CEBAF UV/IR FEL subsystem testing and validation program

A design has been established for IR and UV FELs within the Laser Processing Consortiumʹs (LPC) program for development and application of high-average-power FELs for materials processing. Hardware prototyping and testing for the IR portion of the system are underway. The driver portion has been designed based on the superconducting radio-frequency (SRF) technology now seeing large-scale application in the commissioning of CEBAF, the Continuous Electron Beam Accelerator Facility, where LPC activities are centered. As of July 1994, measurements of beam performance confirm SRFʹs benefits in beam quality and stability, which are applicable to high-average-power FELs.
