英文摘要	Helium helicon wave plasma (He-HWP) wall conditioning was performed with a specially designed antenna system on the Experimental Advanced Superconducting Tokamak (EAST) under strong magnetic field (0.5-1 T). The maximum effective RF power Peff was 30 kWat 27 MHz, and the He pressure was fixed at similar to 0.27 Pa. Charge-coupled device (CCD) images indicated that toroidal homogeneous but poloidal inhomogeneous He-HWPs were obtained. An obvious desorption of H2 and HD was found during He-HWP operation. Deuterium was desorbed mainly in the form of HD, with a removal rate of similar to 1021-1022D atoms/h. Additionally, the residual gas analyzer (RGA) results also showed a steep rise in H/D desorption during mode transition (inductively coupled plasma (ICP) -> HWP) with increased Peff from 5 to 15 kW, then a slight decline in the HWP mode with relatively higher Peff (>15 kW), which was further verified by the spectral data of hydrogen Balmer series (H alpha and D alpha).
