Agenda

  1. Announcements
  2. Installation work:
    • Mirror studies:
    • Epoxy test samples to prevent corrosion of exposed aluminum surfaces (Tim, Bill, All)
    • Next steps:
      • Receive remaining UV enhanced mirror from Bates and have cut for additional sample pieces (Wednesday 7/24)
      • Decide on epoxy for pin holes of Upper (North) OB. Apply epoxy and re-install mirror box in OB for installation. After receiving gold-plated screws, install in upper bar boxes and proceed with installing North OB
      • Replace mirrors on Lower (South) mirror box, re-anodize strong back and reapply new mirrors. Need to choose the same UV-enhanced or other first surface mirrors from previous tests.
        • Tests of separating test mirrors from aluminum piece already underway
  3. Spring 2019 DIRC Commissioning Analysis (All)
  4. Software/simulations
    • FastDIRC geometry implementation and alignment work (Cris/Yunjie)
  5. Software overview and tasks (All)
  6. AOB
