D0 PMG 6/15/00 PMG Agenda June 15, 2000 Overview (Tuts) u Detector status u Reportable milestones u Financial status u Summary Response to DOE review (Womersley)
2
D0 PMG 6/15/00 Status Overview Silicon u Just reported at DOE review
3
D0 PMG 6/15/00 Status Overview Forward Preshower u Both detectors installed ICD u North & South Installed Luminosity monitor u North & South Installed Fiber tracker u Just reported at DOE review u Some update u Preparing the move to DAB
4
D0 PMG 6/15/00 Fiber Tracker Status Waveguide QC going well u Final acceptance criteria are still being developed s Likely to accept two bad channels per wavguide (256) Falling off production schedule u Priming “pipelines”.
5
D0 PMG 6/15/00 Fiber Tracker Status VLPC Cassettes u Sub-component assembly s 65-80% complete u Final production cassette test/characterization not quite started
6
D0 PMG 6/15/00 Status Overview Central Muons u Commissioning continues Forward Muon detectors u Trig Pixels s All octants assembled & tested & starting to move to DAB s HV commissioning complete s VME crate installation started s A layer supports in production u MDTs s A layer octants installed s B octants all parts on hand s C octants: 15 done s C layer supports in production
7
D0 PMG 6/15/00 Status Overview Trigger & DAQ u progressing – far from critical path Online u No schedule concerns, not on critical path u Good progress on internal commissioning milestones ( pushing on subsystems) u Supporting silicon 10% test Solenoid and beam pipe u No changes since last time
8
D0 PMG 6/15/00 Status Overview; Electronics Electronics u Calorimeter s Preamps 99% complete s BLS delayed – solving coherent noise problem u Muon s PDT electronics - done s Scintillator –Front end Found missing part, done by end of month –Readout card - done s MDT - done s Readout electronics –Readout 100% –Fanout 15%; released for production
9
D0 PMG 6/15/00 Status Overview ; Electronics u Tracking Electronics s Released Si interface card production bid process –Still have final changes to make s Concerned about low mass cable cross talk –Being studied –Understanding how to speed up production – possible $ exposure s Analog Front End boards –Release order for 10 pcs (4 wks) s MCM yields lower than anticipated –Based on small sample –May have $ risk (contracted for 15% loss)
10
D0 PMG 6/15/00 Installation Installation u Shielding articulated on North Truss u Surveyed A layer chambers u A Pixel sheets being assembled on wall u VLPC cryostat have leaks (near lids) s 2 week delay (remachine) s Anticipate getting in before platform moves u Started cabling s Interface card – sequencer – ok
11
D0 PMG 6/15/00 Summary Concerns u Silicon continues……. u Waveguides are concern u Use of contingency: we are using it s Both kinds: schedule and funding
