Capillary discharging X-laser device using blumlein line and eliminating prepulse

Abstract

A capillary discharging X ray laser device adopting the Blumlein line and eliminating intrinsic pre-pulse relates to the capillary discharging X ray laser technical field. The invention solves defects that the intrinsic pre-pulse voltage can burn through vessel wall when a Blumlein transmission line is used between the existing Marx generator and the loads (capillary). The output end of a rapid high voltage electric pulse Marx generator (1) is connected with the input end of an intrinsic pulse insulation switch (4) through a main switch (2) and a Blumlein transmission line (3), the output end of the intrinsic pulse insulation switch (4) and one end of an insulation inductor (6) are connected with the electric pulse input end of the capillary and an X ray test assembly (7), another end of the insulation inductor (6) is connected with the output end of a pre-pulse generator (5). The invention prevents the intrinsic pre-pulse voltage of the Blumlein transmission line is passed, so the harm of the capillary wall ablation and the destroy of Z-pinch plasma are eliminated, so the invention can effectively output the laser.

Description

technical field [0001] The present invention relates to the field of capillary discharge X-ray laser technology. Background technique [0002] The existing capillary discharge X-ray laser system consists of four parts: 1. Energy storage part: it is a fast high-voltage electric pulse Marx generator, which provides energy for the next-level circuit. Second, the energy transmission part. 3. Capillary and pre-pulse circuit: the capillary is filled with a certain pressure of gas or metal vapor, first ionized by the pre-pulse into +1, +2 valence uniform plasma; under the action of the subsequent fast pulse and large current (main pulse), Pinch to form a high-density, high-temperature, high-ionization, and uniform plasma column. Under appropriate conditions, the electron collision process in it forms the inversion of the number of particles of the corresponding energy level, which can produce soft X-ray lasing . 4. Vacuum and detection system. [0003] The transmission efficien...

Problems solved by technology

[0005] The purpose of the present invention is to solve the inherent pre-pulse voltage brought by the use of the Blumlein transmission line between the Marx generator and the load (capillary) in the existing high-voltage, large-current, and fast-pulse discharge technology, which will cause abnormalities near the capillary wall. The uniform breakdown channel cannot rapidly separate the plasma from the tube wall when the main pulse arrives through effective Z pinch, resulting in the serious problem of tube wall ablation and seriously destroying the Z pinch process.
