For the moment, you can find 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
- Central Control Room to Hall HCA442
- CTRI to Scope
- BCT to Scope
Some useful abbreviations:
- BCT, Beam Current Transformer
- CCR, CERNS'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
