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 ... -
Experimental studies of heavy ion collection acceleration at the University of Maryland
(IEEE, 1979-06)The collective acceleration of ions (H,C,N) from a well-localized ion source immediately downstream of a relativistic electron beam diode is experimentally investigated, The ions are produced either in a wellconfined gas ... -
Experimental studies of high power plasma filled backward wave oscillators
(IEEE, 1990-05-21)Summary form only given, as follows. It has previously been demonstrated that a plasma-loaded backward wave oscillator (BWO) powered by a relativistic electron beam can generate hundreds of megawatts of microwave radiation ... -
Experimental studies of high-power microwave reflection, transmission, and absorption from a plasma-covered plane conducting boundary
(The American Institute of Physics, 1991-05-01)Experimental studies of the reflection, transmission, and absorption of high-power microwave pulses from a plasma-covered plane conducting boundary are presented. Under optimum conditions, backscattered rf power is ... -
Experimental studies of overmoded relativistic backward-wave oscillators
(Institute of Electrical and Electronics Engineers, 1998-06)Internal field-emission breakdown in the electrodynamic structures of high-power microwave (HPM) devices can seriously limit the device’s output power and pulse duration. Increasing the diameter of the electrodynamic ... -
Experimental studies of the laser controlled collective ion accelerator
(Copyright 1989 American Institute of Physics. This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics., 1989-10-01)Detailed experimental studies of a collective acceleration experiment in which a time sequenced laser-generated ionization channel is used to control the propagation of an intense relativistic electron bearnfront are ... -
Experimental study of collective acceleration of ions from a localized gas cloud
(American Institute of Physics, 1981-02)The collective acceleration of ions (H, D, He, N, Ne; Ar, Kr, Xe) to peak energies of about 5 MeV/nucleon has been achieved using a 1.5-MeV, 35-kA, 30-ns electron beam pulse. Ion energies have been measured using ... -
Experimental study of millimeter wave radiation from a rotating electron beam in a rippled magnetic field
(American Institute of Physics, 1985-06)The generation of millimeter wave radiation from the interaction of a rotating electron beam (2 MeV, I kA, 5 nsec) with an azimuthally periodic wiggler magnetic field has been studied experimentally. Calculations of the ... -
Experimental study of propagation of intense relativistic electron beams in nonconducting vacuum drift tubes after passage through a localized plasma source
(American institute of physics - Journal of applied physics, 1987-04-01)Presents a study which examined the propagation of intense relativistic electron beams into evacuated nonconducting drift tubes after passage through a localized plasma source. Details of the time-integrated photographs ... -
Finishing one book and starting another
(Rochester Institute of Technology, 2006-08-31)Good morning and welcome to the academic year 2006-7. This year 2,803 faculty and staff will be working the magic that is RIT. There are 261 new faculty and staff. Will all the new faculty and staff rise so we can give ... -

However, permission to reprint/republish this material for advertising or promotional purposes or for creating new collective works for resale or redistribution to servers or lists, or to reuse any copyrighted component of this work in other works must be obtained from the IEEE., 1990-06)A three-wave free-electron laser (FEL) was operated with a powerful 8.4-GHz electromagnetic “pump” wave replacing the usual magnetostatic wiggler. The presence of a uniform axial magnetic field B,, produced cyclotron-harmonic ... -
Free electron laser with small period wiggler and sheet electron beam: A Study of the feasibility of operation at 300 GHz with 1 MW CW output power
(1989)The use of a small period wiggler (Cw < 1 cm) together with a sheet electron beam has been proposed as a low cost source of power for electron cyclotron resonance heating (ECRH) in magnetic fusion plasmas. Other potential ... -
A fundamental mode, high-power, large-orbit gyrotron using a rectangular interaction region

The Globalization problem for inner automorphisms and Skolem-Noether theorems
(World Science, 2003-07)We investigate the circumstances under which an inner automorphism of a ring with local units can be built from “local” information. Specifically, we consider three natural “inner” type properties for an automorphism of ... -
Grade inflation
(Rochester Institute of Technology, 2005-11)Recently, a lot of discussion across academia has centered on the phenomenon of “Grade Inflation”. It was first brought to the fore by the President of Harvard University a couple of years ago when he assumed office. ... -
Graded equivalence theory with applications
