分析了HT-7U大型全超导托卡马克装置低温杜瓦内的真空状况,对影响真空指标至关重要的磁体主机氦泄漏漏率作了计算,介绍了在试验杜瓦成功实现超导磁体正常运行的真空调试与检漏实践。
The vacuum condition of the HT-7U large all-superconducting tokamak device at low temperature Dewar was analyzed, and the helium leakage leakage rate of the magnet body, which is important to the vacuum index, was calculated. The experimental results show that when the superconducting magnet The normal operation of the vacuum test and leak detection practice.
