Mechanical Properties of an Insulator for the Japanese LCT Coil
Superconducting fusion magnets operate in high electromagnetic forces at liquid helium temperature. Electrical insulators in a winding must sustain high compressive forces as well as high voltage. Far fewer studies have been made on mechanical properties than on electrical properties of insulation design. Therefore, we have investigated mechanical and electrical characteristics of several kinds of insulation materials at 4 K in order to select insulators for the Japanese LCT coil.1
