介绍中国环流器2号A偏滤器托卡马克装置真空室总装检漏及结果。根据其真空室特点设计了不同结构的检漏子系统,用氦质谱检漏仪、四极场质谱计与氦质谱检漏仪相结合的方法(双质谱法)分别进行零部件和真空室总体检漏,对有关检漏技术问题进行了讨论。
Describe the leakage of the vacuum chamber assembly of No. 2 A divertor tokamak device in China and its result. According to the characteristics of the vacuum chamber, different structures of the leak detection subsystem are designed. The components and vacuum chamber overall inspection are carried out by means of helium mass spectrometer, quadrupole mass spectrometer and helium mass spectrometer (double mass spectrometry) Leakage, on the leak detection technology issues were discussed.
