The supporting device and driving circuit of cascaded electron beam diode suspension electrodes

Abstract

The invention relates to a supporting device for a cascade connection type electron beam diode suspension electrode and a driving circuit of the supporting device for the cascade connection type electron beam diode suspension electrode. The supporting device for the cascade connection type electron beam diode suspension electrode comprises three supporting units, wherein each supporting unit comprises a supporting pin, a shell body, a spring, an iron core and an electromagnetic coil, wherein each electromagnetic coil is installed outside the tube wall of each shell body, each spring is installed inside each shell body, each iron core is arranged at the front end of each spring, a through hole is formed in the center of each iron core, each iron core and each supporting pin are fixedly connected into a whole, and each supporting pin can move back and forth through electromagnetic force generated by each electromagnetic coil and through each spring, so that the cascade connection type electron beam diode suspension electrode is fixed and is released. Due to the fact that the supporting device for the cascade connection type electron beam diode suspension electrode and the driving circuit of the supporting device for the cascade connection type electron beam diode suspension electrode achieve suspension operation of the high-voltage electrode, the defect that a fixing support is not good enough in insulating performance under the action of high voltage, and has influence on distribution of electric fields is overcome.

Description

technical field [0001] The invention relates to the technical field of pulse power, in particular to a supporting device and a driving circuit of an electron beam cascaded diode floating electrode with multi-gap cascade operation. Background technique [0002] To carry out the research on the electromagnetic pulse effect of the system, it is necessary to establish a hard X-ray source with a high-energy fluence and an energy spectrum distribution between 20 and 120keV. The energy spectrum of the hard X-ray depends on the energy of the bremsstrahlung electron beam. Two or more stages of partial pressure reduce the energy of the electron beam, which can produce hard X-rays with large area, realistic energy spectrum and high energy fluence. Double Eagle in the United States has carried out two-stage and three-stage cascaded diodes and obtained good experimental data. [0003] In pulsed power technology, a vacuum diode acts as a load for a transmission line, and its function is ...

Problems solved by technology

[0006] Aiming at the problem that the suspension electrode support structure existing in the diode cascade has insufficient insulation performance under the action of high voltage and has an impact on the electric field distribution, a cascaded electron beam diode suspension electrode based on a movable support structure is proposed. The support device and its driving circuit, at the moment before the diode works, the support pin is removed by external force, the suspended electrode falls freely under the action of gravity, and the inertia of the object is used to realize the suspension of the middle electrode, realizing the instantaneous multi-gap diode cascade Work
