ALL TiC COATED LIMITER EXPERIMENT IN THE JIPP T-II TOKAMAK

All the aperture limiters in JIPP T-II were changed to be TiC coated graphite. The maximum density in this condition is 7.6×10^<13>cm^<-3> with the safety factor of 4.5,which is 2.7 times as high as the value obtained by the Murakami scaling. The z_<eff> values with this density and with a medium density of 2.4×10^<13>cm^<-3> are both close to unity after discharge cleaning for only 3 days. The behavior of limiter material release was found to be steady within a factor of two during the discharge, suggesting that the release mechanism is ion sputtering. Residual gas analysis also suggested that this sputtering is not chemical, which may be partly because the limiter surface temperature during the discharge is below 150℃.
