Abstract
This report presents the results of high heat flux experiment for a divertor mock-up by the use of an electron beam test system at KFA. The experiments were carried out at KFA on 1992 February under a collaboration between Japan and the European Community. The saddle-type divertor module, which was developed for ITER (International Thermonuclear Experimental Reactor), was tested at JUDITH (Juelicher Divertor Test Facility Hot Cells) in KFA. JUDITH is an electron beam test facility which can test radioactive materials. In this experiments, a thermal cycling experiment was performed at a heat flux of 15 MW/m{sup 2} to simulate the divertor plates in ITER. Moreover, a screening experiment and a disruption simulation experiment were carried out. As a result of the thermal cycling experiment, damage of the module, such like the detachment of the armor tile or the degradation of the thermal response, was not found during the experiment. No crack was observed at the surface of the module. In the screening experiment, the divertor module could withstand against a surface heat flux of 16 MW/m{sup 2} with a duration of 20 s. In disruption simulation experiment, the expected surface heat flux of 600 MW/m{sup 2} was applied to
