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.
