Description
Summary:A detector utilizing a superconducting solenoid is being discussed for the Superconducting Super Collider (SSC). A useful field volume of 8-m diameter*16-m length at 1.5-2 T ( approximately 1 GJ at 2 T) is required. It has been decided that all of the particle physics calorimetry will be inside the bore of the solenoid and that there is no need for the coil and cryostat to be thin in radiation lengths. An iron yoke will reduce the excitation required and will provide muon identification and a redundant momentum measurement of the muons. A conceptual design was developed to meet these requirements. The magnet will use a copper-stabilized Nb-Ti conductor sized for a cryostable pool boiling heat flux of approximately 0.025 W/cm/sup 2/. The operating current, current density, coil subdivision, and dump resistor have been chosen to guarantee that the coil will be undamaged should a quench occur. The 5000 metric tons of calorimetry will be supported from the iron yoke through a trussed cylindrical shell structure separate from the cryostat. The coil and case, radiation shield, and stainless vacuum vessel would be fabricated and cryogenically tested as two 8-m sections.< >
