TRAJECTORY ANALYSIS OF THE ELECTRONIC-OPTICAL SYSTEM OF TECHNOLOGICAL GYROTRON

The results of numerical modeling of the helical electronic beam formation system for technological gyrotron with operating frequency of 28 GHz are presented. The new code «ANGEL-2DS» designed to calculate the parameters of helical electronic beams in gyro-devices is described. Mathematical methods used in the code are briefly stated. We carried out the gyrotron trajectory analysis for the case of its usage for microwave processing of materials. The possibility of the formation of homogeneous helical electronic beams with a high degree of rotational energy is shown. The comparison of the calculated data obtained by various software with the experimental data is fulfilled. Accordance of calculation results to estimates of the electron beam parameters which are obtained by efficiency measurement is shown.
