A large volume TPC is a leading candidate for the central tracking detector at a future high energy linear collider. To improve the resolution a new readout based on micro-pattern gas detectors is being developed. Measurements of the spatial resolution of cosmic-ray tracks in a GEM TPC are presented. We find that the resolution suffers if the readout pads(More)

The Gas Electron Multiplier (GEM) is a leading candidate for the readout of the Time Projection Chamber (TPC) at a future linear collider detector. This presentation describes measurements of the space point resolution of a GEM with relatively large hexagonal pads. Resolution of approximately 50 µm is achieved for 4.5 keV x-rays with two independent(More)
