LHC Timing Signal Distribution and Beam Phase Monitoring Through ATLAS   BPTX Monitoring System
  The LHC timing signals are broadcast to various destinations in the subsequent experiments. And all of them could be delayed to time in the ATLAS sub-detectors by using the Corde board and the RF2TTC module. The ATLAS BPTX detectors and monitoring system could guarantee the demanded sychronization of the beam in the futher collision.
