Description
The International Large Detector (ILD) concept for the ILC plans to use a Time Projection Chamber (TPC) with Micro-Pattern Gas Detector (MPGD) readouts as its central tracking. A Micromegas readout module has been tested with a large ILC-TPC prototype operating within the EUDET facility at DESY. Measurements carried out within a 1T magnetic field, as well as with no magnetic field, allowed for the measurement of the transverse spatial resolution. A preliminary point resolution of 60 microns extrapolated at zero drift distance was obtained with the MPGD readout concept of charge spreading with a resistive anode. The homogeneity of the detector and possible distortions have also been studied. A plan in progress to fully cover the large prototype with 7 modules with integrated electronics will also be presented.
