9303873 Canfield The PI requests funds to operate the new Imaging Vector Magnetograph at Mees Solar Observatory during the 1993 - 1995 period of declining solar activity, in support of both Max '91 campaigns and individual research projects. Several community-wide campaigns will take place during this period, associated with VLA observing periods, magnetograph campaigns, balloon flights, and rocket launches, and the PI will actively participate in these campaigns. As well, the PI will conduct an independent research program whose goals will include: 1. to determine from photospheric and chromospheric 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 H polarization during flares, and to understand its relationship to energetic protons in the ill-understood sub-MeV range; 4. to determine whether vertical currents observed in the photospheric emerge from below, or are generated after emergence by photospheric motions. ***

9303873坎菲尔德 PI要求在1993 - 1995年太阳活动减少期间提供资金，用于在Mees太阳观测站操作新的成像矢量磁力仪，以支持Max '91运动和个别研究项目。 在此期间，将开展几项社区范围的活动，与VLA观测期、磁力仪活动、气球飞行和火箭发射有关，PI将积极参与这些活动。 此外，PI将开展一项独立的研究计划，其目标包括： 1. 根据光球和色球矢量磁图确定产生耀斑的活动区域的日冕磁场是否不仅明显地是非势场，而且也是非无力场，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中体电子和非热电子加速和沉淀的形态关系; 3. 确定耀斑期间H极化的时间依赖性，并了解其与尚不清楚的亚MeV范围内高能质子的关系; 4. 以确定在光球中观察到的垂直电流是从下面出现的，还是在出现后由光球运动产生的。 ***
