Descripción
Sumario:aA cold irradiation test facility operated at the IBR-2 reactor of JINR, Dubna, is used to investigate the behaviour under neutron and gamma irradiations of samples of materials and equipments to be used in the ATLAS forward (FCAL) and the hadronic end cap (HEC) liquid argon calorimeters. The samples under study are immersed in a liquid argon cryostat and exposed to fast neutron (E/sub n/ >or= 100 keV) fluences of about 10/sup 16/ n cm/sup -2/ equivalent to the neutron fluence accumulated in FCAL during ten years of LHC operation. An alpha -cell is used to check for possible outgassing due to irradiation of the samples immersed in liquid argon and to monitor the liquid argon purity. The results of various irradiation tests performed at this facility are reported. (6 refs).
