Abstract

Abstract: The outgassing characters of probes installed inside the SUNIST vessel are evaluated by the device for measuring outgassing rate. The results show the influence isn’t important to the vacuum of SUNIST spherical tokamak. The discharging experiment supports this issue.

Key words: Outgassing rate, Magnetic probe, Eyelet conductance method, Spherical tokamak

摘要： 通过出气率测量装置评价了SUNIST装置的内部磁探针出气特性，实验结果表明其出气量和出气气体成分不足以影响SUNIST真空特性。其后的放电实验验证了这一结论。
