Measurements and simulation of controlled beamfront motion in the laser controlled collective accelerator
(Institute of Electrical and Electronics Engineers, 1989-03)In the Laser Controlled Collective Accelerator, an intense electron beam is injected at a current above the vacuum space charge limit into an initially evacuated drift tube. A plasma channel, produced by time-sequenced, ... -
Meeting the global challenge through diversity
(Rochester Institute of Technology, 2006-02-07)In what follows, we shall describe some of the key challenges facing the United States at this time. We shall cite some general macro economic statistics which describe the U.S. economy over time and in relationship to ... -
Microwave generation from rotating electron beams in magnetron-type waveguides
(American Institute of Physics, 1983-07)The production of high power microwave radiation at high harmonics of the electron cyclotron frequency by the interaction of a rotating electron beam with a magnetron-type conducting boundary has been studied theoretically ... -
Microwave generation in a high voltage triggered pseudospark discharge experiment
(American Institute of Physics, 1998-04-01)A set of five experiments to study the microwave emission accompanying the high voltage pseudospark discharge are reported. The generation of the microwaves in all cases but one is attributed to electron beam-plasma ... -

Narrow-band ... -
Middle of the fifth inning
(2000-09-05)Good morning and welcome. As an institution of higher learning, we are a special community – students, faculty, staff, administration, and trustees – all working together for a common goal. That goal is the education and ... -
Millimeter wave emission from a rotating electron ring in a rippled magnetic field
(American Institute of Physics, 1984-02-01)We report measurements of millimeter wave emission from a rotating relativistic electron ring (2 MY, 1 kA) in which electrons move in quasi-circular orbits under the combined action of a uniform axial magnetic field and ... -
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 ... -
Mind over matter: Transforming course management systems into effective learning environments
(EDUCAUSE, 2002-12)Integrating best practices for "deeper learning" with the robust tools provided by course management systems creates an incredibly effective, engaging, and student-centered learning environment. -
A Novel highly accurate synthetic technique for determination of the dispersive characteristics in periodic slow wave circuits
(IEEE, 1992-11)A novel, highly accurate (0.1-0.5%) synthetic technique for determining the complete dispersive characteristics of electromagnetic modes in a spatially periodic structure is presented. It was successfully applied for ... -
Novel method for determining the elctromagnetic dispersion relation of periodic slow wave structures
(©1990 American Institute of Physics, 1990-09-24)A novel method for calculating the dispersion relation of electromagnetic modes in an arbitrary periodic slow wave structure is reported. In this method it is sufficient to know the frequencies corresponding to three special ... -

Observation of a resonant enhancement of microwave radiation from a gas-filled backward wave oscillator
(American Institute of Physics, 1988-08-15)High-power microwave radiation at 8 GHz from a gas-fined backward wave oscillator driven by an intense relativistic electron beam has been measured. It has been observed that an order of magnitude resonant increase in ... -
On when a graded ring is graded equivalent to a crossed product
(American Mathmatical Society, 1996-04)Let R be a ring graded by a group G. We are concerned with describing those G-graded rings that are graded equivalent to G-crossed products. We give necessary and sufficient conditions for when a strongly graded ring ... -
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 ... -
