SUPERCONDUCTING PULSE COIL SET FOR STABILITY TEST OF SUPERCONDUCTING CABLES

A superconducting pulse coil set was constructed for transient stabili ty experiment of CICC (Cable-In-Conduit Conductor). The pulse coil set was composed of an inner and an outer coil connected in series. With 5 T background field, the pulse coil produced an additional 2 T on the CICC. In order to simulate the TPX (Tokamak Physics Experiment) plasm a initiation scenario, 2 T field drop from 7 T was tried with an appro ximate ramp rate of - 25 T/s. This paper describes the design for the pulse coil and presents the experimental results from its successful A C operation.
