We had a brief meeting...

Start Counter Status

Lei gave us a report:

  • New scintillators from Eljen just arrived. There are 5 pieces, 60 cm x 15 mm x 3 mm, appropriate for a 30 paddle configuration.
  • Eric Pooser has started looking at a new amplifer that should have higher bandwidth than the one they were using before.

Sasha mentioned that he is planning to work with Vitaly Barutin, who is working on the CLAS12 central TOF, to charactize time resolution for the Hamamatsu SiPM's. Vitaly has a set-up in the EEL at JLab that is suitable for the study.
