The first part of the meeting was dedicated to the results of the BISv2 SPS model. In the discussion, it was established that:

• There are no CIBFx cards in the SPS Ring, but Extraction to LHC BIS will have more of them.
• SPS pre-op checks will only be run from time to time as they are not included in the sequence - otherwise they would run too often and risk compromising availability (for instance, due to database connection problems, etc.). 
• The annual test will not check every user.
  • However, all CIBUs will be tested in test mode that does detect all CIBU blind failures identified in FMECA.
  • Some users test every year, e.g. vacuum, BIC, MP checklist.
  • Recommendation: have users trigger more often:
    • also upon every change.
• Action: complete a sensitivity analysis on increased failure rates and/or increased testing intervals.
• Action: model SPS to LHC transfer line:
  • master and slave BIC,
    • master to kicker is optical loop,
  • has many concentrators.

The second part of the meeting focused on the BISv1 failure analysis leading to establishing failure rates based on field experience with that system.

AOB:

• Timing error last weekend:
  • Timing mismatch between LHC and SPS timing following restart of LHC timing.
• Prevented injections, did a dry dump. Apparently first noticed by Ivan and then by OP
