Abstract

A one-dimensional nonstationary model of relativistic carcinotrons, combines the particle-in-cell method in the description of an electron beam with a single-wave approximation in the description of the dynamics of an electromagnetic field. The influence of the intrinsic space charge of the beam is taken into account in the quasistatic approximation. A procedure is developed for computational experiment with a carcinotron in the axisymmetric approximation on the basis of the entirely electromagnetic code KARAT. The computations support the main known laws for a relativistic carcinotron. The effect the space charge has on inertial electron-beam bunching is examined. Mechanisms by which the space charge affects the carcinotron generation efficiency are demonstrated. The space charge may cause anomalously accelerated electrons in the beam and a reverse electron current to appear, increasing the impedance of the coaxial magnetically insulated diode that feeds the device. The carcinotron power and frequency are studied as functions of the strength of the guiding magnetic field. Cyclotron suppression of generation is confirmed. Calculation in combination with an electronic diode shows that generation at a higher frequency can be excited in the cyclotron "dip."
