The PI will perform collaborative observations of the Sun with the Russian RATAN 600 and the Very Large Array (VLA) in the US. He will combine the high spatial and temporal resolution of the VLA with the broad spectral coverage and accurate polarization data of RATAN one- or two-dimensional scans for information on the magnetic fields' structure and strength in the corona, as well as the temperature and electron density in different plasma structures. He will also localize regions of thermal and nonthermal energy release with these combined data sets. Finally, he will determine the three-dimensional temperature, density and magnetic structure of intense, slowly-varying coronal regions controlled by coronal magnetic fields and electric currents. These developments will all provide new insights to the emission, heating and acceleration mechanisms of particles trapped within the magnetospheres of solar active regions.

PI将与俄罗斯的RATAN 600和美国的甚大阵列（VLA）合作观测太阳。 他将联合收割机的高空间和时间分辨率的VLA与广泛的光谱覆盖范围和准确的极化数据的RATAN一维或二维扫描的信息磁场的结构和强度在日冕，以及温度和电子密度在不同的等离子体结构。 他还将使用这些组合数据集定位热能和非热能释放的区域。 最后，他将确定由日冕磁场和电流控制的强烈、缓慢变化的日冕区域的三维温度、密度和磁结构。 这些进展都将为太阳活动区磁层内捕获的粒子的发射，加热和加速机制提供新的见解。
