In the ITER-like wall project, the JET tokamak will employ tungsten-coated carbon fibre reinforced composite (CFCs) tiles for the outer and inner divertor tile rows. In order to assure the performance under thermal loads at the JET divertor, high heat flux (HHF) tests are performed for the qualification during the series production of the W-coated tiles, some of which might be carried out in the JUDITH-2 facility of FZJ. The electron beam (EB) facility JUDITH-2 consists of an EB-gun, a process chamber with a vacuum system (vacuum chamber extension) and different cooling circuits. This paper presents a summary of preparation steps and the first demonstration of cyclic EB loading experiments with the JUDITH-2 facility. One W-coated CFC tile was loaded at an absorbed average power density of 2.86 MWm(-2). The cyclic EB loading time was 10.2 s. |
