Electrode structure for generating pulse point light source

Abstract

The invention discloses an electrode structure for generating a pulse point light source. The electrode structure comprises a heavy-current pulse source, a vacuum cavity, an output electrode, a conical cold cathode, a conical cold anode and a metal flange; a conical anode arranged opposite to the conical tip direction of the conical cold cathode serves as a loop electrode; the conical cold cathodeand the conical anode are equal in size, the two conical tips of the conical cold cathode and the conical anode are located in the same straight line, the conical tip parts of the conical cold cathode and the conical anode are provided with wire holes respectively, a metal wire is connected between the conical cold cathode and the conical anode through the wire holes, and therefore a wire load isformed. The loop electrode forms a loop through the vacuum cavity shell. According to the invention, an element substitution method is adopted; an unexpected effect is achieved: only one metal wire and two inherent electrodes are needed to replace the original multi-wire structure by replacing the original multi-wire part with the inherent electrodes, and as the inherent electrode design is adopted, the installation efficiency and the installation precision are effectively improved, and errors caused by fork point position deformation in the installation process of the multi-wire cross structure are avoided.

Description

technical field [0001] The invention relates to the field of pulsed rays, more specifically, it relates to an electrode structure for generating pulsed point light sources. Background technique [0002] In the pulsed high-voltage technology, in order to obtain a pulsed X-ray point light source with a diameter of 10 μm-30 μm, a high-current pulse source is often used to drive a crossed wire load to obtain it. The reason for using a crossed wire load to obtain an X-ray point light source is: in the past In conventional experiments, it was found that under the action of strong current pulse waves, crossing metal wires will firstly explode at the intersection point, and the vaporized metal wires will instantly condense into high-temperature and high-density plasma under the action of magnetic field pressure, and the radiation pulse For X-rays, the entire physical process occurs within a distance of 1mm up and down at the fork point. According to this phenomenon, the prior art us...
