Abstract. Investigation results of onset conditions for multipactor discharge in output rectangular waveguides of the high power electron devices in the presence of focusing system magnetic dissipation fields are presented in this paper. The ratio of waveguide transverse sizes providing the possibility of the multipactor in the absence of the static magnetic field has been found taking into account electron emission velocity distributions and secondary emission coefficient curve for oxygen-free copper walls.

Key words: multipactor discharge, rectangular waveguide, static magnetic field, vacuum electron device.
