Abstract
To develop a reliable divertor plate for large helical device(LHD), a test facility called ACT(Active Cooling Teststand) has been constructed in Toki site. The facility can generate 100 kW electron beams with beam energy of 30 keV as a heat source, which can irradiate with a heat flux of up to 100 MW/m{sup 2} to a test sample piece steadily. The beam irradiation area on the sample can be changed from 1 to 400 cm{sup 2} with a 64 step controller electrically. By using the ACT, the thermal fatigue tests of various kinds of carbon-copper brazed components are being performed under the heat loads of 2.5-14 MW/m{sup 2}. The test results show that several brazed components are applicable as the divertor plates for the first stage of LHD operation, namely with maximum heat load of 10 MW/m{sup 2} for 5 seconds discharge durations.
