A Cryostat for Sample Irradiations in Liquid Argon
Irradiated ammonia, having relatively high polarizable contents and high resistivity to radiation damage is one of the preferable materials for polarized targets . The irradiation can be performed either in a cryostat of a polarized target (“low temperature” irradiation) at Tirr ≈1K, or in a medium of liquid argon (“high temperature” irradiation) at Tirr = 90K.
