Abstract

A high-precision controllable nozzle gas pool, consisting of: a supersonic gas valve, an adjustment platform, a prolate elliptical nozzle, a front baffle, a rear baffle, a front blade, a rear blade, a cache high-pressure gas cylinder, and a nozzle valve controller , the present invention can effectively provide a gas channel with steep edge density gradient and steady flow in the middle. It has the advantages of simple operation, convenience and high efficiency, high-precision adjustment, stable and controllable gas density distribution. The invention can be used in the field of laser plasma interaction, especially in the electron mechanism of laser plasma wake field acceleration, can provide a stable and adjustable gas medium channel, and can effectively solve the instability of gas channels generated by traditional capillary tubes and gas pools , Complicated operation, insufficient precision, high voltage and other shortcomings.

Description

technical field [0001] The invention relates to the generation of gas channel medium required in the field of ultrashort and ultrastrong laser plasma interaction and strong field physics, especially a high-precision controllable nozzle gas pool, which is used to generate steep changes in density at both ends and steady flow in the middle gas channel. The invention adopts a double-blade structure to cut jet air flow and prolate elliptical nozzle opening, combined with high-precision six-dimensional mobile platform, small holes at both ends for alignment and synchronous control, to realize gas channel generation with controllable density of multiple gases or single gas , has the advantages of simple operation, high precision, controllability and good stability. Background technique [0002] With the rapid development of laser wake field acceleration to produce high-energy electron beams and the laser plasma interaction field derived from the development of laser technology, t...
