Kinetic Simulations of electron energization in global scale poloidal Alfven waves

Electron signatures associated with kinetic ballooning instability small scale azimuthal structures in optical signatures associated with low frequency wave activity have been observed around the time of substorm onset and the characteristic frequency and kinetic scale structures have been attributed to the onset of a kinetic ballooning instability. To this end, we have advanced a hybrid gyrofluid kinetic electron model to include consideration of poloidal Alfven modes (which is a necessary step toward addressing ballooning) and compare these model results with studies of toroidal field line resonances done previously. Initial work on the inclusion of a ballooning drive term in the model will also be summarized.
