Abstract
This contribution investigates a prototype of a TPC readout with a highly pixelated CMOS ASIC, which is an option for charged particles tracking of the ILC. A triple GEM stack is joined with a TimePix and MediPix2 chip (pixel size of 55×55μm2) and its readout properties are investigated with 5 GeV electrons. The spatial resolution of reconstructed cluster centers is determined as a function of the drift distance for different gases and stack configurations. Also the drift velocities are extracted. A single point resolution down to ≈25μm is achieved for small drift distances.
