  3. Action Items
  4. CPP and NPP Readiness Review
  5. Responses to the ERR. This link points to the draft response to the ERR.
    1. MWPCs (fabrication, testing) (Rory)
      • Good progress. Two more sections more.
      • Started stringing the 8th (last) MWPC last week, now that students are back on campus
      • Elton: We should create single-page summary of MWPC, as was done for all previous GlueX detector systems. See GlueX-doc-2376
    2. Trigger rates (beam test analysis, expectation with target pulled back) (Ilya)
      • Ilya presented new calculations showing that the rates increase by about 15% when the target is retracted from 65 cm (nominal GlueX) to 1 cm.
      • He continues to run MC studying the target dependence for the signal.
    3. Hdgeant4 (initial setup and plan for running simulations) (Beni)
      • Beni:
    4. Analysis (low level reconstruction, monitoring) (David to write paragraph)
