Vacuum Impregnation with Epoxy of Large Superconducting Magnet Structures

  • Chapter

Part of the book series: Cryogenic Materials Series ((CRYMS))

Abstract

The Lawrence Berkeley Laboratory (LBL) has been building a series of thin solenoid magnets for use in high energy physics experiments.1, 2 , 3 The LBL thin-magnet concept integrates a superconducting coil, a shorted secondary and a tubular cooling system into a single-coil package. The magnet coil is vacuum impregnated with a low viscosity epoxy which, after casting and curing, forms an integrated crack-resistant package.
