Abstract

A 7 T experiment system, which was designed for a MRI superconducting switch test, has been developed at the Institute of High Energy Physics (IHEP) of China. The system mainly consists of a 7 T background superconducting coil, two pairs of 800 A vapor cooled current leads, a data acquisition system and more. The NbTi superconducting coil, with an operating current of 376 A, has a central field of 7 T and clear bore of 80 mm. The no-impregnation technique was adopted to fabricate this coil. The coil reached 96% of its short sample performance after three times quench. The system detailed experiments are presented in this paper.
