Theory for high gain, high power free electron lasers
- Berkeley Research Associates, Inc., CA (USA)
In the past contracting period, the research on high gain, high power free electron lasers (FELs) has been fruitful. The findings have resulted in publications, presentations, and some important new research topics in progress. The work has been accomplished in close collaboration with the FEL physicists at LLNL including weekly visits to the LLNL Beam Research Building. The new research proposed is also coordinated closely with specific LLNL FEL project physicists, and the upcoming high-gain, high-power amplifier experiments during the next year on the Paladin FEL. The research includes analysis of the initial ELF experiments, identification of new FEL physics in Paladin at 5m length, electron beam distributions from future induction linacs, electron beam distributions in weak optical fields, a major FEL review paper, a simple understanding of FEL optical guiding, multimode analysis applied to single-pass FEL amplifiers, a LLNL review talk on FEL sidebands and electron distribution functions. 3 refs.
