Abstract

The invention provides a method and apparatus for measuring a plasma state, a method and apparatus for controlling plasma discharge, and a computer readable storage medium. The method for measuring the plasma state comprises the following steps: acquiring a first quantity of detection data at a cross section position of plasma under ray irradiation; preprocessing the detection data to generate a second quantity of second data, the second quantity being greater than the first quantity; extracting a feature value of the second data based on a convolutional neural network model, the convolutionalneural network model being generated by machine learning of the plurality of training samples; and generating, based on the feature value, two-dimensional radiation distribution data indicative of the cross section position. The scheme for measuring the state of the plasma and controlling the discharge of the plasma can accurately deduce and / or control the state of the plasma.

Description

technical field [0001] The present disclosure relates to tomography for plasmas, and more particularly, to methods and apparatuses for measuring plasma states, methods, apparatuses, and computer-readable storage media for controlling plasma discharges. Background technique [0002] A plasma is a collection of unbound states composed of a large number of charged particles. Plasma can be used in many fields. For example, in the field of nuclear fusion experiments, the main technical difficulty at present is how to confine the high-temperature plasma in the core of the nuclear fusion reactor, so as to prevent the plasma from breaking free and touching the container of the experimental device, thereby causing damage to the experimental device. damage. Because the plasma in the nuclear fusion experimental device is under extreme environmental conditions (such as ultra-high temperature). It is difficult for general measuring devices to measure the distribution state of plasma. ...
