%X The problem of focusing high current electron beam in a multi-electrode electron gun with magnetic field has been analysed theoretically. The cathode of the gun may be partially shielded magnetically. The paraxial-ray equation for describing the electron trajectory in the accelerating region is solved in closed form. The space charge effect has been included.
