| Abstract: | The helium refrigerator is an indispensable component of a large space environment simulator,an important facility for radiometric calibration test of infrared cameras and cold welding test in an ultra-high vacuum condition for satellite movable parts.This paper discusses the components of the impurity removal system for a large helium refrigerator and its overall performance.For the helium refrigerator to operate steadily and effectively in a radiometric calibration test,the impurity removal system plays an important role. |
