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 gradient varying 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. 5mm spaced and 60{degree} on the cathode. Numerical analysis of the experimental system is performed. The operation modes and output power of signal are determined. The output power in X-band is greater than 27Mw, and the efficiency is above 1.0%.
