摘要：

磁重联过程是一种非常重要的等离子体物理过程，激光驱动磁重联实验是现在研究磁重联 过程的一个重要手段。质子成像技术能够精确地诊断等离子体的磁场结构，被广泛应用于激光驱 动磁重联实验中。现在主要发展出流量分析和粒子追踪两种方法通过实验中的质子成像结果重构 磁重联区域的磁场结构。研究人员从开始定性地分析实验结果，现在能够较精确地反演出磁场的 大小和结构分布，这对研究磁重联过程的物理性质提供了很大的帮助。本文回顾了质子成像技术 应用于激光驱动磁重联实验的一些重要结果，并对相关技术的发展进行展望，期望为研究人员继 续相关研究时提供参考。

Abstract:

Magnetic reconnection is an important basic physics progress, and laser driven magnetic reconnection experiment is a major research method. Proton radiography can accurately measure the magnetic filed of plasma, and it has been widely used in laser driven magnetic reconnection experiment. Currently, there are two methods to reconstruct the magnetic field from the experimental proton radiograph, ie. flux analysis and particle tracing. At the beginning, the researches only obtain the magnetic field qualitatively. With the development of technology, at present the accurate strength and distribution of magnetic field in the reconnection region can be reconstructed. It supplies many possibilities in the research of magnetic reconnection. This paper reviews several important results measured by proton radiography in laser driven magnetic reconnection experiments, and aims to provide a reference for researchers in related fields.

Key words: magnetic reconnection, magnetic field, plasma, proton radiography, laser
