Tandem high repetition frequency pulse generating device

Abstract

The invention belongs to the technical field of pulse power, and discloses a tandem high repetition frequency pulse generating device. The tandem high repetition frequency pulse generating device comprises one public transmission line, a plurality of middle tubes and a plurality of gas switches, wherein the public transmission line is a coaxial line, and a front port and a rear port are used as two output ends; the middle tubes are conductor round tubes with open two ends, and the plurality of middle tubes are orderly installed between an outer conductor and an inner conductor of the public transmission line at intervals, so as to form multistage double-tube pulse forming lines with the outer conductor and the inner conductor of the public transmission line; each double-tube pulse forming line includes one gas switch located at the middle part of the double-tube pulse forming line, and the working voltage of all gas switches is the same; and the multistage double-tube pulse forming lines work orderly from front to back at intervals. The high repetition frequency pulse generating device of the invention can generate two pulses whose repetition frequency can reach a ten thousand Hertz level, and can also generate one pulse string whose instantaneous repetition frequency can reach a megahertz level.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and relates to a serial high repetition frequency pulse generating device. Background technique [0002] Pulse power technology is widely used in particle accelerators, plasma technology, waste water and gas treatment and other fields. After decades of development, the output peak power of pulsed power sources has been greatly improved. One of the other main specifications of the pulsed power source is the repetition rate. With the expansion of applications, higher and higher requirements are put forward for the repetition frequency of the pulse power source. However, due to the limitation of the insulation recovery speed of the gas switch, the repetition frequency of the current pulse power source is generally tens of hertz to hundreds of hertz, and the highest does not exceed kilohertz. To increase the repetition frequency of the output pulse to more than several kilohertz, new research ...
