Specific slow wave structures are needed in order
to produce coherent Cherenkov radiation in overmoded relativistic
generators. The electromagnetic characteristics of such
slow wave, resonant, finite length structures ...

We introduce a novel hybrid microwave amplifier
that utilizes the axial bunching mechanism of klystrons in
conjunction with the energy extraction mechanism of cyclotron
resonance masers. A simple analytic model is used ...
Characterization of electron beams generated in a high-voltage pulse-line-driven pseudospark discharge
(American Institute of Physics, 1994-05-01)
Emittance and energy measurements have been performed on a high-brightness electron beam
(>1010Nm2 rad2
) with diameter in the range 1-3 mm and energy in the range 150-170 keY. This
electron beam is generated by the ...
Periodic magnetic focusing of sheet electron beams
(American Institute of Physics, 1994-05)
Sheet electron beams focused by periodically cusped magnetic (PCM ) fields are stable against
low-frequency velocity-shear instabilities (such as the diocotron mode). This is in contrast to
the more familiar unstable ...
Experimental realization of millimeter-wave amplification by a sheet beam free electron laser
(American Institute of Physics, 1994-03-14)
We report an observation of millimeter-wave (94 GHz) amplification in a sheet beam, short period,
planar wiggler: free electron laser amplifier. The observed gain is about 5 dB for a 530 keV, 4 A
beam through a 54 cm ...
