Abstract:
Boronization with decaborane which is solid at room temperature has been successfully applied to the Compact Helical System (CHS) experiment. The effect of boronization on neutral-beam-injection (NBI)-heated plasma has been compared with the optimized case of titanium gettering. The concentration of oxygen has been reduced by a factor of 2 with boronization. Metal impurities can also be completely suppressed. Plasma performance has been improved in the high-density region with \bar n e 〉 5×10 19 m -3 . The effective lifetime covers at least 200 NBI discharges while the favorable condition with titanium gettering has an effective lifetime of only 20∼30 discharges.
