Low temperature plane target and installation method thereof

Abstract

The present invention relates to a low temperature plane target. The low temperature plane target comprises a target core, a gasket, a detection window, an entering window and a gas filled tube. The target core is provided with a circular hole, and the circular hole and the target core are coaxially arranged; a connection hole is arranged at the side wall of the target core and communicates with the circular hole; the gas filled tube is connected with the connection hole, and an annular left side wall and an annular right side wall are disposed at the inner wall of the target core; holding cavities having an original thickness of 400[Mu]m are formed between the detection window, the entering window, the annular left side wall and the annular right side wall; the gasket is a circular ring cylinder, and the external diameter of the gasket is the same as the internal diameter of the circular hole; the detection window is a double-cylinder structure, the detection window includes a first cylinder and a second cylinder which are coaxially arranged, and the external diameter of the first cylinder is the same as the internal diameter of the circular hole; antireflection films coat the first cylinder and the second cylinder, and the entering window is a layered structure, so that the thickness requirement of liquids such as hydrogen, deuterium and the like in the laser physics experiment is satisfied.

Description

technical field [0001] The invention relates to a target, in particular to a low-temperature planar target which can be used to liquefy hydrogen, deuterium and other normal-temperature gases for related tests and experiments and an installation method thereof. Background technique [0002] In inertial confinement fusion (ICF) experiments, low-temperature targets have higher initial fuel density and lower shock wave preheating sensitivity, making it easier to achieve ignition targets. Hydrogen and deuterium are important materials in the experimental research of ICF, and the research on the equation of state of liquid hydrogen and liquid deuterium at low temperature is the key content of ICF. The target core is the carrier of the liquid deuterium material, and it is also the object that interacts with the laser in the construction of the low-temperature system in the laboratory. Its design, processing and assembly are directly related to the quality of the experimental result...

Problems solved by technology

[0003] In laser physics experiments, the laser needs to interact with liquid hydrogen and liquid deuterium through the incident layer, and use relevant diagnostic equipment to perform diagnostic tests at the subsequent interface. The thickness of liquids such as hydrogen and deuterium is required to be tens of microns to hundreds of microns. level, but in the current planar target structure, the thickness of hydrogen and deuterium liquid can only be controlled to more than a few hundred microns, and its design is complicated, the precision is high, and the processing and assembly are difficult. , deuterium and other liquid thickness requirements
