Scientific paper

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.
