The ACTAR TPC detector has been designed as a state-of-art detector for the tracking of ions in nuclear physics experiments. We performed various sets of test measurements with an alpha source, using a reduced size demonstrator of this device, in order to estimate the performances that can be expected from the tracks analysis. The parameters from the detector, from the electronics and from the analysis have been studied, with their influence on the energy resolution and the tracking precision. An effective full 3D charge distribution reconstruction method is also presented in order to analyze particle trajectories in any direction.
