Paper Abstract

An experimental device of special high impedance, low beam current vircator is designed by means of the pulse-line electronic beam accelerator at UESTC according to the principle of virtual cathode microwave oscillator. A grandient varial region is linked between the drift tube and the diode in order to reducing the impedance of the diode. A strong pulse longitudinal magnetic field is applied, on the diode-drift region. A special plate-cathode mesh-anode structure is applied, there are annular grooves with 2.5 mm spaced and 60 degree on the cathode. Numerical analysis on experimental system are taken out. The operation modes and output power of signal are determined by the method of cooperation cold and hot measurment. The output power in X-band is greater than 27Mw, and the efficiency is above 1.0%.
