    "abstract": "A large volume Time Projection Chamber (TPC) is being considered for the\ncentral charged particle tracker for the detector for the proposed\nInternational Linear Collider (ILC). To meet the ILC-TPC spatial resolution\nchallenge of ~100 microns with a manageable number of readout pads and channels\nof electronics, Micro Pattern Gas Detectors (MPGD) are being developed which\ncould use pads comparable in width to the proportional-wire/cathode-pad TPC. We\nhave built a prototype GEM readout TPC with 2 mm x 6 mm pads using the new\nconcept of charge dispersion in MPGDs with a resistive anode. The dependence of\ntransverse resolution on the drift distance has been measured for small angle\ntracks in cosmic ray tests without a magnetic field for Ar/CO2 (90:10). The\nGEM-TPC resolution with charge dispersion readout is significantly better than\nprevious measurements carried out with conventional direct charge readout\ntechniques.",
