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
• 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.

calorimeter

zisis link to meeting page, minutes posted there tim will send something to the machine shop today

detector updates

beamline and tagger

design contract for tagger to procurement soon will be reviewed by acc division documents on the wiki are near up-to-date sampling of tagger interface drawing will be sent this week, tim

solenoid

coil 3 looks worse that we thought. completely open and replace some tubing, george. contract things to be sorted out started testing coils at jlab

target

tim meeting yesterday, reviewed tracking list, temporary solid target discussed for startup specification work to do reviewed racks for gas system, system itself alignment accuracies thermometry cryogenics: independent system or use magnet system

start counter

werner discussion started: geometry overall dimensions, stay-in zone target independent of start counter desired 2004 geometry for counters itself still looks good with current rate estimates

CDC

Yves reviewed status report on web Gerard had some concerns about cabling and grounding. will talk with Yves Gerard's trip to CMU has yet to be scheduled. He wants to look at some of the CMU hardware in advance of the trip.

FDC

Dan procurement wire winding work, waiting on final budget from IUCF composite wire frames, brian will have five by next week construction more accurate with new jig test lab set-up being put back together denny i is helping another offer of new space for fdc's downstairs in CC brian has space in eel. space in clean room being discussed with Jack Segal interposer/daughter boards has not yet been transferred from Fernando, not quite ready to test them yet FDC meeting tomorrow, agenda has been circulated combined FDC/CDC tracking meeting TBA

bcal

zisis cosmics with sipm on bcal monte carlo work continuing george working on statement of work for sipm's question for elke, test fibers have been ordered for S, kurai this week might be two months to get them without some special effort or arrangement

tof

beni nothing to report

fcal

beni test stand set-up for plastic wall for holding pmt's, test heat tolerance 8:30 fri. cd3 preparation meeting will get nim electronics from IUCF transportainer george asked about beamlines at triumf for testing

beamline available
need two month notice
8x8 block fcal test
electronics must come with experimenters

russion radhard lead glass blocks

1 block for 260$ limited accuracy in dimensions 2mm tolerance

calibration

christina collecting components for a prototype system discussion with company for purchasing LED drivers have some tiny LED's to start with

electronics

pre-amp cards, cables connectectors done this week, for FDC and CDC assembled and remain to be tested FADC 250 MHz is in good shape, FCAL and BCAL to provide trigger

online

Elliott not here

offline

DAvid l nothgint to report

Monte Carlo

Richard new geometry space between stereo and axial apckages endplate material dominiated by endplug, needs to be modeled propersly questions about bcal details
