In order to provide a reliable experimental environment for ADS injectorⅡ, the cryogenic department designed a set of cryogenic system in the past year. This system includes the following aspects: compressor system, gas management control panel, cold box, external purifier, multi-channel cryogenic transfer-lines and valve box. The detailed flow chart is shown in Fig.1. This system is a cryogenic experimental facility, which can achieve different running modes, such as 4.2K and 2K liquid helium immersing cooling mode, forced flow cooling mode, distant dewar test mode and so on. Up to now, the liquid helium refrigerator, which is the core of the system, had been ordered from Linder Company, the maximum refrigerator power is 850 W/4.5 K, meanwhile, the other equipment is also being designed, investigated and purchased step by step.
