Description

The Cosmic Rack (C-Rack) is an essential component of the CMS High-Luminosity LHC (HL-LHC) upgrade at CERN. Designed to test 2S modules and validate the Tracker Integration workflow, the C-Rack trigger system utilizes a scintillator and photomultiplier tube (PMT) setup with cosmic rays as the particle source. This poster presents the commissioning and calibration results of the scintillator-PMT system. In addition to generating the required trigger signal, the system also offers the capability to locate particle hits within the scintillator.
