The XENON Dark Matter Experiment utilizes ultra-pure xenon (Xe) as a target for particle interaction in the effort to detect dark matter particles. To measure the purity of Xe, a gas purity monitor (GPM) is being developed which drifts electrons through Xe gas to detect impurities that contribute to charge attenuation. An axially-symmetric model is used to simulate the electric field generated by boundary electric potential boundary conditions. Electrons are then traced through this field, subject to an additional drag force. The electron trajectories can be used to tune geometric parameters in an effort to ensure adequate GPM performance. This simulation process is crucial to finalizing the GPM design, allowing construction and testing of the GPM to begin.
