  • JLab: Chuck Hutton, Mark Ito (chair), Beni Zihlmann

Construction News

  • FIU has placed orders for bent scintillator and machining them with Eljen and McNeal respectively. The orders are for 50 pieces total. The work at McNeal will be done in batches of 25, with a period for quality checks at FIU between machining on the two batches.
  • There has been a delay in the construction of the test stand due to failure of the CNC machine at FIU. The machine should be fixed by next week[?].

Simulation Studies

Eric has started picking up the simulation projects that Puneet was working on, various studies of light collection efficiency.

Construction Drawings

Chuck circulated drawings of the inner foam support and the carbon fiber sleeve that adds support inside it.

Installation Schedule

The current schedule calls for the start counter to be ready for the April 2014 beam test. This looks tight, but possible. FIU will revisit the construction schedule.

Readiness Review

Bruce Lenzer asked about the date of the readiness review yesterday. Mark told him that things have been delayed and we are not ready to schedule the review yet.
