It is shown that in a strong magnetic field, in which the density of the negative; space charge in a cylindrical gas magnetron reaches its maximum value, the equation for the discharge current is a particular case of the equation for the discharge current in a Penning discharge, reported previously by Reikhrudel et al. The value of (Hra)n , at which we find р=р_max for a given Va, is determined. The theoretical values are found to be in satisfactory agreement with the experimental values for various geometric and physical parameters.
