• UConn: Richard
• IUCF: Gerard
• CMU: Curtis, Yves
• Athens: Christine

Announcements

Elke had a few:

• JLab in a hiring freeze at present
• Next week, Monday trought Friday, is the EVMS review
  • cost account managers will make presentations
  • physics is scheduled for Wednesday morning

Elke proposed that we drop our meeting for next week. All agreed.

R&D Contracts

Elke reported on this item.

• Work proceeds in conjuction with JLab Procurement
• Several contracts that ran from 2002 to 2007 have to be re-visited
• These include IUCF and Regina - The Regina one has been dealt with: second last invoice has been sent, last one will be after Phase-1 close out before the end of the year
• Most likely these contracts will be closed and re-open with new ones.
• Elke has list of all known contracts
  • It is an Excel spreadsheet
  • She will send it around soon.

Report from Calorimetry Technical Group

Zisis reported on items from the last meeting of the group. See his minutes for details.

Tim will send something[???} to the machine shop today.

Detector Updates

beamline and tagger

• Elke: design contract for tagger to go to procurement soon
  • will be reviewed by accelerator division
• Elke: documents on the wiki are near up-to-date
• Tim: sample for tagger interface drawing will be sent this week

solenoid

Elke reported items from George:

• coil 3 looks worse that we thought
  • will completely open and replace some tubing
  • there are some contract issues with IUCF to be sorted out (see above)
• we have started testing coils at JLab

target

Tim reported on yesterday's meeting.

• reviewed tracking list
• temporary solid target discussed (for sue during startup)
• specification to-do list reviewed
• discussion of racks for the gas system, gas system itself, were discussed
• discussion of alignment accuracies
• discussion of thermometry
• discussion cryogenics: independent system or use magnet system

start counter

Werner reported on discussions of geometry. Some items:

• overall dimensions, stay-in zone
• target independent of start counter desired
• 2004 geometry for counters themselves still looks good with current rate estimates

CDC

Yves gave a detailed report on recent progress at CMU. See his status reports (1, 2) on the web for details.

Gerard had some concerns about cabling and grounding based on the photograph of the prototype. He will talk with Yves offline.

Gerard's trip to CMU has yet to be scheduled. He wants to look at some of the CMU electronics in advance of the trip.

FDC

Dan gave the report:

• Procurement of the wire winding contract is waiting on final budget from IUCF
• Composite wire frames are being produced. Brian will have five by next week.
  • construction is more accurate with new jig
• Test Lab set-up being put back together. Denny Insley is helping.
• another offer of new space for FDC's downstairs in CEBAF Center has materialized
  • Brian also has space in the EEL.
  • Space in the clean room being discussed with Jack Segal
• Interposer/daughter boards have not yet been transferred from Fernando. FDC group not quite ready to test them yet.
• There will be an FDC meeting tomorrow; agenda has been circulated
• The combined FDC/CDC/tracking meeting TBA
