Contamination Study: Temperature
Dependence of Outgassing S.W.K.
Yuan and D.T. Kuo BAE
Systems, Cryogenic Products Sylmar,
CA 91342 ABSTRACT With
the advance in technology, the life of the tactical cryocooler has extended
way beyond the conventional 4,000 hours milestone1.And
with the life extension, the contamination control of the manufacturing
process has to be revisited, or cooler life may fall short of expectation,
because outgassing is a function of time.This
means that cooler components need to be baked out at a higher temperature
or for a longer period of time.This
in turn requires the knowledge of outgassing rate as a function of temperature.
Contamination study of foreign gases and liquids in a cryocooler was discussed
elsewhere2.Outgassing
curves of water, alcohol, and acetone at 71°C
were presented in the above study.This
is a follow-up study emphasizing the temperature dependence of outgassing. Do You Know Someone Who Needs A Job in Engineering, Physics or Chemistry?
