In the year of 2016,the work of cryogenic group is mainly focused on cryomodules,operation of cryogenic system and preliminary design of CIADS cryogenic system.We completed the design,assembling and running of cryomodules in 2016,such as HCM6-2,HCM6-3 and SCM6-1.We tested mechanical character,sealing and vacuum performance of cryomodules by the means of cooling down and warming up several times before assembling in the injector II.So,they have been running stably.And ADS injector II with two cryomodules got proton beam with 10.06 MeV@1.16 mA for 28 min in CW mode,with 10.06 MeV@11.7 mA in pulse mode.Fig.1 shows the two cryomodules in injector II.The temperature,pressure,helium level of cryomodules can be read and written by cryogenic control system.All of these parameters matched design requirements.The helium pressure can be controlled at 1.05 bar±1.5 mbar,and helium level at 160 mm±10%.
