Compact high-current diode capable of remotely adjusting beam parameters

Abstract

The invention discloses a compact high-current diode capable of remotely adjusting beam parameters. The compact high-current diode comprises a cathode seat arranged in a sealed space, a ring-shaped cathode arranged on the cathode seat, an anode inner cylinder arranged corresponding to the ring-shaped cathode, and an anode outer cylinder arranged at an outer surface of the anode inner cylinder. Thering-shaped cathode and the anode inner cylinder are arranged coaxially and do not overlap in an axial direction. A magnetic field is arranged in the axial direction of the cathode seat. A magnetic field is arranged in the axial direction of the anode outer cylinder. The relative distance between the cathode and the anode inner cylinder can be adjusted, and output impedance can be changed by adjusting the distance. The compact high-current diode has the advantages of clever design, a simple structure and easy realization, the distance between the cathode and the anode can be remotely adjustedto adjust diode impedance instead of the need of destroying a whole vacuum environment in each time in traditional diode adjustment, the work efficiency of regulation is greatly improved, and the compact high-current diode has outstanding substantive features and significant progress and is suitable for large-scale 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...
