Modelling Langmuir Wave Interaction with Plasma Inhomogeneities in the Flaring Solar Corona
Abstract
We present simulations of the time and spatial evolution of electron beam driven Langmuir wave turbulence interacting with plasma inhomogeneities. This code can be used to investigate a variety of particle acceleration and propagation scenarios in the flaring corona and interplanetary space. Here we present one simple model: simulations of a beam of accelerated electrons propagating from an acceleration region at the top of a coronal loop down to the chromosphere. RHESSI imaging spectroscopy shows a flatter X-ray spectrum at the footpoints compared to coronal sources, so we investigate whether plasma waves and inhomogeneities can change the electron distribution in such a way.
