Problems solved by technology

At present, it is found that the methods adopted by these devices have a common defect—there is no integrated implementation system. From parameter measurement, to parameter processing, to final judgment, each step is carried out separately, so the speed of obtaining results Slower, less efficient, and irregular

Abstract

This invention relates to a multiple laser systematic balance parameter measurement process device and a method, in which, the device includes: setting testing points of first class, second class and N class at the power balance position reviewed by said multiple laser system, setting a laser energy meter and a waveform collector at the collecting point of each class separately connecting with a computer network, which has an energy collecting software, a waveform collecting software, a data obtaining software and data process software. Said balancing method includes the following steps: automatic collection of energy data and waveform data, data process of them and the power balance diagnosis includes that of energy balance and waveform balance.

Description

Technical field [0001] The invention relates to a laser system for inertial confinement fusion and laser nuclear fusion, in particular to a multi-channel laser system power balance parameter measurement and processing device and a power balance method. Background technique [0002] The field of the present invention is Inertial Confinement Fusion (ICF for short). The so-called inertial confinement fusion is a realization of nuclear fusion. To put it simply, multiple high-energy laser pulses are used to irradiate a target nucleus composed of nuclear fusion materials from multiple different directions (generally multiple directions that are spatially symmetric), and compress it to produce a fusion reaction. In order to carry out the research of inertial confinement fusion, a large-scale laser device capable of generating multiple high-energy lasers must be built. At present, major scientific and technological countries in the world have built or are building such large-scale laser ...
