Abstract

The superconducting coil for the CEBAF High Momentum Spectrometer is under construction. The coil is a bath cooled system with an external coolant reservoir tank. Design and manufacturing procedures of the bobbin structure and coil are described. The overall coil/cryostat dimensions are about 7.3*3.9*1.9 m. The cooling system works on the thermal siphon principle. An outline of the conductor layout and its physical performance are shown. Bare conductors separated with special glass epoxy insulation spacers are used to get a sufficient surface for cryogenic stability. A special method for coil clamping has been developed to get sufficient mechanical prestress after cooldown and during operation up to nominal current.<>
