Abstract
The SARA facility at Grenoble provides the possibility to carry out neutron irradiation studies at both cryogenic and room temperatures, and permits at the same time to measure on-line the deterioration of the electronic performance of the tested circuits. The cryogenic vessel consists of a 101 liquid argon cryostat placed behind the neutron source. A TOF technique was used to measure the neutron energy spectrum produced by the collision of a 20 MeV deuteron beam on a thick Be target. Alanine and thermoluminescent dosimeters were used to determine the neutron and photon doses. The results show that the neutron and the gamma dose components are about 78% and 22%, respectively. The angular distribution of the dose was also measured.
