The results of a study on the formation of an electron beam by a magnetron gun with a secondary-emission cathode (cathode diameter 36 mm, an anode 78 mm) in the voltage range 25...90 kV are presented. The secondaryemission process in the gun is triggered by a voltage pulse with an amplitude of up to 16 kV applied to its anode. The generation of an electron beam is investigated as a function of the voltage of the incoming pulse. The dependence of the onset of electron beam generation on the beginning of the decay of the triggering pulse with its positive and negative polarity is studied. The dependence of the formation of the electron beam on the time of the secondary emission on the flat part of the voltage pulse was investigated.
