Component tests on fast heating and cooling with cryopanels for use in the ITER primary vacuum system

Within the framework of the European Fusion Technology Programme, a primary vacuum pump for International Thermonuclear Experimental Reactor (ITER) is being developed. As the tritium inventory accumulated by the pumps must be limited, short pumping cycles are required. At two facilities, different fast heating and cooling techniques of cryosorption panels were investigated. The results for the most advantageous methods are presented. It is shown that fast regeneration of ITER cryopanels is technically feasible.
