Solar Microwave Spectroscopy at Owens Valley During Max '91

首席研究员（PI）试图解决在前一个太阳周期中被认为值得特别关注的太阳物理学问题：在从伽马和x射线到红外和无线电波的广泛波长范围内对太阳活动进行协调观测。PI建议将重点放在太阳微波观测上，这在全色方法中是相对较新的。特别地，PI建议使用并扩展欧文斯谷的频率敏捷干涉仪，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学研究太阳活动。利用该干涉仪的观测可以准确地确定活动区磁场的强度和分布，并对耀斑加速过程中高能电子的热分布和非热分布进行定位和参数化。

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.
