The Jefferson Lab Superconducting Accelerator
The Continuous Electron Beam Accelerator Facility (CEB AF) at the Jefferson Lab is a 5-pass recirculating superconducting linac capable of delivering beam simultaneously to three experimental halls. The accelerator contains 338 niobium cavities operating at 1497 MHz in superfluid helium and was designed to accelerate 200 liA of electrons to 4 GeV. Each cavity is individually powered by a 5 kW klystron and controlled in phase and amplitude. First beam delivery to halls C, A, and B occurred in November 1995, April 1996, and December 1996 respectively. During 1996, 6 nuclear physics experiments were successfully completed in hall C. An upgrade program to raise the maximum energy of the accelerator is under way, and single-pass energy of 1 GeV has already been achieved. Jefferson Lab is also applying its superconducting rf and accelerator technology to other applications such as a Free Electron Laser for Navy and industrial applications.
