  1. LHC Machine Check-Out andBeam InstrumentationBI LHC TB – 22/05/08 The Dashboard The Working Conditions The Common Chapters State What’s Next.

  2. The Dashboard … BI HW Domain BI SW Domain Other Commissioners (ABP/CO/OP) Domain • You’ll find there the Dashboard

  3. The Dashboard … • The Dashboard Color Schema – The week number given in the table tells when we expect to be ready for commissioner tests.

  4. The people involved

  5. External Commissioner’s Roles

  6. The General Working Conditions • BI front end acquisition are triggered via the different following ways: • General central timing events like pps for regular acquisitions (i.e. logging, fixed displays, FB loops…) • Injection prepulses • General machine events like injection, beam dumped, post mortem events (for IPOC, XPOC and PM buffers) • Dedicated events like BLM, BCT, BPM, BSRT captures or BWS, BQ triggers • Continuous loop when no specific sync is required.

  7. The General Working Conditions • For systems with turn or bunch resolution, some of these events (prepulses, capture/PM events…) are forwarded by the BOB (LHC fast timing system) to insure these systems will trig on the same expected turn. • Today, the BOB infrastructure is configured and capable to retransmit these events to our front ends. • To fully test systems like BLM or BSRA, we also need the energy to be transmitted through the GMT and regularly modulated from 450 GeV to 7 TeV.

  8. The General Working Conditions • So all we need to test our systems acquisitions is the regular transmission of these timing events on the GMT plus a modulation of the transmitted energy. • We discussed with the other equipment group to put in place such a sequence of events that we could run on a regular basis and that could satisfy everybody. • The result was a sequence of events, simulating series of fill (ie, injections and dumps at different energy) covering a full day. During each fill, in addition to the standard injections, start/stop ramp and beam dumped events, we will have BI capture events every 20 sec. The energy information will also be transmitted through the timing.

  9. The General Working Conditions • The proposed sequence of fill looked like this. • Unfortunately, we can not play this anymore until the repair and re-commissionning of the diluter kickers, active member of the energy transmission loop. • We hope to have this back around week 23. • In the mean time, an simple event sequence has been build that will run the events we are interested in (except PM events) on a regular bases with a fixed energy of 7648 GeV = Error. • This table is currently running

  10. The General Working Conditions

  11. The Dashboard XPOC Column • Most BI XPOC interfaces have been agreed and implemented. • They are already currently tested by Verena during dedicated dry runs. • We now expect Verena’s feedback until she eventually declares these chapters ready for beam.

  12. The Dashboard PM Column • Most BI PM interfaces have been agreed with CO and documented. • BLM PM buffer transmission is currently tested by CO (M Zerlauth, N Trofimov) during dedicated dry runs. • We plan to have BPM and BCT PM buffers ready for test by mid of June. • M. Zerlauth gives us regular feedback and will eventually declare these chapters ready on the ‘technical’ side. • But somebody should also review the content of these buffers

  13. The Dashboard SetMan Column • The LSA setting management DB is currently re-designed. • The tool (extended ‘Acquire Settings’) proposed by Greg will cover our needs. Some minor missing features will be added in the coming days. • We will create an LHC ‘HW Group’ for every BI observable (intensity, position, transv. profiles, long. profiles, losses, tune, luminosity) and manage our archives via this tool. • Some commissioners will participate to see if there is a need for extra operational settings storage and how to handle them.

  14. The Dashboard RBAC Column… • We currently wait for the RBAC config tool to be finalized by AB/CO. The new expected features are: - the option to create and use device and property groups - the option to use a basic machine mode, i.e. OPERATIONAL, NOT-OPERATIONAL. • This is now foreseen to only be operational end of June! • BI plans for RBAC can be consulted in here • I’ll insist on the fact that non RBAC-aware applications will lose connection with RBAC-aware FESA servers.

  15. The Dashboard Logging Column … • The commissioning infrastructure has been agreed with AB/CO/DM and is ready. • BLM logging is ongoing. • We will discuss and define the logging of the other systems in the coming weeks with the commissioners in charge and implement it. • This should be practically finished by the end of June. • We’ll start with BRANA, BRANB, BWS, BSRA, BSRTS this week.

  16. The Dashboard FixDisp Column… • Alarms: • BI alarms will be discussed and agreed with Markus • BI Video Transmissions: • In progress: Full list in here. • OP commissioners will follow this UP. • CO ‘standard’ fixed displays (if any): • Jakub (CO) should configure them and give us feedback • We’ll have a LOT of standard/non standard FD. Somebody will have to think about it…

  17. The Dashboard OPGUI Column… • We are currently collecting every BI related applications on the LIDS (our SW portal) to give a simple and coherent access to these applications for our commissioners. • We have to give our commissioners the possibility to easily work from their main working place, at least till the LHC start-up.  

  18. The Dashboard OPGUI Column… • For all CO/OP commissioners, there is no issue. Their PC is most probably correctly configured or they can work from CCC. • For ABP commissioners (mainly in Meyrin with non configured/trusted machines), we have to propose a solution. •  One option could be to open namely our future (foreseen mid June) BI terminal server cluster to our ABP commissioners (and only them), i.e.: J. Jowett, H. Burkhardt, M Giovannozzi, S Gilardoni, W Herr, C Carli, R Assmann, F Zimmermann, G. Arduini et toi. •  We’ll discuss this with CO. They have maybe something already foreseen for these cases.

  19. Instrument Status • See dedicated Wiki

  20. What’s next? • Instrument dedicated meetings to: • Present available tools and list missing features: • fixed displays • OP GUI • expert GUI • test programs • Ad hoc meetings triggered by the pilot to: • Feedback • Prepare tests • Regular status update on Wiki by the pilot (see updates) • The mini team mailing list and the issue tracking tool are also available.
