Title: Chromospheric response to non-thermal electrons generated during flare using RHESSI and SOHO/CDS Authors: R. O. Milligan, P. T. Gallagher, M. Mathioudakis, and F. P. Keenan Abstract: We propose to study the atmospheric response to non-thermal electron accelerated during solar flares using RHESSI and SOHO/CDS. By analyzing the hard x-ray spectra of loop footpoints with RHESSI, we can obtain information about the energy being deposited in the chromosphere and transition region. Using the diagnostic capabilities of CDS, the response velocities of the plasma can be obtained over a wide range of temperatures.
