Abstract
One of the most important research goals of EAST concerns long steady-state high-performance plasma pulse. It is a fusion engineering challenge for divertor to handle steady-state high heat flux form plasma. To accomplish this aim, full tungsten divertor has been designed for EAST to withstand high heat flux which is increasing rapidly. Full tungsten divertor is an ITER-like design which consists of monoblock units, end boxes and cassette body. The newest divertor of EAST will withstand more than 10 MW/m2 heat flux in target zone. The full tungsten divertor should be reliable during plasma discharge campaign to reduce the failure risk of plasma components under critical thermal power from plasma. Analysis and experiment results proved full tungsten divertor of EAST will be very reliable for future long steady-state high-performance plasma pulse. The design and application of full tungsten divertor of EAST can also bring experiences and answers for ITER or any next divertor fusion device on nuclear phase.
