| Abstract: | Various methods to measure outgassing rate were summarized including the pressure rising rate collecting, weighing and gas flowrate. Based on the gas flowrate method, a new one was developed to measure outgassing rate, which can be used not only at room/high temperature but also at low temperature even down to about 100K. The measuring system is easy to operate and has a high precision. |
