Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiency that the prior art cannot avoid the pollution of the laser device when the laser device is used to provide the experimental environment for the toxic material, and provides a vacuum chamber application method for in-situ diagnosis of the toxic material based on the laser device. By using the vacuum chamber to load the toxic materials, on the basis of creating an experimental environment for in-situ diagnosis of toxic materials, the laser device is protected, so as to avoid the diffusion of toxic materials in the experiment and the contamination of the laser device.

Abstract

The invention discloses a vacuum cavity for in-situ diagnosis of toxic materials based on a laser device and an application method thereof. In communication, several observation windows are opened on the surface of the spherical cavity, and a vacuum valve is also arranged on the spherical cavity, and the vacuum valve is fixed and communicated with the spherical cavity. The invention uses the vacuum chamber to load the poisonous material, and protects the laser device while obtaining the desired experimental effect.

Description

technical field [0001] The invention relates to the experimental field of in-situ diagnosis of toxic materials, in particular to an application method of a vacuum cavity for in-situ diagnosis of toxic materials based on a laser device. Background technique [0002] Large-scale laser devices are loaded with high-power-density laser beams, which can provide ultra-high temperatures (10 6 K) Ultra-high pressure (10 12 Pa) and ultra-high strain rate (10 11 the s -1 ) and other extreme environments, providing an experimental platform for studying the physical and dynamic properties of materials under extreme conditions. [0003] Using such an extreme environment to study the characteristics of toxic materials can deepen researchers' understanding of toxic materials, and even discover the hidden characteristics of toxic materials. [0004] However, experiments with certain toxic materials can contaminate these large installations and even cause environmental pollution. Theref...
