A model of a space charge layer that may form between cathode and anode pla
smas in the presence of a transverse magnetic field is considered. Collisio
ns are assumed not to affect the motion of electrons in the gas. It is show
n that two solutions differing by cathode plasma parameters may take place.
Conditions when the effect of collisions may be ignored are found. (C) 200
