Paper Abstract

Experiments with helical electron beams (HEB) of powerful gyrotrons displayed the existense of intense nonstationary processes in HEB. The version of numerical simulation of HEBs is proposed which is based on the method of large particles. Some results of the analysis are given with account of the electrons reflected from the magnetic mirror and locked in the adiabatic trap. First of all, among the traced effects is intense bombardment of the cathode by the trapped electrons. Also, the formation of quasistationary states with their parameters (velocity spread, pitch-factor) essentially different from those given by the static theory was detected.
