Abstract

The invention discloses a compact high-current diode capable of remotely adjusting beam parameters, which comprises a cathode seat arranged in a sealed space, an annular cathode arranged on the cathode seat, and an anode inner cylinder corresponding to the annular cathode, which is arranged in the anode The anode outer cylinder on the outer surface of the cylinder, the annular cathode and the anode inner cylinder are coaxially arranged, but the annular cathode and the anode inner cylinder do not overlap in the axial direction, the axial direction of the cathode seat is provided with a magnetic field, and the anode outer cylinder A magnetic field is provided in the axial direction, and the relative distance between the cathode and the anode inner cylinder can be adjusted, and the output impedance can be changed through the distance adjustment; Like the traditional diode, each adjustment needs to destroy the entire vacuum environment, which greatly improves the adjustment work efficiency, has outstanding substantive features and significant progress, and is suitable for large-scale promotion and application.

Description

technical field [0001] The invention relates to the field of diodes, in particular to a diode that can be remotely adjusted to generate high-impedance, high-voltage, high-current electron beams. Background technique [0002] The practical requirements of high-power microwave source systems put forward the requirements for power sources and microwave devices to further increase the power level while reducing volume and weight. Conventional high-power microwave amplification devices (such as RKA) have problems such as the operating frequency and the upper limit of output microwave power due to space charge effects. Improving the working impedance of the device and reducing the working current can reduce the influence of the space charge effect and improve the working efficiency of the device. At the same time, due to the lower power requirements of the front-stage driving source under the same working voltage condition, it is convenient for the miniaturization design of the wh...
