| Abstract: | In order to clarify the contamination mechanism, the Monte Carlo method was used to simulate the complicated mass transfer process of gas contamination in the cooler. The performance degradation directly traceable to the gas contamination was analyzed. Subsequently, based on the theoretical study and practical experiences, some control procedures, including vacuum bake out, had been recommended. Furthermore, the systematization and standardization of cryocooler contamination control can be expected. |
