Recent Results from the Cleo dE/dx System

The installation of the CLEO dE/dx particle identification system was completed last summer. DE/dx measurements are made with a pressurized gas proportional wire chamber system capable of making 117 ionization measurements. We report on measurements of relativistic rise and resolution from data taken on the T resonances and the nearby continuum. We describe the proven capabilities of the device in identifying hadrons in both the low and high momentum regions and electrons above 1 GeV/c.
