Abstract

The Japanese LCT coil has successfully achieved the design field of 8 T in the toroidal array of the six LCT coils. In March, 1986, tests of the LCT coils were started following the cooldown of the whole facility. In the single-coil test and design-point test, in which the maximum field was 6.4 T and 8.1 T, respectively, the coil was charged, discharged, and dumped under different conditions. A recovery test and a simulated nuclear heating test were performed to investigate the stability of the coil. Measurements of displacement under the several conditions of electromagnetic load were analyzed to explain the mechanical behavior of the coil. Results obtained in the tests are reported in this paper.
