Abstract. The cathode design was developed. This cathode provides a powerful pulse M-type device with a high repetition rate of high-frequency pulses and a long duration of high-frequency pulse. The developed design of the metal-ceramic cathode allows avoiding destruction of the emission bushing due to its deformation caused by pulsed thermal load. The problem of medium power removal from the cathode surface is solved. Dynamic tests of the device with this cathode are carried out. In the first hours of operation of the device, the area of stable operation at an anode current of the device was 80%. After a sixteen-hour run, the stable area for the anode current has decreased to 66% and stabilized. During the further run at 150 hours and tests for switching cycles, no significant changes in the operation of the device were recorded. This allows us to use this design for the serial production of high-power pulse M-type devices.

Key words: cathode, secondary emission, water-cooled cathode base, emitter, pulsed power.
