Abstract

Electrical performance of insulation systems is critical to superconducting magnet devices such as those proposed for the International Thermonuclear Experimental Reactor (ITER). Reliability and radiation resistance of organic matrix composite insulation systems are a concern. This has prompted the search for alternate materials, particularly hybrid insulation systems which can be combined with organic composite primary insulation systems. Electrical strength of candidate insulation materials at 76 K have been investigated. Materials include mica based sheets, plasma-sprayed and porcelain enamel ceramic coatings, and polyimide films and coatings.
