“…For the epoxy resin systems CTD101K, MSUT, CEA mix, Mix61, and MY750, the DMA results show that chain scission at 4.2 K occurs at a lower rate than at ambient temperature, confirming previous results showing a strong reduction of chain scission rates for irradiations in liquid nitrogen [29] and liquid helium [30]. For the Araldite F epoxy system, the aging rate appears to be similar for irradiations in air, inert gas, and liquid helium.…”

The superconducting magnets of future particle accelerators will be exposed to high irradiation doses at cryogenic temperatures. To investigate the effect of irradiation temperature and atmosphere on the aging behavior, we have characterized the changes in thermomechanical properties of six epoxy resins for potential use in superconducting magnets after irradiation up to 20 MGy in ambient air, inert gas, and liquid helium. Based on the results obtained by Dynamic Mechanical Analysis (DMA), we discuss the effect of irradiation temperature and the presence of oxygen. The irradiation temperature can have a strong influence on the rates at which cross-linking and chain scission occur.

“…The low temperature irradiation facility (TTB) at the 4 MW pool-type research reactor in Munich has already been described in a previous report [3] [4]. The reactor was used in the same conditions as in the previous tests with a nominal reactor power of 40 kW rather than the available 4 Mw.…”
