Abstract	The reconstruction of particle trajectories makes it possible to distinguish between different types of charged particles. In the era of particle colliders and high luminosities, this was one of the key aspects for the discovery of many new particles, lately the Higgs-boson. In high-energy physics, where trajectories are rather long. large size trackers muste be used to achieve sufficient position resolution. This is not the case in low-energy particle physics experiments, where particle trajectories are very short. With current position-sensitive detection technologies it is difficult to obtain sufficient position resolution for particle identification in large sensitive volumes since all these detectors are based on the read-out of the ionization signal. This limitation is due to the diffusion of the drifting electrons. In this paper we demonstrate a "proof-of-principle" experiment for a new method for the tracking of charged particles. It takes advantage of the scintillation signal which is not affected by diffusion while propagating through the sensor. With our setup we achieved a position resolution of about 28 \textmu m in the best case
