ISNP/GNEIS Facility in Gatchina for Neutron Testing With Atmospheric-Like Spectrum
A description of the testing facility ISNP with spectrum resembling that of terrestrial neutron radiation developed at the PNPI (Gatchina) is given. A broad spectrum (1-1000 MeV) spallation neutron source of the facility with a neutron flux of 4 · 105 n/(cm2·s) is used for accelerated soft error testing. High-quality collimation of the neutron beam in conjunction with the TOF-technique enables to carry out precise and reliable monitoring of the neutron beam. The results of recent tests carried out at the ISNP by the Branch of JSC “URSC” - “ISDE” (Moscow) are presented.
