First operation of a 94 GHz, sheet beam, FEL amplifier
(Elsevier, 2002-10-14)
Millimeter wave (94 GHz) amplification has been observed in the sheet beam, planar wiggler, free electron laser. Using a 4 A sheet beam (20 mm × 1.0 mm) at an electron energy of 530 keV, injected wave power of 5 W was ...
Plasma influence on the dispersion properties of finite-length, corrugated waveguides
(The American Physical Society, 1996-03)
We present an experimental study of the electromagnetic properties of transverse magnetic modes in a
corrugated-wall cavity filled with a radially inhomogeneous plasma. The shifts of the .resonant frequencies of
a ...
Experimental and numerical results on a millimeter-wave free electron laser amplifier
(Elsveier - Nuclear instruments and methods in physics research, 1993-07)
Progress in studies of a millimeter-wave free electron laser amplifier based on a small period planar wiggler and a sheet electron beam is reported. Successful propagation of a 15 A sheet electron beam has been accomplished ...
From linearity towards chaos: Basic studies of relativistic backward-wave oscillators
(American Physical Society, 1992-09-14)
Recent experimental studies have revealed for the first time some basic features of pulsed. relativistic (300-600 keY) backward-wave oscillators such as starting current, axial mode locking, and multifrequency
operation. ...
