Abstract
A drift chamber tracking system was developed and flown as part of the IMAX balloon-borne magnetic spectrometer. The drift chamber uses a he xagonal drift-cell structure and is filled with pure CO2 gas. It opera ted with high efficiency in the strong and inhomogenous field of a sup erconducting magnet, demonstrating a spatial resolution of better than 100 mum over most of the drift path for singly charged particles, as well as for helium and lithium nuclei. The drift chamber portion of th e spectrometer achieved a maximum detectable rigidity of 175 and 250 G V/c for protons and helium respectively.
