Title: Simulation of the development and interaction of instabilities in a relativistic electron beam under variation of the beam wall thickness

Abstract

The development and interaction of Bursian and diocotron instabilities in an annular relativistic electron beam propagating in a cylindrical drift chamber are investigated analytically and numerically as functions of the beam wall thickness and the magnitude of the external uniform magnetic field. It is found that the interaction of instabilities results in the formation of a virtual cathode with a complicated rotating helical structure and several reflection regions (electron bunches) in the azimuthal direction. It is shown that the number of electron bunches in the azimuthal direction increases with decreasing beam wall thickness and depends in a complicated manner on the magnitude of the external magnetic field.

  • Parametric coupling between negative energy beam synchronous modes and positive energy plasma oscillation modes of a uniform beam-plasma system, due to the presence of sinusoidal density modulation in the monoenergetic, relativistic electron beam, have been theoretically investigated on the basis of linearized Vlasov--Poisson equations using a multiple-time-scale perturbation theoretical approach. It has been found that, for a given beam-to-plasma density ratio, there exists an upper limit to the initial beam energy for which the instabilities can be excited. Within the allowed range, maximum linear growth rate exhibits a minimum as the beam energy increases from its nonrelativistic value. To determinemore » the effectiveness of the parametric interaction process, feedback effects of the instabilities on the beam-plasma distribution functions have also been considered and estimates of energy transfers have been made. For typical parameters, the beam is found to lose about 15% of its initial kinetic energy during the ''hydrodynamic'' stage and the time required is about 4.72 nsec. (AIP)« less
  • For the system formed by a relativistic electron beam and its plasma return current, we investigate the effects of both transverse and parallel beam and plasma temperatures on the linear stability of collective electromagnetic modes. We focus on nonrelativistic temperatures and wave-vector orientations ranging from two-stream to filamentation instabilities. Water-bag distributions are used to model temperature effects and we discuss their relevance. Labeling {theta}{sub k} the angle between the beam and the wave vector, one or two critical angles {theta}{sub c,i} are determined exactly and separate the k space into two parts. Modes with {theta}{sub k}<{theta}{sub c}=min({theta}{sub c,i}) are quasilongitudinalmore » and poorly affected by any kind of temperature. Modes having {theta}{sub k}>{theta}{sub c} are very sensitive to transverse beam and plasma parallel temperatures. Also, parallel plasma temperature can trigger a transition between the beam-dependent filamentation instability ({theta}{sub k}={pi}/2) and the plasma-temperature-dependent Weibel instability so that two-stream, filamentation, and Weibel instabilities are eventually closely connected to each other. The maximum growth rate being reached for a mode with {theta}{sub k}<{theta}{sub c}, no temperature of any kind can significantly reduce it in the nonrelativistic temperature regime.« less
  • Construction of a variable thickness bolus modifies the electron beam penetration to accommodate differences in target thickness. This technique reduces the integral dose to underlying sensitive normal tissues, and permits increased flexibility in dose delivery to the designated volume. The technique has been found useful in electron beam irradiation of large chest wall lesions in 18 patients with recurrent, residual or suspected breast carcinoma post-mastectomy. The great flexibility allows individually tailored therapy. Patients tolerate the 5000-5600 rad delivered to the skin and the 4000 to 4500 delivered at depth in 6 weeks. Except for skin, which is at risk, theremore » are no adverse reactions. Residual disease received local boost irradiation. The pattern of response following this program is similar to that found for photon therapy.« less
  • Collisionless beam-plasma instabilities are expected to play a crucial role during the early phase of the relativistic electron transport in the Fast Ignition scheme. This Letter presents a theoretical study of these instabilities in a two-dimensional geometry, highlighting the role of unstable modes propagating obliquely to the beam direction. The main features identified through a linearized analysis in a very general kinetic framework are examined by means of a particle-in-cell simulation. Good agreement between the two approaches is observed in the linear phase. Beam trapping is found to account for the nonlinear wave saturation.
