Matters arising and actions:

• ISTs during weeks 34 and 35 is still under discussion --> Etienne is in contact with David. This planing should be finalized soon - once that is clarified we need to response on the phases of the final dump assembly so that this can be finalized.
• ALPS test had to be moved to BA6 as there is not power in BA3 during this week - to be taken into consideration in the future.

Agenda:

• News on dry-run and test progress (K. Li)
  • FESA classes for FGCs - to be checked; in simulation mode we can have a test; should arrive around 15 February
  • ALPS has already been well tested by Stephane in BA3
  • ALPS interlocks needs to be checked early together with Yannick!

• RF frequency programs and frequency distribution during slip stacking (T. Argyropoulos)
  • For FFA all frequencies can be distributed and it is up to the client to decide what frequency they want to see.
  • All RF frequency programs are distributed also during slip stacking; again, it is the client that is free to decide what frequency program is to be used.
  • Verena commented that the BST needs to choose one frequency as synchronous; this needs to be done at the start of the cycle. (ACTION: To be checked early next week - Giulia to check with RF on possibilities and then schedule a meeting; Etienne also remarked that the TSU would need to work correctly with the frequency swings. Verena said it would be good to then come up with a list of which clients would use which frequency.)

• Impact of name changes of FGCs (S Cettour Cave)
  • Stephane showed the name PC changes
  • The name changes should be simple to implement both for imported as well as for the virtual parameters
  • Verena asked about generation or makreules using logicals - this always works via ID so there is no problem here
  • Loic stressed that the name changes should be done soon and complete the table; Stephane will check with David Nisbeth (ACTION: Stephane to forward the tables and get in touch with David)

• SIS: Exporter from TT10 BIC (E. Veyrunes)
  • External condition should inhibit the injection kicker from pulsing - Verena asked whether it is okay that the injection kickers keep pulsing; there was a small discussion for reasons to turn of kicker pulsing. It was decided to use AllUserPermitted in the SIS - it can still be modified or masked, or changed in case there is an issue. In any case the MDSH will not pulse.
  • An MKP enable input has been added; this will be on the master BIC close to the PS; this also gives operational flexibility as it is not done via timing
  • Ivan mentioned that there is already an input; in this case however the MDSH would be going as well, so it can not be done like this --> Brennan asked this to be put down in a could of pages that can be summarize with explanation and all use cases which can then be circulated (ACTION: Verena, Eric compile a small summary with use cases and circulate this)

• A proposal for improving the MDSH.11971 interlocking (I. Ramirez)
  • Ivan reminded about the new SPS injection interlock system
  • Ivan made a porposal oj the ay the MDSH interlock circuit is done: a WIC on MDSH will not have an impact on the beam; instead, the MDSH powering interlock can be moved from the Ring-WIC to the TT10-WIC
  • Ivan asked about how to manage extractions - this would also need to be discussed in detail; there are several options; Brennan again stressed, that this should become part of the above mentioned document.
  • If the proposal is accepted, there would need to be some changes to be implemented.
  • There are no modification on the power converter side. The proposal was accepted - Verena asked to go on with the modification.

• Status of SPS beam line activities (A. Grande Mallavia)
  • Some delay has been accumulated; Antonio is searching for way to catch up with the delay.
  • Vacuum has been delayed as the cabling it not yet entirely finished. A machine is considered closed when it is pumped.
  • Brennan asked whether the question on the drains has an impact - Etienne said that they will still need to decide what to do with the drains; this need to be followed up (ACTION: Etienne to decide what to do with the broken drains)
  • Brennan asked Lars to check on the WS issues (ACTION: Lars to investigate problems with WS, detail or major?)
  • Antonio's list comprises only what had been refurbished and needs tests before being installed.

• Round table:
  • Brennan asked for a couple of slides on status of the layout database for next week
  • Etienne: details of planning changes? For Etienne still to early before dat from EN-STI

• AOB:

• Next meeting:
  • Dry run digest
  • Listing RF completeness further
  • IST checklists
  • How do clients deal with slip stacking?
