Suppression of parasitic secondary emission in a magnetron-injection gun of a 24-GHz technological gyrotron

This article analyzes the ways of reducing the parasitic emission current in the electron beam formation system of a technological gyrotron. The operation of the magnetron-injection gun in the quasi-critical mode and the profiling of the cathode can significantly reduce the space charge of electrons...

description	This article analyzes the ways of reducing the parasitic emission current in the electron beam formation system of a technological gyrotron. The operation of the magnetron-injection gun in the quasi-critical mode and the profiling of the cathode can significantly reduce the space charge of electrons captured in a magnetic trap between the gun and the entrance to the gyrotron working space. The calculated electron-gun configurations improve the beam quality, especially in the regimes with a high pitch factor.
