Abstract
A double-layer anode structure high-current diode for radiation field focusing and a use method thereof, comprising a ring-shaped cathode plate, an outer-layer anode ring-shaped plate, an inner-layer anode ring-shaped plate and an anode target surface; the side surface of the inner-layer anode ring-shaped plate is provided with the anode target surface side by side, the ring-shaped cathode plate is sleeved outside the inner-layer anode ring-shaped plate and the anode target surface, and a first cavity is formed between the inner-layer anode ring-shaped plate and the anode target surface; the outer-layer anode ring-shaped plate is sleeved outside the ring-shaped cathode plate, and a second cavity is formed between the outer-layer anode ring-shaped plate and the ring-shaped cathode plate; the first cavity and the second cavity are communicated at the anode target surface. Through the design of the double-layer anode structure (the inner-layer anode ring-shaped plate and the outer-layer anode ring-shaped plate), the flow and focusing of the electron beam can be more effectively controlled. This structure helps to maintain the shape stability of the ring-shaped electron beam and reduces the diffusion and defocusing of the electron beam in the transmission process.
