Research into tritium impact on the models of cryosorption panels under conditions simulating operation of a vacuum pump of fusion rectors

The paper presents the results of research in the tritium impact on sorption and thermomechanical properties of model cryopanels (MCP) of the ITER vacuum pumps. For the first time amount of residual tritium in a sorption layer of cryopanels was determined experimentally under conditions simulating the operation of the cryopump (sorption of a tritium-containing mixture at 5 K, desorption—at 80 K).
