Embodiment Construction

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited by this.

[0026] see first figure 1 , figure 1 It is a schematic structural diagram of the high-precision controllable nozzle gas pool of the present invention. As can be seen from the figure, the structure of the high-precision controllable nozzle gas pool of the present invention is as follows: a supersonic gas valve 11 is fixed on a moving adjustment platform 14 with front and rear, left and right height and 360-degree rotation, and the upper end of the supersonic gas valve 11 is fixed. The external thread is linked with the internal thread of a prolate elliptical spout 8, and the periphery of the prolate ellipse spout 8 has two screw holes for two flat-head socket head cap screws 9 and 10 to be screwed into and fixed; Both sides of the oblong elliptical spout 8 are respectively p...

Abstract

The invention relates to a high-precision controllable nozzle air pool. The high-precision controllable nozzle air pool is formed by a supersonic speed air valve, an adjusting platform, a flat, long and oval nozzle, a front baffle, a back baffle, a front blade, a back blade, a buffer storage high-pressure air bottle and a nozzle air valve controller. The high-precision controllable nozzle air pool can effectively provide an air body channel, the density at the edges is changed in a gradient and steep mode, and flow in the middle is stable. The high-precision controllable nozzle air pool has the advantages of being simple in operation, convenient to use, efficient, high in adjustment precision, stable in air density distribution and controllable. The high-precision controllable nozzle air pool can be used in the field of laser plasma interaction, can be particularly applied to a laser plasma tail wave field acceleration electronic mechanism, can provide a stable and adjustable air medium channel, and can effectively solve the problems that a traditional capillary tube, a traditional air pool and the like are unstable, complex in operation, insufficient in precision, high in voltage and the like when the air channel is generated.

Description

technical field [0001] The invention relates to the generation of gas channel medium required in the field of ultra-short and ultra-intensive laser-plasma interaction and strong field physics, in particular to a high-precision controllable nozzle gas pool, which is used for generating abrupt changes in density at both ends and steady flow in the middle. gas channel. The invention adopts the double-blade structure to cut the jet air flow and the oblong elliptical nozzle port, and combines the high-precision six-dimensional moving platform, the alignment and synchronous control of the small holes at both ends, and realizes the gas channel generation of the mixture of multiple gases or the density of a single gas. , has the advantages of simple operation, high precision, controllability and good stability. Background technique [0002] With the rapid development of the field of laser-plasma interaction derived from the acceleration of the laser wake field to generate high-ener...
