【Abstract】 HT-7U Tokamak, Which has been funded as a Chinese national science project, is a fully superconducting experimental device for nuclear fusion. The machine, consists of 16 toroidal field(TF) coils and 12 ploidal field(PF) coils,is cooled with 4.2K and 3.8K supercritical helium respectively. Cernox,a new type low temperature sensor, Cernox is adopted for measurement of coils system. The development of facility and the calibrating results are described in this paper.更多还原
