Abstract
The Continuous Electron Beam Accelerator Facility (CEBAF) is a new US Department of Energy (DoE) facility presently under construction in Virginia. CEBAF has elected to build particle spectrometers with superconducting magnets. Two high-resolution spectrometers will be built from separated function dipoles and quadrupoles. These magnets will be modular, permitting interchangeability between various spectrometers. A third spectrometer, having a large acceptance detector, will be built using a superconducting toroid. This toroid will have 8 superconducting coils with its axis aligned horizontally. The specification, design, cryogenics, and quench-protection aspects of these magnets are discussed. The superconducting quadrupole will have a 1-m bore, 1.8-m effective length and a 7.2-T/m gradient. The dipoles will be 1.7 T, homogeneous to 1 part in 10/sup 4/, in a field volume 1.2 m*0.3 m*3.12 m. The toroid will be 1-m inner diameter, 4-m outer diameter, and 4-m long with a peak field of 1.2 T.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
