Abstract

The invention relates to a cascade-stage-type electron beam diode. The diode comprises an electron beam diode body and one or more suspension electrode which is coaxially arranged between an anode of the diode and a cathode of the diode at intervals, and the suspension electrode is supported through a supporting device; the supporting device comprises a supporting needle, a shell, a spring, an iron core and an electromagnetic coil, the electromagnetic coil is installed outside the cylinder wall of the shell, the spring is installed in the shell, the iron core is arranged at the front end of the spring, a through hole is formed in the center of the iron core, and the iron core and the supporting needle are fixed into a whole; the supporting needle can move forwards and backwards under the action of electromagnetic force generated by the electromagnetic coil and the action of the spring to fix or loosen the suspension electrode. The diode achieves cascade-stage work of the multi-gap diode and can generate pulse X-ray sources low in energy spectrum.

Description

technical field [0001] The invention relates to the technical field of pulse power, and relates to an electron beam cascaded diode with multiple gaps cascaded. 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 to convert the high-power pulse energy formed by the transmission line ...
