To characterize the performance of such a system, a small TPC has been operated within a magnetic field, measuring cosmic-ray and laser tracks. Good tracking resolution and two particle separation, sufficient for a large scale ILC central tracker, are achieved.26 pages, 13 figures, submitted to Nuclear Instruments and Methods AInstrumentation and Detectorstext
