	Three electrode gun, consisting of spherical cathode, control electrode and anode, has been designed. Anode potential was varying between 30 kV and 50 kV. For the each potential the control electrode potential has been chosen to achieve the smallest beam crossover in the middle of the first accelerator cell. Calculations was based on the model of the already existing gun – electron injector in the linear accelerator. Then all calculations for the different anode voltages has been repeated for the biger cathode, that means – different cathode electrode geometry. The result to use in the further accelerator calculations has been achieved.
