AI Technical Summary

Technical Problem

Existing technologies lack vacuum performance testing devices for high-purity germanium detectors, which makes it impossible to detect vacuum degradation in a timely manner, affecting the accuracy and service life of the detectors.

Method used

A vacuum life measurement device for a high-purity germanium detector was designed, comprising a vacuum generation module and a detection component. The first and second detection modules detect the leakage and gas release volume and the getter's gas absorption capacity, respectively. Combined with a vacuum gauge and a getter test chamber, the vacuum life of the detector can be measured.

Benefits of technology

This technology enables effective detection of the vacuum performance of high-purity germanium detectors, ensuring long-term accuracy and maintenance support, and preventing increased leakage current and reduced energy resolution caused by vacuum degradation.
