Studies of ion acceleration in a one meter laser controlled collective accelerator
(Institute of Electrical and Electronics Engineers, 1991)
The basic concept behind the Laser Controlled Beamfront
Experiment has been described in detail in previous
reports(1,2) In the experiment, control over the propagation
of a virtual cathode at the front of an intense ...
Collective ion acceleration via laser controlled ionization channel
(Institute of Electrical and Electronics Engineers, 1987)
Initial results from a successful laser-controlled
collective ion acceleration experiment at the
University of Maryland are presented. In the
experiment, positive ions are trapped in the potential
well at the head of ...

The generation of microwave radiation by the interaction
of a low-energy rotating electron beam (25 kV, 0.5 A, 5 ps) with an
azimuthally periodic magnetic wiggler field has been studied experimentally.
Narrow-band ...
Depressed collectors for a large orbit gyrotron
(1987-12)
An auxiliary magnetic cusp transforms
rotational motion in the spent beam of a Large-Orbit
Gyrotron into axial motion. Results
regarding the interfacing of this cusp with a
depressed collector region and the effects ...
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 ...
High-power microwave generation from large-orbit devices
(IEEE, 1988-04)
Experimental and theoretical studies at the University of
Maryland on the production of high-power microwave radiation in
cusp-injected, large-orbit devices are reviewed. Three classes of devices
belonging to this ...
Intense charged particle beam propagation into vacuum
(SPIE, 1998-01)
The propagation of intense charged particle beams into vacuum without the aid of
externally applied confining magnetic fields is under investigation both theoretically and
experimentally. In the configuration under study ...
High power plasma filled backward wave oscillators
(SPIE, 1988-01)
Relativistic backward wave oscillators (BWOs) have proven to be relatively efficient,
high-power microwave sources in the centimeter wavelength range. Recent Soviet results
have indicated that the use of a background ...
High power microwave generation from rotating e-layers in magnetron-type conducting boundary systems
(IEEE - Transactions on Nuclear Science, 1983-08)
Studies of the production of microwave and millimeter wave radiation at high harmonics of the relativistic electron cyclotron frequency by the interaction of a rotating E-layer with a multiresonator magnetron boundary ...
