The PI request funds to operate the new Imaging Vector Magnetograph at Mees Solar Observatory during the period of high solar activity, in support of both Max '91 campaigns and individual research projects. The goals of his individual research projects include: (1) to determine from photospheric vector magnetograms whether coronal magnetic fields in flare-productive active regions are demonstrably not only non-potential, but also non-force- free, and to understand the origin of such departures; (2) to understand the morphological relationship of photospheric magnetic fields and current systems to bulk energization and nonthermal electron acceleration and precipitation in flares; (3) to determine the temporal dependence of Ho polarization during flares, and to understand its relationship to energetic protons in the ill-understood sub-Mev range. ***

PI要求在太阳活动高峰期间在Mees太阳观测站运行新的成像矢量磁图仪，以支持Max '91运动和个人研究项目。他的个人研究项目的目标包括：(1)从光球矢量磁图中确定耀斑产生活跃区域的日冕磁场是否明显地不仅是非势磁场，而且是非力磁场，并了解这种偏离的起源；(2)了解光球磁场和电流系统与耀斑体能量和非热电子加速和沉淀的形态关系；(3)确定耀斑期间Ho极化的时间依赖性，并了解其与亚mev范围内高能质子的关系。* * *
