China Fusion Engineering Test Reactor (CFETR) is superconducting Tokamak device which is next-generation engineering reactor between ITER and DEMO. It is now being designed by China national integration design group. In the present design, its magnet system consists of 16 Toroidal Field (TF) coils, 6 Center Solenoid (CS) coils and 8 Poloidal Field (PF) coils. A helium refrigerator with an equivalent cooling capacity of 5kW at 4.5K for CFETR TF coil test facility is proposed. It can provide 3.7K & 4.5K supercritical helium for TF coil, 50K cold helium with a 10g/s flow rate for High Temperature superconducting (HTS) current leads and 50K cold helium with a cooling capacity of 1.5kW for thermal shield. This paper presents the conceptual design of cryogenic control system for CFETR TF coil test including of architecture, hardware design and software development.
