Chairman's Cell Phone




  • FSU: Paul Eugenio, Kurt Koetz, Sasha Ostrovidov, Randall Smith
  • JLab: Chuck Hutton, Mark Ito, Elton Smith, Tim Whitlatch, Beni Zihlmann


The proposal from FSU on the constuction constract has been through technical review and a report filed with JLab Procurement. The committee members were Beni, Dan Carman, Elton, Bruce Lenzer, and Mark. Eugene Chudakov was present at the review meeting. Mark has been, and will continue to, check on progress at Procurement.

PMT Purchase

The technical review committee has met and discussed proposals from vendors. A report is being prepared to send to Procurement. That should happen tomorrow.

Calibration and Alignment

Sasha has been doing some research, going through materials, doing research on what others have done for calibration. Mark suggested that we form an ad-hoc sub-committee, led by Sasha, to look at the problem.

Technical Design Report

Paul has started bringing the TOF section of the technical design report up-to-date. He remarked on the good structure of the document materials.

Mechanical Design

Chuck let us through the latest drawings for the support of the TOF modules. He drew up the concept for the center-section prototype. There has been significant progress since the last time the design was presented. Some of the discussion:

  • Kurt suggested independent support of soft steel shielding (curved metal pieces). Tim and Chuck will incorporate that.
  • Cross bars on the end, connecting the the support structure at one end of the counters to the other.
  • Pieces for the center-section prototype will be machined at FSU.
  • Drawings incorporating suggested changes will be sent to the FSU team before the next meeting.

New Action Items

  1. Form a sub-committee to work on calibration and alignment. -> Mark
  2. Send revised drawing to Team FSU -> Chuck
