摘要

Impurity control, edge plasma physics, acceptable recycling and proper plasma facing materials (PFMs) with long enough lifetime are the major concerns in plasma wall interaction (PWI) investigations in China. The wall conditioning using Ti getter, carbonization and boronization techniques have been conducted. Pump limiter and bias limiter were tested in HL-1 tokamak for impurity control. Low and middle-Z coatings have been developed and tested but the bonding between coating and matrix was not satisfactory enough. Graphite, doped graphite and C/C composite are now the main PFMs for current tokamaks in China. A significant modification of chemical sputtering (CS) resistance has been achieved using doped graphite. (C) 1997 Elsevier Science B.V. [References: 28]
