Enhancement of the 4-mm wavelength gyrotron efficiency by multistage energy recovery

Autor: Louksha Oleg, Trofimov Pavel, Malkin Alexander

Publikováno v: St. Petersburg Polytechnical University Journal: Physics and Mathematics, Vol 16, Iss 4 (2023)

This study presents the results of a complex physical modeling of a moderate power gyrotron operating at the 4-mm wavelength range. The characteristics of electrodes and magnetic coils in a four-stage recovery collector were optimized taking into acc

Development of multistage energy recovery system for gyrotrons

Autor: Trofimov Pavel, Louksha Oleg

Publikováno v: ITM Web of Conferences, Vol 30, p 02002 (2019)

A four-stage depressed collector based on spatial separation of electrons with different energies in the crossed electric and magnetic fields was developed for the experimental SPbPU gyrotron. Modeling of the system of electron energy recovery and an
