies

11.4 Telecommunication and Information System INRNE-BEO
The main task of the telecommunication system is to collect, transmit and archive
the measured data in SAP database (MaxDB), which is enlarged by:
•
stored data retrieval in accordance with the needs and permissions of the users
•
packing/unpacking
•
compressing/decompressing
•
raw data processing for visualization and presentation in human readable
format
The information system is a complex software system providing data flux con-
trol, data storage and data quality control. In state of implementation is Data
Acquisition Quality Assurance System (DAQAS). The system was developed
in UFS Zugspitze GAW station for improved data flow control and calibration
processes.
