摘　　要：通过对 HL- 1M装置真空运行模式、真空运行参数、氦辉光放电清洗和硅化壁处理手段等的规范化 ,显著地改善了装置的真空壁出气、本底杂质浓度、托卡马克放电杂质出气比和再循环 ,成功地实现了高参数放电、长脉冲放电和装置暴露大气后快速恢复放电 ,并成功地为演证低混杂电流驱动、离子回旋共振加热、电子回旋共振加热、中性束注入、弹丸注入和分子束注入实验和升级等离子体运行等提供了良好的真空壁条件。描述了 HL- 1M装置真空系统、壁出气和再循环控制、质谱诊断和程序脉冲送气等方面的主要实验成果 ,并为 HL- 2By means of normalized vacuum operation models and vacuum operation parameters, GDC(He) and siliconzation wall conditioning considerably improve the vacuum outgasing-rate, the base impurity concentration and the impurity-degassing rate during tokamak discharges. H recycle, wall fuelling, high parameter discharges, long-pulse discharges and the rapid restitution discharges after exposure air are successfully obtained. The excellent vacuum wall conditions is provided for demonstrating the LHCD?ICRH?ECRH?MBI?PI and NBI experiments. The mainly experimental results, include of the vacuum system, the control of outgassing-rate and recycle, the mass spectrum diagnosis and gas puffing are described. It will be benefit to the vacuum system development and operation in the HL-2A Tokamak.
