Simulating target positioning device

Abstract

The invention relates to a simulating target positioning device for diagnosis equipment of a laser nuclear fusion target chamber. The simulating target positioning device comprises a simulating target, a target feeding rod, a first linear positioning bearing and a linear motor, wherein the first linear positioning bearing is connected onto the target feeding rod in a sheathing manner; the linear motor drives the target feeding rod to do telescopic movement in the first linear positioning bearing along the axial direction of the linear motor; and the target feeding rod is movably connected with the simulating target. According to the simulating target positioning device, stable and smooth telescopic movement along the axial direction can be realized and high-accuracy position indication can be carried out on a theoretical target position of the diagnosis equipment.

Description

technical field [0001] The invention relates to a precise positioning device, in particular to a simulated target positioning device used for laser nuclear fusion target chamber diagnostic equipment. Background technique [0002] Laser nuclear fusion is a kind of artificial controllable nuclear fusion widely used at present. It has very important research significance in both civilian and military fields: it is to explore an inexhaustible clean nuclear energy for human beings; it is used to develop "clean" (No radioactive pollution) nuclear weapons, development of high-energy laser weapons; partial replacement of nuclear experiments. [0003] Therefore, laser nuclear fusion has been highly valued by the world's nuclear powers. Since the second half of the 1970s, Russia, the United States, Japan, France, China, Britain and other countries have successively started the development of high-power laser drivers. The United States is in a leading position in research in this fiel...

Problems solved by technology

[0009] However, the size of the test pellets currently used in China is relatively small—typically 200 microns. All diagnostic equipment must be aimed at such a tiny target when installed.

However, there is a common problem in the installation of diagnostic equipment at present, that is, it is very difficult to install the equipment in the best diagnostic position with high precision.
