The electromagnetic fields of the higher order axial
resonant modes in a slow wave structure are analyzed and found
to have considerably different characteristics from those of the
conventional fundamental mode. Here, ...
Starting energy and current for a large diameter finite length backward wave oscillator operated at the fundamental mode

We study the starting conditions for a large diameter
(diameter/wavelength = 4.8) finite length backward wave oscillator
designed for 24-GHz operation at the fundamental T M o l
mode. This geometry is very promising for ...
Electromagnetic properties of open and closed overmoded slow-wave resonators for interaction with relativistic electron beams

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 ...
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 ...
Theoretical and experimental investigations of the cyclotron interaction effect on relativistic backward wave oscillator operation
(SPIE, 1993)
Microwave sources based on backward-wave oscillators (BWOs) driven by relativistic electron beams are capable of producing high power coherent radiation in the cm and mm wavelength region. When the axial magnetic field is ...
Linear analysis of a finite length plasma-filled backward wave oscillator
(American Institute of Physics, 1992-04)
Absolute instability in a plasma-filled backward wave oscillator with sinusoidally corrugated
slow wave structure driven by an intense relativistic electron beam has been analyzed
numerically. The maximum spatial growth ...
