    "abstract": "A novel charged particle tracking device, a high precision time projection\nchamber with gas electron multiplier and pad readout, is a leading candidate as\nthe central tracker for an experiment at the International Linear Collider. To\ncharacterize the performance of such a system, a small TPC has been operated\nwithin a magnetic field, measuring cosmic-ray and laser tracks. Good tracking\nresolution and two particle separation, sufficient for a large scale ILC\ncentral tracker, are achieved.",
