The researches were carried out in UHV chamber and the pressure of residual gases did not exceed 5·10-9 torr. The structure of the cathodes surface was investigated by the Auger electron spectroscopy (AES). The measurement of emission properties of cathodes was made in a flat diode system in a pulse mode. The anode was the molybdenum plate (2×2×0.2 mm.), which was heating to the high temperature by the electron impact. Spacing interval the cathode-anode was equal to 1 mm and has been carefully controlled. Pulse duration of the anodic voltage is 4 μs. The amplitude of anodic voltage can change up to 5 kV. A work function of the samples was calculated by the method of a full current.
