Title: Nonlinear theory of the orotron with inclined electron beam

Abstract

In the conventional orotron (at least, in its classical configuration), a thickness of an electron beam propagating over the grating plate should be much smaller than a wavelength; also the clearance between the grating and the beam and possible misalignment should be smaller than this thickness. These requirements severely limit the choice of operating parameters and performance characteristics of this device. When a beam is slightly inclined to the grating surface, these limitations can be greatly mitigated: the operation can be more robust, beam thickness can be increased, so a higher microwave power can be generated. Such a configuration of the orotron with an inclined electron beam is studied in the present paper. The paper contains simplified equations describing nonlinear operation of such a device and results of numerical analysis of these equations with the electron velocity spread taken into account. The paper also contains a discussion of these results and their applicability to practical configurations, which can be designed for operation in the THz and sub-THz regions.

  • We describe a simple, nonlinear, self-consistent theory of the orotron (a Smith--Purcell free-electron laser) in which the relationship between output power, beam current, and beam accelerating voltage is obtained in closed form. This model explains certain features of the orotron observed experimentally that were previously poorly understood. Quantitative predictions of the theory are in good agreement with experiment.
  • The orotron is a device in which a sheet electron beam excites electromagnetic (EM) oscillations in an open resonator formed by a concave mirror and a periodic grating plate. The first spatial harmonic of a field near the grating has phase velocity close to electron velocity; therefore electrons streaming over the grating surface produce Cherenkov or Smith-Purcell radiation. The orotrons can be configured for producing coherent radiation at short millimeter and submillimeter wavelengths (up to the terahertz range). Typically the amplitude of the EM field in the orotron is rather small. Therefore, for extracting an appreciable part of electron kineticmore » energy, it is necessary to realize synchronous interaction between electrons and a slow wave at long enough distances. This peculiarity of the orotron operation makes it possible to develop an analytical nonlinear theory of the orotron. Such a theory showing how to optimize the choice of the interaction length and the ratio between ohmic and diffractive losses is developed in the present paper. The theoretical treatment is accompanied with consideration of practical effects limiting the orotron efficiency.« less
  • The nonlinear theory describing the interaction processes in traveling-wave-amplifier (TWT) and backward-wave-oscillator (BWO) configurations of pasotrons is developed. It is shown that space charge forces in electron bunches formed in the process of beam-wave interaction in the pasotron play a role completely different from that in linear-beam devices with a strong magnetic focusing of electron beams. While in the latter devices the space charge forces limit the device efficiency due to saturation of the axial bunching, in the pasotron they do not destroy electron bunches but cause the radial expansion of them, which may increase device efficiency. The role ofmore » these forces is compared with the ion focusing and the radial electric field of the wave, and it is shown that, under certain conditions, it may dominate. The efficiency of the pasotron-TWT with a phase-mixed beam well focused at the entrance may exceed 50%. In the pasotron-BWO, the efficiency is lower (up to 26% in the case studied), but it can grow as the equivalent of the Pierce gain parameter increases.« less
  • This paper investigates the generation mechanism responsible for the packets of electron cyclotron waves induced by an electron beam injected from the Space Shuttle and measured by Spacelab I instruments. The observed electron cyclotron emissions as well as their amplitude modulation are explained using a linear and a nonlinear treatments. Using a linear theory, it is shown that the emissions consist of the electronic Bernstein modes which are generated by an interaction between the neutralization return current and the ambient ionospheric plasma, and not directly by the primary beam. The observation of successive harmonic packets around the fundamental wave ismore » interpreted using a two-dimensional single-wave model of the nonlinear interaction between a finite size ring beam and an infinite homogeneous magnetized plasma. 43 refs.« less
  • A theory of operation of the orotron is described in which the electromagnetic field present in the open resonator of the device bunches the electron beam; this bunching leads to coherent oscillation. Theoretical results at 75 GHz are discussed.
