Organization

  • Time: 4 pm EST
  • Connecting: detailed instructions are here
  • Conference id: 536076821

Action Items

  • Send Todd a geometry of tagger area, including the mapped tagger magnet field, for GEANT simulations (Richard). Sasha defined geometry, Richard will add field map
    • Sasha needs to update geometry with girder.
    • Richard has not had time to add Dan's new field. For now use the old field.
  • Estimate rates and ranges of parameters needed for the photon beam tuning (Todd for accelerator; Elton, Hovanes, Eugene, Alexandre for Hall D)
    • Need rates for profiler, start counter, ps

Agenda

  1. Announcements
  2. Recommendations from ERR Report
    • Notes beyond ongoing efforts:
    • p2 5b) "...strong suggestion by the committee to install several beam loss monitors inside Hall D proper"
    • p5 third paragraph proposes "The installation of a few sacrificial SiPMs in the Tagger hodoscope during the remaining beam transport commissioning activities, at the start of the next beam operations period..."
    • p7 first bullet: "Setup and tuning of photon beam into the experimental area along with monitoring of background and radiation levels. The latter has to be continuously available and cannot rely on the start of the DAQ system."
    • p8 under slow controls: "...concerned about... the motor control commissioning... Specific recommendation: Implement limit switches and/or hardware to avoid movable collimator completely out."
  3. Debrief Aug 8 Review:
  4. Electron Beam Specifications
    • Need signed document?
    • Accelerator and Hall D Interface Document - needs to be finalized.
  5. Update on Electron Commissioning (Todd/Mike)
    • Monitoring of photon beam dump?
    • Populating Operational Restrictions [1]
  6. Update on Photon Commissioning (Alexandre)
    • Version for the ARR
  7. Update Radiation monitors and controls (George/Pavel)
  8. Other business
