[en] This report is one of the chapters of Japanese National Report of INTOR Workshop, Phase 2A. At this Phase 2A, the pumped limiter has been investigated as impurity control concept. The curved-surface double-edged pumped limiter was employed as results of various features. Surface materials are assessed from various aspects such as sputtering, behavior at plasma disruption, thermal characteristics, electro-magnetics, attachment method to substrate materials. Application of newly developed SiC with high thermal conductivity is also investigated. (author)
