Review of minutes from the previous meeting

Sasha put together a guide to running the TOF DAQ] in stand-alone mode, as requested at the last meeting.

Collaboration Meeting February 18-20, 2016

Mark will pencil in Sasha's name on the agenda.

Calibration Status FSU

Sasha is looking at cosmic data. The chi-square for the fits are anomalous. He is looking into it.

Run Readiness

  • HV scan Sasha put together a definite proposal for the scan and sent it along to Alexandre Deur. It emphasizes voltages lower than the present nominal settings since we would like to see if we can run at reduced current to extend PMT life. If time is short we can cut the list a bit shorter.
  • TDC delay parameter scan: Beni has finished taking and analyzing the data. It remains to transmit the values to the offline group for downloading to the TDCs.

NIM paper

Beni will get in contact with Paul. He would like to set a deadline for having a draft paper. Mark also mentioned that there is TOF section in the TDR that probably needs re-write.
