| Title | Structural Analysis of Thermal Shields During a Quench of a Torus Magnet for the 12 GeV Upgrade | ||||
| Abstract | A magnet system consisting of six superconducting trapezoidal racetrack-type coils is being built for the Jefferson Lab 12GeV accelerator upgrade project. The magnet coils are wound with Superconducting Super Collider-36 NbTi strand Rutherford cable soldered into a copper channel. This paper details the analysis of eddy current effects during a quench event on the conduction cooled Torus magnet system. Each superconducting Toroidal coil is force cooled with supercritical helium gas which circulates in a tube which is in good thermal contact with the inside of the coil. Thin copper sheets are soldered to the helium cooling tube and wrap around the superconducting coil thus providing cooling to the rest of the coil pack. The coil is located within an aluminum coil case which is wrapped with multilayer insulation and surrounded by a liquid nitrogen-cooled thermal shield. Each coil assembly is surrounded by a vacuum jacket and all six Toroidal coils share a common vacuum. The coil case and | ||||
