项目摘要

One of the most important problems in the study of solar flares is the understanding of the mechanisms of particle acceleration. An essential step in the solution of this problem is the determination of the characteristics of the accelerated particles. The characteristics observed or inferred from flare radiation, however, are not those of the accelerated particles but are these characteristics modified through interaction with the flare plasma. The aim of this research is the detailed investigation of these interactions with ambient plasma waves, particles and macroscopic magnetic and electric fields. This work will find application also in the study of electrons in the earth's ionosphere and many other situations. The results from this analysis are used for study of the impulsive phase gamma-rays hard x-ray, microwave and type III flare radiation. Many of the details of interaction of energetic particles have been analyzed under previous grants. This grant will complete some of these and begin investigation of effects of the geometry of flaring loops and their homogeneities on the observable quantities. It is intended to concentrate on some statistical analysis of the observations and begin work on acceleration mechanisms, initially in a manner that will be a natural extension of previous studies.
太阳耀斑研究中最重要的问题之一是对粒子加速机制的理解。解决这个问题的一个重要步骤是确定加速粒子的特性。然而,从耀斑辐射中观察到或推断出的特征并不是加速粒子的特征,而是这些特征通过与耀斑等离子体的相互作用而改变的。本研究的目的是详细研究这些与周围等离子体波、粒子和宏观磁场和电场的相互作用。这项工作也将在地球电离层和许多其他情况下的电子研究中得到应用。该分析结果用于脉冲相位伽玛射线、硬x射线、微波和III型耀斑辐射的研究。高能粒子相互作用的许多细节已经在以前的资助下进行了分析。这笔拨款将完成其中的一些工作,并开始研究耀斑环的几何形状及其均匀性对可观测量的影响。它的目的是集中对观测结果进行一些统计分析,并开始研究加速机制,最初的工作方式将是以往研究的自然延伸。
