The Continuous Electron Beam Accelerator Facility (CEBAF) is a 4 GeV, multipass, CW accelerator. The machine is racetrack shaped with the linac split into two equal parts located in the straight sections. The recirculating magnets, which will guide the beam through four passes around the accelerating structure, are in the arc sections connecting the two linacs. At the end of the accelerator, the beam passes into the switchyard where it is guided into any of three experimental end stations. The linac consists of 418 Nb superconducting rf cavities operating at 1500 MHz to produce a high quality beam having a 100% duty cycle with an energy spread of 10/sup -4/ and emittance of 10/sup -9/ m. The operating temperature of the linac is 2K, based on a cost trade off between increasing rf heat loads with an increase in temperature, and an increasing cost of refrigeration to decrease temperature. A pair of High Resolution Spectrometers in Hall A and a high acceptance, high energy electron spectrometer in Hall C will utilize superconducting dipoles and quadrupoles. The Large Acceptance Spectrometer in Hall B is a six coil superconducting toroid.
