The CMS hadron calorimeter detector control system upgrade

摘要

The detector control system of the CMS hadron calorimeter provides the 40.0788 MHz LHC clock to the front end electronics and supplies synchronization signals and I2C communication. Pedestals and diagnostic bits are controlled, and temperatures and voltages are read out. SIPM temperatures are actively stabilized by temperature readback and generation of correction voltages to drive the Peltier regulation system. Overall control and interfacing to databases and experimental DAQ software is provided by the software CCM Server. We report on design and development status, and implementation schedule of this system.
