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 ...
Millimeter wave free electron laser amplifiers: Experiments and designs
(1991-08)
Free electron laser amplifiers are investigated as sources of high average-power (1 MW) millimeter to submillimeter wave radiation (200-600 GHz) for application to electron cyclotron resonance heating of magnetically ...
Experimental development of a millimeter wave free electron laser
(SPIE, 1990-12)
A 1 MW (cw), millimeter wave FEL (X, « 0.5 mm) is currently under development with an application for heating
fusion plasmas. Two salient features of the FEL are the use of a short-period wiggler £w < 10 mm) electromagnet
and ...
High-average-power CW FELs for application to plasma heating designs and experiments
(IEEE, 1990)
A short-period-wiggler (period - 1 cm), sheet-beam FEL has been proposed as a low-cost source of high-average-power (1 MW)
millimeter-wave radiation for plasma heating and space-based radar applications. Recent calculations ...
Progress in high power millimeter-wave FELs with short period wigglers and sheet electron beams
(Institute of Electrical and Electronics Engineers, 1989-05)
Short-period-wiggler free electron lasers with sheet electron beams
(Institute of Electrical and Electronics Engineers, 1988-06)
Propagation of wiggler focused relativistic sheet electron beams
(American Institute of Physics, 1988-02-09)
A recent design concept for millimeter-wave free-electron lasers [J. Appl, Phys, 60, 521
( 1986)] would require the stable propagation of a sheet electron beam through a narrow
waveguide channel. Experimental results ...
Low-voltage, megawatt free-electron lasers at a frequency near 300 GHz
(SPIE, 1988-01)
Design procedures and beam transport feasibility experiments Il.re discussed for a novel,
millimeter-wave free electron laser (FEL) concept employing short period magnetic
undulators and a sheet electron beam. The ...
A Short-period wiggler millimeter-wave free electron laser for plasma heating and space-borne radar
(1987-12)
We will report on the status of a new mm-wave
FEL research program based on short-period
electromagnet wigglers and a low voltage (500 kV)
sheet electron beam. Recent results of
measurements and theoretical modeling ...
