Research Abstract |
Pulse high heat loading experiment, high heat flux hydrogen/helium irradiation experiment, low energy and high flux deuterium/helium irradiation experiment have been carried out to investigate surface modification on tungsten due to the ITER ELM like loading. Modification of surface and cross section, microstructure change, hydrogen and helium retention and optical property change have been investigated. In addition, new developed tungsten materials have been fabricated and its heat and particle loading properties have been evaluated and optimization on tungsten materials has been carried out.
