摘要：

The tungsten divertor mock-ups were tested with high-heat fluxes in the e-beam facility and in the plasma device. The water-cooled mock-ups are tested with the combination of plasma and e-beam loads: (1) thermocyclic tests with the high-power electron beam load ranging from 5 to 40 MW/m(2) and then (2) tests in the PLM plasma device with stationary plasma loads of up to 5 MW/m(2). Such two tests are performed together for the first time. They simulate the variable loads onto the divertor plates, which can occur in the ITER during stationary discharges with transient ELM events. The duration of helium plasma discharges in the PLM amounted to 200 minutes. The temperature of the test targets heating amounted to 1000 degrees C and more.
