Operating characteristics of the 1. 5 MJ pulsed superconducting coil

PDF Version Also Available for Download.

Description

It is demonstrated for the first time that a relatively large cryostable superconducting coil can be pulsed with relatively low ac losses at high ramping rates. The low ac losses with limited current sharing have been achieved by insulating the surface of the basic cable with thin organic film. The ac losses at 9 T/s are about 0.1% of the stored energy in the coil. After more than 4000 pulsing cycles, no changes in the pulsing characteristics and cryostability of the coil have been observed. The quench current of the coil is approximately 1 kA higher than the critical current ... continued below
