Agenda

  1. Announcements:
  2. Issues and monitoring with the ongoing run:
    • LED trigger monitoring: [2]
      • Per pion/kaon track photon yield monitoring will be available soon.
      • Many items in item #4 can be monitored using the same platform.
    • DIRC South Lower Box LV Group 9 trip during Start/Stop Run.
    • Tile temperature/communication error: three time per week. [3]
