RADIOACTIVE SOURCE CALIBRATION TECHNIQUE FOR THE CMS HADRON CALORIMETER
E. Hazen et al., Nuclear Instruments and Methods A

Abstract

Relative calibration of the scintillator tiles used in the hadronic calorimeter for the Compact Muon Solenoid detector at the CERN Large Hadron Collider is established and maintained using a radioactive source technique. The unique measurement technique described here makes use of the normal high-speed data acquisition system required for signal digitization at the 40 MHz collider frequency. The data paths for collider measurements and source measurements are then identical, and systematic uncertainties associated with having different signal paths are avoided.
