Design study of a phi 19.5*36 m superconducting solenoid (for supercollider Multi-TeV detector)

A large detector is being developed to measure teraelectronvolt massive objects decaying into muon pairs in a high luminosity (10/sup 33/-10/sup 34/ cm/sup -2/ s/sup -1/) pp collider. The mass resolution should be Delta M/M=1%. The momentum measurement of charged particles is achieved with the help of a very large superconducting solenoid which is surrounded by an octagonal iron yoke of 34770 tons. The magnetic field design, the design of the restraining cylinder, the thermosiphon cooling system, and the mechanical design are discussed.
