Energetic events in the solar corona accelerate charged particles, resulting in phenomena such as coronal mass ejections (CMEs) and hard X-ray flare footpoints. Several acceleration and energy transport mechanisms have been proposed which need to be tested with simulations. We will write a high order particle acceleration code that uses magnetic and electric fields interpolated from an MHD simulation. The code will be tested by attempting to replicate the motion of charged particles in a flat current sheet solved analytically by Speiser (1965). Our main goal will be to use this code to simulate particle acceleration near 3D magnetic reconnection sites in the corona.
