一个测试CICC超导电缆性能的磁体试验装置已在中科院等离子体所建成.该装置包括一个5T－138mm口径的长均匀区背场超导磁体、一对可产生10T/s磁场变化率的脉冲超导磁体，以及人工超临界氦系统，它可以将高压室温氦气通过冷却变成可以冷却超导CICC导体的超临界氦.该装置能完全模拟环流器中迫流冷却式超导磁体导体所受到的诸如极向场磁体放电和等离子体破裂诸种强扰动的环境，测试CICC导体的性能.本文详细介绍了装置各部分参数和低温实验中测到的性能.
A magnet facility for testing CICC has been established in ASIPP. It consists of a 5T-138mm bore, superconducting background magnet, a pair of pulsed superconducting solenoids which can superimpose a dB/dt up to 10T/s during their discharge to the tested samples and a supercritical helium cooling system. This facility will be used to simulate the operating condition of CICC in tokamak S.C. Magnet system which are subjected to the disturbances due to the poloidal field magnet pulsed and plasma disruption. The magnet facility and it use to the CICC samples test will be described in detail in the paper.
