Review of minutes from the April 11 meeting

We went over the minutes without significant comment.

Collaboration Meeting

To get word out about our thinking about a TOF upgrade, Beni will give a talk on the TOF in general in the Friday morning session. At least we put his name on the agenda.

Calibration Status

Beni gave the report.

  • The CCDB has been updated with work that he completed before the Workfest. This includes calibrations for the first half of 2018.
  • There are about 30 runs being calibrated now that there are sufficient ROOT files to do the job.
  • Performance of the reconstruction using the new constants has not been looked at yet.

Shipping Spare PMTs to JLab

The PMTs are ready to come back to the lab, but given our discussion of building more counters, we discussed leaving them at FSU. This needs further thought.
