Abstract

The invention relates to the technical field of impact compression, and particularly relates to a preparation system of a low-boiling-point light-gas gun loading test sample and a use method thereof.The system comprises a target device, a cooling mechanism and a sample preparation mechanism, wherein the target device comprises a sample chamber and a cooling chamber. The sample chamber is arrangedin the cooling chamber or the cooling chamber is arranged around the sample chamber; a sensor unit is arranged on the side wall of the sample chamber, and the sensor unit is used for detecting the temperature and the pressure in the sample chamber; the cooling mechanism comprises a cooling liquid tank, a cooling liquid inlet pipe and a cooling liquid outlet pipe; and the sample preparation mechanism comprises a sample gas storage tank, a sample injection pipe, a vacuum pump and a connecting pipe. According to the invention, the temperature of the sample in the sample chamber of the target device can be reduced to hundreds of DEG C below zero in an extremely short time according to the temperature requirement of an experiment, pure and stable samples such as liquid nitrogen and liquid hydrogen can be rapidly prepared in a short time, and the system has important significance for promoting the high-pressure research of low-boiling-point samples such as liquid nitrogen and liquid hydrogen.

Description

technical field [0001] The invention relates to the technical field of shock compression, in particular to a preparation system and a use method of a low boiling point light gas cannon loading test sample. Background technique [0002] High-pressure science and technology is a new subject that is in the stage of accelerated development. Most of the condensed matter in the universe is under high pressure. Under ultra-high pressure extreme conditions, the distance between atoms and molecules in condensed matter will be shortened, and the interaction will be significantly enhanced. The electrons in the inner layers of atoms can participate in bonding, and the original structure will be destroyed, resulting in structural phase transitions and changes in physical properties (changing Electromagnetic interaction state) and strong interaction between nucleons (nuclear reaction), synthesis of new materials, and even new physical phenomena. Therefore, research on the behavior of ma...
