摘要In this paper we describe the operation and performance of the HERA-B Outer Tracker, a 112 674 channel system of planar drift tube layers. The performance of the HERA-B Outer Tracker system fullfilled all requirements for stable and efficient operation in a hadronic environment, thus confirming the adequacy of the honeycomb drift tube technology and of the front-end readout system. The detector was stably operated with a gas gain of 3 x 10(4) in an Ar/CF4/CO2 (65:35:5) gas mixture, yielding a good efficiency for triggering and track reconstruction, larger than 95% for tracks with momenta above 5 GeV/c. The hit resolution of the drift cells was 300-320 mu m and the relative momentum resolution can be described as: sigma(p)/p[%] = (1.61 +/- 0.02) + (0.0051 +/- 0.0006) . p[GeV/c]. At the end of the HERA-B running no aging effects in the Outer Tracker cells were observed. (C) 2007 Elsevier B.V. All rights reserved.
