Abstract

Abstract: A system is designed to test the gettering performance of gas adsorption materials by using the principle of dynamic method, which can achieve high vacuum(5.0×10^-4Pa) to several atmospheres in the temperature range of 15-500K, measure the instantaneous adsorbing speed, adsorption capacity and saturation gas capacity of various materials for different gases accurately. The test results show that the system has the characteristics of high background vacuum, reasonable and compact structure, and accurate and reliable test data.

Key words: gas adsorption material, cryogenichigh-vacuum, system design
