First Results from New High Magnetic Field Measurements with the MediTPC Prototype
In the ILD concept, a TPC is foreseen as the main tracking device. The MediTPC prototype has been developed at DESY to study the properties of Gas Electron Multipliers (GEMs) and to perform resolution studies. Studies of the influence of oxygen contaminations on the electron signal are presented here. Further, resolution results with new pad planes with 1.27x7.0 sqmm pad pitch and in high magnetic fields are shown.
