As the vacuum chamber of stainless steel is baked up to 320 掳C, the gas species of outgassing are analyzed by QMS (quadrupole mass spectrometer). After reached at a high vacuum of 2 脳 10 9 Pa, the outgassing from the hot cathode ionization gauge is mainly from the residual hydrogen ...

The outgassing behavior of A6063‐EX aluminum alloy and SUS 304 stainless steel has been studied by means of analyzing the outgassing rate curves and the residual gases in the vacuum system. The results indicate, when the chamber has been filled with moist gas, the major outgassing process is...
The outgassing characteristics of 304 stainless steel with different surface treatments have been measured. The surface treatments investigated were: (1) glass-bead shot blasting; (2) electropolishing with a surface roughness of 20–25 μ in.; (3) electropolishing with a surface roughness of 4–6...

A Type 304 stainless-steel vacuum system has been designed and constructed to study radiation-induced outgassing when this material is exposed to /sup 60/Co gamma radiation. An analytical model has been developed that predicts the outgassing from Type 304 stainless steel to be 5 x 10/sup -10...
Those who need a better vacuum, either in existing systems or for new construction, should be interested in this discussion, since there is at present no method of analysis to predict the bake time and temperature required to achieve a specific low outgassing rate from stainless steel. It has...
