Abstract

The High Momentum Spectrometer (HMS) became operational in June 1994 and is now in routine use as a nuclear physics spectrometer in Hall C at TJNAF. The commissioning including installation, cooldown, initial operation, testing and acceptance of the SC quadrupoles and SC dipole of the HMS will be discussed. Results of measurements performed on the magnets will be presented. The loss of a dipole current lead, failure analysis and the repairs will be discussed. A brief discussion of the Hall C SC magnet cryogenics will be included.
