Abstract

For pt. I see IEEE Trans. Magn., vo1.30, p.2511, (1994). We report here on R/D work concerning two types of radiation-resistant magnet coils, which were insulated using completely inorganic materials. Regarding the first coil, the electric insulator employed was a alumina long fiber and a ceramic binder. A new combination of adhesive agent, inorganic filler and alumina long fiber was found, which enabled us to form a strong insulation layer which does not peel off from a copper conductor. The magnet coil for 2000 A excitation current was produced using this insulation method. The second coil is a mineral insulated cable (MIG) with a 3000 A excitation current. This 3000 A-class MIC has been manufactured as a short sample, and was tested concerning its electric insulation both before and after bending
