Abstract :
Analysis and design details are provided on quench protection for the Cornell Electron Storage Ring (CESR) Phase III interaction region (IR) superconducting magnets. The proposed scheme extracts much of the stored energy thereby reducing thermal stress on the magnets and mitigating liquid helium loss. Protection is somewhat complicated by the fact that each cold mass consists of quadrupole, skew quadrupole and dipole windings, and that each cryostat contains two magnet units
