Cryogenic target experiment device based on light-gas gun loading

The invention relates to the technical field of impact loading physical tests, specifically to a cryogenic target experiment device based on light-gas gun loading. The device comprises a shell and a detection mechanism, wherein a sample chamber and a cooling chamber are arranged in the shell; the cooling chamber is arranged around the sample chamber; a cooling hole and an air hole are formed in the side wall of the shell; an opening is formed in the right end of the sample chamber; the detection mechanism comprises a window, a detection pipe and a fixed station which are sequentially arrangedfrom left to right; the fixed station comprises a connecting part and a base part; and a sample hole, a cable hole and a temperature detection hole are sequentially formed in the fixed station. According to the invention, a corresponding coolant can be selected according to temperature requirements of impact experiments to reduce the temperature of the sample in the sample chamber of a target device to a temperature requi
