The results ofinvestigation ofthe cathode emission properties influence on the pulse electron beam efficiencyextraction from generation chamber to the atmosphere through theexit window of the accelerator are presented. The experiments are based on the changes ofelectron diode impedance by variation the emission area of the cathode. A high-voltage pulse generator accelerator’s diagram is based on the discharge of capacitive energy storage to the diode through an autotransformer without intermediate forming lines. Thus, the output parameters of the accelerator are depend on the dynamic characteristics of diodesat constant parameters: the output voltage of the power supply, the output window of the accelerator design, etc. The needle cathode was investigated. Changing the diode impedance is achieved by changing the number of needles (22 and 44 needles), and by changing the value of the anode-cathode gap of diode.
