Abstract :
The results of non-stationary simulation of helical electron beams (HEBs) parameters based on the PIC method and quasi-stationary model of electric field are presented. The beam types with different topology (laminar, boundary, regular intersecting) are considered. The evolution of the oscillatory velocity distribution is investigated. The space charge value of locked into adiabatic trap electrons and their life-time are obtained. The bombardment of the cathode by reflected electrons is studied
