摘要

He-ICR cleanings were successfully carried out in 2006-2007 on the full superconducting tokamak (EAST), which is an ITER-relevant experimental tokamak. Factors influence on He-ICR efficiency, such as magnetic field, ICRF power and working pressure were investigated. In EAST, the breakdown pressure for He-ICR cleanings could reach 10 Pa. The removal efficiency for H during 20 kW 4.5 × 10^-3 Pa He-ICR cleaning was same as that in He-GDC cleaning (2 Pa, 4A). Highest H removal rate in EAST with full metallic material walls, 1.7 × 10²² H/h in 20 kW 3 × 10^-2 Pa He-ICR, was higher by a factor of four than that in HT-7 with carbon limiter configuration.
