Video Conferencing Information

Meeting Time: 11:00 a.m. Eastern

  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: 199.48.152.152 (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.

Attendees: Manuel, Zach, Shayne, Laura, Yi, Mark, David, Elton (JLab); Zisis, Tegan (UofR); Christina, Stratos, George (Athens)

  1. Announcements
    • Users Meeting this week. Elton has also been elected as a member at large of the UGBOD.
  2. Action Items
  3. FCAL (Manuel)
    • HDFCAL log book
    • Overnight runs completed for LED and cosmic triggers
    • Checking the stability of environmental monitors, temperature, humidity and light. See the 3 hour temperature cycle seen with BCAL
    • Investigation of individual channels that do not stabilize
    • Cosmic trigger. Overflows seen in about 1% of the triggers
    • LED and cosmic-ray data will be used to check normalization of gains. The LED data will be used to smooth out behavior between neighbors. The cosmic-ray data will be investigated for use to equalize response.
    • Zach: The FCAL has spare environmental monitoring channels that could be used to record temperature and humidity outside the darkbox. He was encouraged to work with Dave Butler to add these to the system.
    • Andrei: Asked about an apparent "reflection" in the pulse shape from a cosmic-ray. It does not seem to be a reflection, as it is not seen with LED data.
  4. BCAL
  5. HDBCAL log book
  6. Mark showed preliminary results of the cosmic-ray data. The integral and max values were plotted.
    • The inner layer shows a peak at the expected energy deposition of minimum ionizing tracks. This corresponds to about 22 MeV for the peak and 230 samples for the integral -> integral counts * 0.1 ~ MeV
  7. Elton summarized work with the LEDs
    • Data have been taken overnight with the pulser at 12, 18 and 24 degrees
    • Learned how to operate the chiller during this time. It is now maintaining the temperature very stable, within o.1 deg C.
  8. Reconstruction and Simulation
  9. D3 update
  10. Calibration
  11. Any other business
