A superconducting pulse coil set was constructed for transient stability 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) plasma initiation scenario, 2 T field drop from 7 T was tried with an approximate ramp rate of -25 T/s. This paper describes the design for the coil and presents the experimental results of its successful AC operation.
