Agenda
- Announcements
- Installation work:
- Mirror studies:
- Mirrors in OB determined to be UV-enhanced first surface mirrors which are different from those used in test sample studies
- Strongback disassembly and mirror reflectivity measurements Reflectivity Report (Bill)
- Tests of composition from oxidized surfaces (Eugene/Bill)
- 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
- Mirror studies:
- Spring 2019 DIRC Commissioning Analysis (All)
- Commissioning LUT analyses (All)
- Cherenkov ring fit (Roman)
- Cherenkov Systematics Survey Corrections (Ahmed)
- Commissioning FastDIRC update (Yunjie)
- Contributions to Jerry's DIRC review article (Yunjie, All)
- Commissioning LUT analyses (All)
- Software/simulations
- FastDIRC geometry implementation and alignment work (Cris/Yunjie)
- Software overview and tasks (All)
- AOB
