For the moment, you can find in this wiki documentation relative to the CERN timing chain.
You can start with:
Time transfer techniques between CERN and LNGS
We have divided the timing in four elements.
The GPS link, that has been calibrated by METAS and PTB
The Central Control Room to the Hall HCA442
Some useful abbreviations:
- BCT, Beam Current Transformer
- CCR, Cern's Control Room.
- cfc-ccr-ctpps, The front end (a PC running SC5 linux) where we have installed the CTRI that logs the PPS coming from the PolarRx2e
- cfc-hca4-saos12. The front end where we do the BCT logging, it has a CTRI and a DC110.
- CS4000, A cesium clock by symmetricom
- CTRI, control timing receiver, PCI format
- CTSYN, Takes the 10MHz and PPS from the XLi and regenerates a 40MHz and a PPS
- DC110, Acquiris Scope
- HCA442, It is the hall where we have the CTRI tagging and the extraction kicker pulse and the DC110 logging the BCT signal.
- PolarRx2e, A Septentrio timing GPS receiver
- SPS, Super Proton Synchroton
- XLi, A symmetricom GPS receiver
