Description

This paper reports on the tracking performance of the ALEPH Time Projection Chamber (TPC) studied using the data taken during the LEP running periods in 1989 and 1990. After careful correction of residual distortions and optimization of coordinate reconstruction algorithms a single coordinate resolution of 173 μm in azimuthal and 740 μm in longitudinal direction is achieved. This results in a momentum resolution for the TPC alone of Δp/p2 = 0.0012 (GeV/c)-1. In combination with the ALEPH Inner Tracking Chamber (ITC) a total momentum resolution of Δp/p2 = 0.0008 (GeV/c)-1, close to the design specifications is reached
