Design of the UCSB FEL electron beam system
The UCSB FEL experimental program was initiated January 15, 1980 at the Quantum Institute of the University of California at Santa Barbara. It's principal objective is to demonstrate the operation of electrostatic-accelerator free-electron lasers in (1) the FIR-submillimeter region at high average power and high overall efficiency using a single stage FEL; and (2) the visible-IR region with modest power and modest overall efficiency using a two-stage FEL. An important feature of the UCSB FEL is the recovery of the spent electron beam. Both (1) the average laser power and (2) the overall efficiency of the FEL increase with increased electron beam collection efficiency. Optimum laser performance can be achieved with this device provided only a small fraction of the total electric charge stored in the beam is lost while transporting it through the system. Realization of this low charge loss condition can be achieved only if a very high quality electron beam can be produced and maintained throughout the electron accelerator and transport system.
