The Principal Investigator (PI) seeks to address an issue of solar physics that was recognized during the previous solar cycle as deserving particular attention: Coordinated observations of solar activity over a wide range of wavelengths from gamma- and X-rays to the infrared and radio wave regimes. The PI proposes to focus on solar microwave observations, which are relatively new in this panchromatic approach. In particular, the PI proposes to use and to expand the frequency- agile interferometer at Owens Valley, with its high spatial and spectral resolutions, and to study solar activity by microwave imaging and spectroscopy. Observations with this interferometer can accurately determine the strength and distribution of active- region magnetic fields and locate and parameterize thermal and non- thermal distributions of high energy electrons accelerated during flares.

首席研究员 (PI) 致力于解决上一个太阳周期期间被认为值得特别关注的太阳物理学问题：在从伽马射线和 X 射线到红外和无线电波范围的广泛波长范围内协调观测太阳活动。 PI 建议重点关注太阳微波观测，这在全色方法中相对较新。 特别是，PI建议使用和扩展欧文斯谷的频率捷变干涉仪，该干涉仪具有高空间和光谱分辨率，并通过微波成像和光谱研究太阳活动。 使用该干涉仪进行观测可以准确确定活动区域磁场的强度和分布，并对耀斑期间加速的高能电子的热分布和非热分布进行定位和参数化。
