JLab: TEDF, Room 2561b
BlueJeans: 350 531 998


  1. Announcements
  2. Review of minutes from the last meeting
  3. Detector Status
  4. Software Issues
  5. TOF NIM paper
  6. Action Item Recap



  • FSU: Edmundo Barriga
  • JLab: Mark Ito, Sasha Ostrovidov, Beni Zihlmann


Beni reported on the calibration of the current run.

  • The code works now with the new geometry.
  • He has gone through the steps of the procedure multiple times.
  • There still may be some checks to do on the code.
  • The walk correction is key: without a good walk correction subsequent steps are useless.
  • A reconstruction job using the new constants was tried. Pions greater than 1.0 GeV/c are required to match TOF points to within 13 cm in x and y. Many histograms are empty, some only partially filled. This is work in progress.

NIM Paper

Sasha reports that work continues on the NIM paper, though not at a blazing fast pace. Further discussion is needed.
