EMILIO SEGRE' OBSERVATORY, ISRAEL(ESOI)
The Mobile Cosmic Ray Neutron Monitor (6NM-64) was prepared in the frame of Israel-Italy Collaboration in Rome, and transported to Israel in June 1998. We did measurements of air pressure, total neutron monitor counting rate and intensities of neutron multiplicities m>=1, >=2, >=3, >=4, >=5, >=6, >=7 and >=8 in port Haifa (sea level), on the down station of Mt. Hermon ski lift (1400 m above sea level), and on the upper station of Mt. Hermon ski lift (2025 m). By these data we determined approximately cosmic ray barometric coefficients for total neutron monitor counting rate, as well as separately for integral multiplicities 1, 2, 3, 4, 5, 6, 7, and for >=8, and for average multiplicity by taking into account also information on primary cosmic ray variations on the basis of Rome neutron monitor data. From June 1998 the Israel-Italy Observatory (33 deg 18.3' N, 35 deg 47.2' E, 2025 m above sea level, Rc=10.8 GV) is working properly and furnishes computer-based one-minute data of cosmic ray neutron intensity (from two separate 3NM-64 sections) and neutron multiplicities >=1, >=2,>=3, >=4,>=5,>=6, >=7 and >=8, as well as information on air pressure, on internal temperature, internal humidity, lower voltage supply for electronics and higher voltage supply for Canadian neutron counters (to continuously control conditions inside the Observatory). Obtained data we used for determining barometric coefficients for properly determining of barometric corrections. By these coefficients we correct data of total neutron monitor counting rate and intensities of neutron multiplicities 1, 2, 3, 4, 5, 6, 7 and >=8 on change of air pressure. From January 1999 are established detectors of wind speed (for determining Bernoulli effect in cosmic rays) and of external air temperature (for approximately correcting data on temperature effect). From May 1999 the detector of atmospheric electric field EFS 1000 started to operate (for investigating of atmospheric electric field influence on cosmic ray intensity). The Observatory is named in honor of the great Italian scientist, Nobel Pricier Emilio Segre (1905-1989).
