DOROS follow-up

Thursday 11 Jul 2024, 15:00 → 16:00 Europe/Zurich

865/1-B03 (CERN)

• Previous meeting (21/05/2024)

  • Attendance

    • E. Balci, M. Gonzalez Berges, S. Jackson, M. Gasior, M. Dolenc, D. Alves

 

• •  Capture (mostly used by the OMC team)
    • Sw trigger
      • Working? Yes
    • Hw trigger
      • Working? Yes
    • There was a problem with the buffering mechanism
      • Manuel fixed it in the development version but the problem still exists in the deployed version
        • Update [11/07/2024]: still the case
  • Freeze (linked to "PM on-demand" functionality)
    • Sw trigger
      • Working? Yes
    • Hw (BST) trigger
      • Working?
        • Update [11/07/2024]: Manuel and Miha and Marek agreed that the BST capture and freeze are to be implemented as the same thing just configured with a different parameter
          • Ongoing effort (Miha + Manuek) debugging unexpected behavior - understood
          • Test to be done in the lab (using a signal generator) where 1 system is set to capture and the other set to freeze and validate that the data is continuous
  • Locking the gain during VdM scans
    • issue with event subscription to lumi server (Sat 18th May) has been fixed
    • proper fix should be done at the CCDE level, but either putting the subscription on one of the ordinary devices or having a script that makes sure that the on-subscription event is in the instance file could also be done as a temporary measure to guarantee the quality of the data for the experiments
      • Update [11/07/2024]: implemented in CCDE so, not an issue anymore
  • Update (11/07/2024): In one of the MDs in MD3 they want to use capture -> request is to have SDDS files to be analysed. Trigger has to be BST. Tested on the BI side for now but will be soon tested together with ABP
    • Update [11/07/2024]: Agreed to evaluate whether this version works and aim for deploying it for good during the next TS
  • Outlook for DOROS sw work
    • Quantify the RT performance of the FESA class
      • An idea would be to use Mathieu's python code which inspects (calculates statistics) the navigator's UDP diagnostics packets from the FESA class
        • Update [11/07/2024]: Elif will have to change Mathieu's python utility that uses FESA diagnostics to do an RT characterization of any FESA class
    • Chart present design and propose refurbishment
      • Update [11/07/2024]: Elif has started making UML diagrams of the DOROS class using a script of her own + DrawIO. Ongoing work.
