Fission-reactor-radiation-tests of MI-cables and magnetic coils for fusionburning plasma diagnostics

Magnetic probes for plasma diagnostics in the International Thermonuclear E xperimental Reactor (ITER) were developed and tested in a fission reactor, the Japan Materials Testing Reactor. Performance of coils made of mineral i nsulating cables could be analyzed by a proposed equivalent electrical circ uit but were disturbed by electrical drift, presumably caused by a phenomen on called radiation induced electromotive force. However, results were prom ising and development of an ITER-relevant magnetic probe is within view. (C ) Published by Elsevier Science B.V. All rights reserved.
