Present:

  • FIU: Werner Boeglin, Mahmoud Kamel
  • JLab: Eugene Chudakov, Mark Ito (chair), Eric Pooser, Thomas Britton

There is a recording of this meeting on the BlueJeans site. Use your JLab credentials to authenticate.

NIM/TDR

Eric reported on the status of the NIM paper.

  • Werner's edits have been implemented.
  • Now waiting for plots on attenuation and other performance parameters.
  • FIU guys will meet on next week to finalize the choice of plots to include.
  • New deadline for a draft: August 18.

Attenuation Update

Mahmoud reported in progress with the attenuation measurement.

  • Pion proton separation using start counter dE/dx is much improved with the both sets of attenuation corrections, those obtained on the bench at FIU and those obtained from data.
  • The fits to dE/dx distribution, as measured using pulse integral, are now converging for all sectors.
  • Fits to dE/dx as function of z are done in two regions and represent the data well.
  • The new constants obtained from data have been added to the CCDB, but there is currently some technical difficulty in modifying the PID library to use them. This is work in progress.
