Review of last minutes from the last meeting

We reviewed the meeting from the October 1st meeting.

  • All 8 PMT's from Hamamatsu have arrived at FSU and seem to work
    • The gain of these six slightly less than first two that were received: 2.5-3.5×106
  • The splitters Fernando sent to FSU have arrived

Target

  • Refrigerator. We discussed the status of the target refrigerator purchase. There is still a question of whether the refrigerator identified will be sufficient to support a helium target. Chris should be able to turn his attention to this soon, as was his plan. We need to review schedule and target in any case.
  • UMass-JLab MOU. Rory plans to be able to focus on this after the PrimEx run, which is in progress. The UMass responsibilities are in two parts: the target and electronics testing. One undergraduate has already been hired to help with testing, another one will be hired. The plan is to have the students spend time at JLab with Fernando Barbosa to learn the testing procedure and then transfer it to UMass.

Time-of-Flight

Sasha gave a status report on progress at FSU:

  • There is some money to equip the TOF production lab; purchases to outfit lab have started.
  • Paul is having some difficulties with 3M buying ESR material in sheet; he continues to work on it.
  • Three-counter/six-tube testing configuration is up and running.
    • Some mysteries:
      • High incidence of missing TDC and/or ADC's for good trigger.
      • Overflow bits being set in syncronous mode more often than expected.

Status of the MOU

The FSU-JLab MOU is being reviewed by Allison Lung. The step after that is to pass it through the concurrence chain at the Lab.
