| Summary: | 6 % more multiwire events occurred in the module than was A drift chamber module with 5 anode wires covering an active atm. Modules will be used with the Multipole-Dipole- by other authors and the design of the drift chamber module drift chamber module are discussed and the performance of the drift chamber module is predicted based on the physics. Drift chamber modules were tested with 240 MeV a particles expected and/or the localization uncertainty due to the expected. expected. Trajectories were located to within 225 mm ︢5 / experimentally was larger than what was predicted. This in flight times of ionization electrons was larger than isobutane were sufficient to obtain high-resolution measurements using the drift chamber module even though up to mm (FWHM) at a pressure of 0.25 atm. The resolution measured Multipole Spectrometer in a-particle scattering experiments position of a-particle trajectories to within 295 mm full- presented here. Sources of localization uncertainty in the region of 9 cm x 76 cm has been built to locate the vertical several pressures. The operational characteristics of suggests that the localization uncertainty due to variations timing resolution of the electronics was larger than to discuss the operational characteristics of chambers built to measure vertical angles of trajectories needed for ray tracing. The physics of drift chambers is described and used using isobutane and an E/P ratio of 2000 V/(cm-atm) at width-half-maximum (FWEM) in isobutane at a pressure of 0.25 |
