EAM and AFT integration meeting - EN-EL workflow proposals

Wednesday 4 Jun 2025, 15:00 → 16:00 Europe/Zurich

112/4-B60 - EN-IM Meeting Room (CERN)

Main points:

• EN-EL proposal for AFT/EAM workflow and PMU data handling
  • no-PMU case:
    • EAM 'event' created and linked to AFT (up to N)
    • compatible with proposed linking plug-in (EAM 'event' linked to AFT), except that it would need extension to write data to AFT and mark fault as reviewed.
    • for minor events, approach works without AFT link (dealt with between TIOC and EL EAM)
  • PMU case:
    • PMUs to automatically create EAM log (type: perturbation)
    • 'perturbation' linked to 'event' as first approach; 'event' linked to AFT by EL
    • data analysis requires fetching combined data from AFT & EAM
      • on AFT side, data (including EAM links) can be extracted via API or GUI
      • on EAM side, data (including AFT links) should be possible to extract
      • merging of data via links possible
• Discussion
  • Serge reinforced that merged events across accelerators would be very useful
  • Lukas asked whether EL wants to keep EAM creation and linking manual; otherwise PMU data may be read out by AFT automatic fault recording, to create and populate AFT fault automatically and then populate EAM
    • figured that for minor events this may not be useful
  • EL and EAM will check feasibility of automatic EAM log creation from PMU data
• Agreed that RAWG will work out combined proposal taking inputs from TIOC, EL, CV
