Video Conferencing Information

Meeting Time: 11:00 a.m. EDT

  1. To join via a Web Browser, go to the page [1] https://bluejeans.com/907185247.
  2. To join via Polycom room system go to the IP Address: (bjn.vc) and enter the meeting ID: 907185247.
  3. To join via phone, use one of the following numbers and the Conference ID: 907185247.
    • US or Canada: +1 408 740 7256 or
    • US or Canada: +1 888 240 2560
  4. Upon connection all microphones are automatically muted. To unmute your mike on a Polycom or equivalent unit, enter *4. Unmuting on a computer is trivial as there is a microphone button than can be clicked.
  5. More information on connecting to bluejeans is available.

  1. BCAL Reconstruction Issues
  2. BCAL Reconstruction Algorithms
  3. Will's reconstructed energy info

Action Items

  1. Make some plots that clarify the need for implementation of "shower curvature" information into the reconstruction.
  2. Determine up/down gain ratios for spring data (Mark)
  1. High priority items
    1. BCAL and FCAL z coordinates: some are referenced to the center of the target, not the global coordinate system.
  2. Low priority items
    1. z-coordinate determination from up/down amplitude ratio
    2. Sampling fraction tables
    3. Code Cleanup


  1. Announcements
  2. Action Items
  3. Commissioning Efforts
    1. Effective Velocities and Time Offsets (George)

    3. Layer efficiencies (Ahmed) [3]
    4. DigiHits wrap up (Tegan)
  4. Reconstruction
    1. Update (Will M.) [4]
  5. Simulations
  6. Any other business
