Design study of a thin superconducting solenoid magnet for the SDC detector

摘要

A thin superconducting solenoid magnet has been designed for the SDC detector, which is one of major colliding particle detectors for the SSC high energy particle accelerator project. Based on recent R&D efforts to develop a high strength aluminum stabilized superconductor and a honeycomb/isogrid vacuum shell, the thin solenoid has been designed to provide a central magnetic field of 2 T in a tracking volume of 3.4 m phi *8.8 m, with a magnet wall transparency 1.2 Xo. The authors describe the conceptual design and the R&D work. To minimize material in the solenoid, technical guidelines incorporated into the solenoid design are outlined, and material savings are discussed. The cryostat and cryogenic design are considered. A R&D program is in progress to develop a prototype solenoid magnet with a full diameter and a quarter length to verify the SDC solenoid design.
