Performance of the CMS cathode strip chambers with cosmic rays


CMS Collaboration; Amsler, C (2010). Performance of the CMS cathode strip chambers with cosmic rays. Journal of Instrumentation, 5(3):T03018.

Abstract

The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47μm to 243μm. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns.
