| 摘 要： | 氦辉光放电清洗 (GDC(He) )是HL - 1M (环流器新一号 )托卡马克装置控制C、O杂质、壁H再循环和改善真空壁条件的有效方法。它与泰勒放电清洗 (TDC)、交流放电清洗 (AC)、电子回旋共振放电清洗 (ECR)相比 ,设备简单、不需要磁场且操作安全 ;与烘烤去气相比 ,它对环形真空室壁的去气率高 ,本底杂质浓度低。分别描述了去O、去C和去H的清洗模式 ,并提出了控制壁H再循环和壁清洁度的清洗指标

| Abstract: | The GDC(He) is an effective method for controlling wall H recycle and C, O impurities and improving the vacuum wall conditions in HL-1M tokamak.It is characterized of simplicity, no magnet and safety comparing with TDC,AC and ECR. Comparing with degassing bake-out,it has the higher degassing rate during GDC(He)and lower impurity concentration in vacuum chambers after GDC(He).The cleaning patterns of dominant de-oxygen,de-carbon and de-hydrogen are introduced and the cleaning parameters for wall H recycle and wall cleanness are suggested. |
