| Abstract: | High vacuum multilayer insulation(HVMLI) cryogenic vessel was studied in this paper.The spectrums of the residual gases in HVMLI cryogenic vessel at various conditions were obtained by using residual gas analyzer(RGA).These conditions included opening the cold/hot cathode vacuum gauge and the different distance between hot cathode vacuum gauge and RGA.The results of the experimental investigation are as follows: The influence of the cold cathode vacuum gauge on the residual gases is negligible.A series of i... |
