A superconducting toroidal magnet for the CEBAF large acceptance spectrometer
The CEBAF (Continuous Electron Beam Accelerator Facility) physics program requires a large acceptance spectrometer covering nearly all of the 4{sup o} solid angle for studying complex electronuclear interactions. This device relies on a six-coil toroidal magnetic field to provide momentum analysis. The desire to maximize solid angle coverage led to a thin superconducting toroid design. The main device has an outside diameter of 4.6 m, an active length of 5 m, a peak field in the toroidal volume of 1.2 T, and a stored energy of 18 MJ. An intrinsically stable design was selected to minimize the overall space requirements of the toroid. The individual coils of the toroid are approximately kidney-shaped; the negative curvature provides a field-free region for targets coming from the requirement to have good particle focusing properties. The overall design is presented.
