Abstract:

Its principal objective is to demonstrate the operation of electrostatic accelerator free-electron lasers in 1 the Far Infrared Radiation 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 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. It is for this reason that a considerable amount of FEL project time has been dedicated to the design of a high quality electron beam source and an electron transport and recovery system having a minimum amount of optical aberrations.
