Abstract
CEBAF, The Continuous Electron Beam Accelerator Facility, is centered on a 4 GeV recirculating linac which has recently started routinely producing beam to the first of three experimental halls. Hall A, the second of three experimental halls, houses two high resolution spectrometers, HRS, and is due to become operational by the end of 1995. Each HRS consists of two nuclear physics detectors, with optics determined by a superconducting dipole and three superconducting quadrupoles cooled by the End Station Refrigerator, ESR. Minimization of the total heat load from Hall A to the refrigerator is essential since the capacity is fixed. The design, construction, and initial test of the cryogenic distribution system and how the overall heat load is controlled are discussed in this paper.
