High heat flux experiments on divertor mock-ups with a thermal bond layer for fusion experimental reactors

High heat flux experiments were conducted on the divertor mock-ups with the thermal bond layer (TBL). The experiments were carried out at JAFRI Electron Beam Irradiation System (JEBIS). For the simulation of normal operation of ITER, the incident heat flux of MW/m2 at a maximum pulse duration of 50 s was loaded; and for the simulation of transient period of ITER, the heat flux of up to 15 MW/m2 at a maximum pulse duration of 10 s was loaded. The thermal performance of the mock-ups was stably sustained against both thermal loads. 5 refs., 8 figs., 1 tab
