SPACER OF SUPERCONDUCTIVE MAGNET

摘要

PURPOSE:To maintain constant gaps between thermo excels when stress fatigue is exerted, by placing fiber base material impregnated with heat hardening resin between spacers and the surface of the thermo excels. CONSTITUTION:Thermo excels 9 having a uneven surface are provided to accelerate cooling by increasing contact area with a coolant at a passage of liquid He on the surface of coil conductor 2. Between the thermo excel surface 9 and the spacer 7, is placed a fiber base material 11 impregnated with heat hardening resin. The thickness of the base material 11 is preferably 1/4-1/3 of the thickness of the surface 9. The gap between the surfaces 9 is kept almost constant preventing slackness of the entire magnet and deterioration of cooling effect.
