摘要: Heat flux and particle exhaust during ELMy H-mode were investigated using infrared TV camera, Langmuir probes Halpha detectors. The peak heat density reaches 400MW/m2 most of the power is deposited within a few milliseconds with PNB approximately 10MW. While scrape-off layer (SOL) current usually flows from outer divertor to inner ELM, occasional reversed at SOL accompanies broader profile.
