Leak detection inside a vacuum vessel

  • 1. Jpn At Energy Res, Inst, Tokai

Description

A facility for leak detection inside a vacuum vessel is developed. It will take the place of conventional helium leak detection method. The facility consists of several devices; a unidirectional detector (a sensor), a vacuum tight manipulator, a simulated defect, a vacuum vessel with a turbomolecular pump system and others. Leak detection experiment on the facility was performed and the position of 3.0*10/sup -///6Torr/BULLET/1/sec helium leak was detected on condition that the sensor was at a distance of 18mm from the defect, and the pressure in the vacuum vessel was 5.0*10/sup -8/Torr
