dc.description.abstract | The design and feasibility of a I-MW continuous wave
(CW) free electron laser (FEL) oscillator are reviewed. The proposed
configuration will include a short-period (1" - I cm) planar wiggler.
a sheet electron beam, a 0.5-1.0 MV thermionic electron gun, a hybrid
waveguide/quasi-optical resonator, commercial de power supplies, and
a depressed collector. Cavity ohmic RF losses are estimated to be extremely
low ( 5 10-100 W/cm*) at I-MW output power, while thermal
heat transfer studies conservatively indicate that wall cooling up to 1500
W /cm' should be possible. Experiments have convincingly verified
theory and simulations which predict that negligible body currents will
be achievable with low-emittance low-space-charge sheet beams. Highvoltage
sheet beam gun design studies indicate that the required beam
quality can be achieved with CW compatible devices. The spent beam
energy distribution is consistent with highly efficient spent beam energy
recovery, and the proposed resonator cavity should provide mode
discrimination and beam/RF separation capability. Finally, recent advances
in superconducting wiggler designs suggest that even more compelling
improvements in FEL design are possible. Specifically, the substantially
increased dc wiggler fields can yield better beam confinement.
Furthermore, options for a strong-pump FEL amplifier with a tapered,
superconducting, short-period wiggler are now being considered. | en_US |
