Development in the design of the superconducting toroidal magnet for the Continuous Electron Beam Accelerator Facility (CEBAF) large acceptance spectrometer

摘要

The magnet system comprises six flat, kidney-shaped coils arranged radially to produce a toroidal field with a peak value of 3.5 T. Features of the design discussed include a modular coil design allowing single coil works testing, an indirectly cooled aluminum-stabilized conductor, support of coils via in-plane warm tension links to each vacuum case, out-of-plane load sensing for alignment and fault sensing, passive internal quench protection, and an integrated instrumentation and control system.
