The G0 Superconducting Magnet System

The Superconducting Magnet System (SMS) is the heart of the G0 experiment. It consists of the superconducting coils which generate the magnetic field that focuses scattered particles onto the detectors. Also included in the scope of the SMS is any material that is part of the cold mass as well as cryogenic and vacuum support systems. In large part, the SMS will be fabricated by BWX Technology, which is responsible for the cryostat, coils, cryo reservoir and cooling system, and control system. Additional material and systems are provided either by JLab (power supply, integrated superconductor, vacuum system) or by UIUC (collimators, carriage, exit windows, lead collar) and integrated into the SMS at appropriate points in the assembly. A full test of the SMS will be carried out at UIUC before its shipment JLab and final installation in Hall C.

The status of the SMS (as of December 1998) is outlined in a section of the Report to PAC15. Earlier status information can be found in an appendix to the Cost and Schedule Review Report. Additional information concerning details of the G0 SMS is available below:
