BI/TB on LHC/SPS BST systems

Europe/Zurich
866 2-D05 (CERN)

866 2-D05

CERN

JJ Savioz:

- Issues related to latency for SPS BST transmission of injection and extraction prepulses means we need to use copper cables

- The PLL capture range on thr SPS Master does not allow covering the injection plateau for ion beams in the SPS 

- Timing jitter of 1nsec would be adequate/acceptable on the clocks

- Possible redesign of SPS BST message?

Javier:

- First-line responsibility for BST master systems to be clarified

- Follow-up for BST consolidation (LS2) to be made once the injectors and the LHC have started 

Heiko:

- Frev changes by 10% for protons in the PS and by *2.7 for ions!

- TFID RF train valid 15->20 msec before extraction - J. Emery hs requested a cable to BWS acquisition rack (could also be done by RF and BI)

- Some question of PLL Lock to be tested by BI
