Abstract
A Time Projection Chamber with a maximum drift distance of 26 cm was equipped with a triple GEM and a high resolution pixel readout. This detector was set up in a cosmic ray test-stand and 40 000 tracks have been recorded. It was shown, that the transverse spatial resolution in dependence on the drift distance was close to the diffusion limit of single electrons. In an electron test beam with an energy of 0.5 GeV it could be demonstrated that the data show no significant dependence on the track inclination within the pad plane.
