dc.description.abstract | The results of experiments with a short period (9.6
mm) wiggler sheet electron beam (1.0 mm x 2.0 cm) millimeter-wave
free electron laser (FEL) amplifier are presented. This FEL
amplifier utilized a strong wiggler field for sheet beam confinement
in the narrow beam dimension and an offset-pole side focusing
technique for the wide dimension beam confinement. The
beam analysis herein includes finite emittance and space-charge
effects. High-current beam propagation was achieved as a result
of extensive analytical studies and experimental optimization.
A design optimization resulted in a low sensitivity to structure
errors and beam velocity spread, as well as a low required beam
energy. A maximum gain of 24 dB was achieved with a 1-kW
injected signal power at 86 GHz, a 450-kV beam voltage, 17-A
beam current, 3.8-kG wiggler magnetic field, and a 74-period
wiggler length. The maximum gain with a one-watt injected
millimeter-wave power was observed to be over 30 dB. The
lower gain at higher injection power level indicates that the
device has approached saturation. The device was studied over
a broad range of experimental parameters. The experimental
results have a good agreement with expectations from a one-dimensional
simulation code. The successful operation of this
device has proven the feasibility of the original concept and
demonstrated the advantages of the sheet beam FEL amplifier.
The results of the studies will provide guidelines for the future
development of sheet beam FEL's and/or other kinds of sheet
beam devices. | en_US |
