Abstract :
The calorimeter trigger synchronization of the Compact Muon Solenoid experiment at the large hadron collider (LHC) is presented. The synchronization method is implemented in the synchronization and link board (SLB). The board allows the synchronization of electromagnetic and hadronic trigger primitives at the LHC frequency (40.08 MHz) and its transmission to the Regional Calorimeter Trigger using electrical links at a rate of 1.2 Gb s−1. The system developed for the SLB tests and the commissioning of the full production (1210 boards) is also presented.
