【Abstract】 Helium refrigerator system is a significant component of cryogenic system in China spallation neutron source( CSNS),which is able to provide 2 200 W@ 18 K cold source for hydrogen circulation system. Firstly,the composition and device layout of CSNS helium refrigeration system are introduced. Then,commissioning principle and control interface of helium refrigerator system are introduced,and the installation and commissioning preparatory works are introduced detailedly. At last,the commissioning process are introduced in detail,and state parameters under three kinds of refrigeration power of 700 W/1 400 W/2200 W are obtained. The commissioning of the helium refrigerator system is finished smoothly and the results meet the acceptance indicator.更多还原
