PMG AgendaFeb 3, 2000
  • Overview
    • Project Manager’s Report – Tuts
    • Fallback options – Weerts
  • Silicon Support Cylinder Modifications - Cooper
  • Fallback Options & Installation - Kotcher
completed reportable milestones
Completed Reportable Milestones
  • 3 early
  • 3 on schedule (|.2w|)
  • 7 late
status overview since last pmg
Status Overview since last PMG
  • Silicon sensors
    • Axial (3 chip)
      • No problems
    • 90deg (6 chip)
      • Micron delivery an issue (sputterer problem at Micron, being fixed)
      • Micron delivery paces
      • Fallback – accept lower grade detectors
    • 2deg (9chip)
      • Production going well (last batch 19/25 passed)
      • Full delivery in April
    • F wedges
      • Proceeding well at 50-60% yield at Micron (last batch 5/6 passed)
      • Received 5/75 sensors from Eurisys
    • H wedges
      • 60 more on order
silicon
Silicon
  • HDI
    • Getting sufficient HDI’s to keep pace with production is a problem
      • Expediting additional HDI orders
      • 2nd vendor for bonding, Silitronics, looking good
    • H wedge
      • 2 HDI left, as expected
      • Production stops for 4 wks
    • 2deg (9chip)
      • Out of HDI’s, rounding up what is available 5-9
    • F wedge
      • Almost out of HDI’s
silicon6
Silicon
  • Ladder & Wedge production
    • Axial (3 chip)
      • Picking up next week
    • 2deg (9chip)
      • Production lagging, out of HDI’s
    • 90deg (6chip)
      • Paced by Micron delivery
    • F wedges
      • Limited by HDI availability
    • H wedges
      • Limited by HDI availability
fiber status
Fiber Status
  • Fibers
    • Waveguide production going well
      • 175 bundles pulled & cut
    • Cylinders 8, 7 complete
    • Nesting cart is being measured; delays by about 4 weeks
      • 8a and 7a installed and glued
      • Final stiffness tests in progress
      • Start assembly next week, 2/7
    • Flex circuits still a concern, delaying complete start of VLPC cassette production
      • Compunetics 100pc order nearly complete – 34 good, 31 to go
      • 1st production cassette under test
      • Many components done while awaiting flex circuits (~20%)
fiber tracker status
Fiber Tracker Status
  • Ribbon Production
    • Continues
fiber tracker status10
Fiber Tracker Status
  • Ribbon Mounting
    • Continues
      • C8 and C7 Done
      • C6 axial started
status overview
Status Overview
  • Preshowers
    • Some schedule re-arrangement, net speedup
  • Tracking Electronics
    • Some (2-4wks) slippage in layout and vendor production, worry here…….
  • Calorimeter Electronics
    • 98% of preamps (59kch) in hand
    • Power supplies complete
    • 80% of packaged SCA’s in hand, will need to order 5k more
    • Small layout problems cause 6 week delay to BLS schedule
    • Installed 2 power supplies & 16 card of preamps in detector with online controls for p.s.
status overview12
Status Overview
  • ICD
    • Module testing underway
    • Preamps in hand, motherboard ordered
  • Central Muons
    • Commissioning continues
    • First ½ truss in D0 Hall
  • Forward Muons
    • Trig Pixels: Proceeding well on schedule.
    • See no problems meeting April completion date
    • MDTs: @Dubna completed. Being shipped in heated container.
    • Production on A MDTs layer has started
    • C MDT parts presently most critical items (panels, etc)
trigger pixels
Trigger pixels

The forward muon trigger planes:

3 planes: A, B, C with 16 octants ( north & south) each

All pixel counters are at FNAL

Layers A & C are completed

Layer B started

mdt chambers octant assembly
MDT chambers & octant assembly

The tracking planes:

MDT production at Dubna complete ( shipping)

A layer assembly done

status overview16
Status Overview
  • Trigger & DAQ
    • Proceeding well
    • Delays in some in 12MCM boards ( stereo CFT, CPS, FPS), because of engineering
  • Online
    • Manpower in good shape
    • No schedule concerns, not on critical path
    • Being tapped for manpower in other systems
summary
Summary
  • Concerns
    • HDI deliveries
    • Silicon testing
    • Fiber flex circuits for VLPCs
    • Forward muon installation
    • M&S cost contingency continues to dwindle
  • On the horizon
    • Lehman review…….
