Description

In order to measure the orientation of the spectator reaction plane, the CMS Zero-Degree Calorimeters (ZDCs) are augmented with two 4x4 hodoscopes of quartz tiles, called the Spectator Reaction Plane Detectors. To reduce electronic noise the signals are digitized in the tunnel, very close to the detectors, which sit at zero degrees, 140m from the interaction point. The performance of the detectors in the recent PbPb run will be presented and the angular resolution in data will be compared to that found in GEANT simulations.
