Gary, Dale"Solar Microwave Imaging Spectroscopy & Electron Acceleration"AST-9987366The Owens Valley Solar Array radio telescope will provide a unique set of multifrequency microwave imaging observations of flares and active regions during the upcoming solar maximum period. The facility will be upgraded to accommodate additional baselines that will improve the spatial resolution of solar observations by up to a factor of three. During the next solar maximum period two primary scientific goals will be pursued: (1) development of three-dimensional imaging techniques to determine the emission source vs. height structure of transient structures in the solar atmosphere; and (2) a detailed investigation of the acceleration of high-energy particles due to magnetic field reconnection events. The latter investigation will provide critical radio frequency ground-based support for the NASA High-Energy Solar Spectroscopic Imager (HESSI) X-ray observations of the active Sun.Funding for this project was provided by the NSF programs for Stellar Astronomy & Astrophysics (AST/SAA) and Atmospheric Sciences Solar-Terrestrial Research (ATM/STR).***

“太阳微波成像光谱&电子加速”ast - 9987367欧文斯谷太阳能阵列射电望远镜将在即将到来的太阳活动极大期提供一套独特的多频微波成像观测耀斑和活动区域。该设施将进行升级，以容纳额外的基线，这将使太阳观测的空间分辨率提高三倍。在下一个太阳活动极大期，将实现两个主要的科学目标：(1)发展三维成像技术，以确定太阳大气中瞬变结构的发射源与高度结构；(2)详细研究了磁场重联事件引起的高能粒子加速。后一项研究将为NASA高能太阳光谱成像仪（HESSI）对活动太阳的x射线观测提供关键的射频地面支持。本项目由美国国家科学基金会恒星天文学和天体物理学（AST/SAA）和大气科学日地研究（ATM/STR）项目资助
