Abstract

Provided is an ICF pellet gas tube assembling precise calibration method, belonging to the ICF target automatic assembling field, and aiming to solve the problem of low assembling precision of a mode in which technical personnel observe and align at a pellet gas tube through a high magnification microscope. The method comprises: employing three sets of microscopic visual systems to monitor the center coordinate of a pellet from three different angles, and unifying three obtained pallet center coordinates to determine the coordinate system of the three sets of microscopic visual systems; utilizing the three sets of microscopic visual systems with a determined coordinate system to monitor the center coordinate of a pellet hole and the lower end coordinate of a gas tube; and adjusting the positions of the pallet hole and the gas tube to allow the center coordinate of the pellet hole and the lower end coordinate of the gas tube to coincide with the unified pellet center coordinate, thereby realizing exact alignment and calibration. The invention is used for cryogenic target precise assembling.

Description

technical field [0001] The invention belongs to the field of automatic assembly of targets in inertial confinement fusion (ICF). Background technique [0002] The idea of ​​inertial confinement fusion (ICF) is to use high-energy particle beams to compress deuterium-tritium target pellets to a high density of several hundred grams per cubic centimeter within a few nanoseconds, and the pressure is hundreds of millions of atmospheres, so that the target pellets are locally Forms hot spots that ignite and burn. In the late 1980s, American scientists successfully drove inertial confinement nuclear fusion using the radiation energy of underground nuclear explosions, confirming the feasibility of this technical route. [0003] With the emergence of laser technology, people began to study the use of high power density and excellent directivity of strong lasers to bombard deuterium-tritium targets, allowing them to produce controlled inertial confinement nuclear fusion to release fu...
