	E.A. Savin, S.V. Matsievskiy, N.P. Sobenin MEPhI, Moscow, Russia
	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.

	Funding: This work supported by the Russian Foundation for Basic Research (grant № 12-02-00866-а) For researches on plasma physics has been designed and constructed the electronic gun with the cold cathode on energy about 250 keV. The electron beam have the parameters: time width of pulses 100 ns, current amplitude 100 A. The adiabatic plasma lens is used to reduce the beam size to the demanded value. The results of tests are presented.
