D0 PMG 2/3/00 Status Overview since last PMG  Silicon sensors u Axial (3 chip) s No problems u 90deg (6 chip) s Micron delivery an issue (sputterer problem at Micron, being fixed) s Micron delivery paces s Fallback – accept lower grade detectors u 2deg (9chip) s Production going well (last batch 19/25 passed) s Full delivery in April u F wedges s Proceeding well at 50-60% yield at Micron (last batch 5/6 passed) s Received 5/75 sensors from Eurisys u H wedges s 60 more on order

D0 PMG 2/3/00 Silicon  HDI u Getting sufficient HDI’s to keep pace with production is a problem s Expediting additional HDI orders s 2 nd vendor for bonding, Silitronics, looking good u H wedge s 2 HDI left, as expected s Production stops for 4 wks u 2deg (9chip) s Out of HDI’s, rounding up what is available 5-9 u F wedge s Almost out of HDI’s

D0 PMG 2/3/00 Silicon  Ladder & Wedge production u Axial (3 chip) s Picking up next week u 2deg (9chip) s Production lagging, out of HDI’s u 90deg (6chip) s Paced by Micron delivery u F wedges s Limited by HDI availability u H wedges s Limited by HDI availability

D0 PMG 2/3/00 Production Status

D0 PMG 2/3/00 Fiber Status  Fibers u Waveguide production going well s 175 bundles pulled & cut u Cylinders 8, 7 complete u Nesting cart is being measured; delays by about 4 weeks s 8a and 7a installed and glued s Final stiffness tests in progress s Start assembly next week, 2/7 u Flex circuits still a concern, delaying complete start of VLPC cassette production s Compunetics 100pc order nearly complete – 34 good, 31 to go s 1 st production cassette under test s Many components done while awaiting flex circuits (~20%)

D0 PMG 2/3/00 Fiber Tracker Status  Ribbon Production u Continues

D0 PMG 2/3/00 Fiber Tracker Status  Ribbon Mounting u Continues s C8 and C7 Done s C6 axial started

D0 PMG 2/3/00 Status Overview  Preshowers u Some schedule re-arrangement, net speedup  Tracking Electronics u Some (2-4wks) slippage in layout and vendor production, worry here…….  Calorimeter Electronics u 98% of preamps (59kch) in hand u Power supplies complete u 80% of packaged SCA’s in hand, will need to order 5k more u Small layout problems cause 6 week delay to BLS schedule u Installed 2 power supplies & 16 card of preamps in detector with online controls for p.s.

D0 PMG 2/3/00 Status Overview  ICD u Module testing underway u Preamps in hand, motherboard ordered  Central Muons u Commissioning continues u First ½ truss in D0 Hall  Forward Muons u Trig Pixels: Proceeding well on schedule. u See no problems meeting April completion date u completed. Being shipped in heated container. u Production on A MDTs layer has started u C MDT parts presently most critical items (panels, etc)

D0 PMG 2/3/00 EMC north truss, being taken apart for transport to D0. January 31, 2000

D0 PMG 2/3/00 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

D0 PMG 2/3/00 MDT chambers & octant assembly The tracking planes: MDT production at Dubna complete ( shipping) A layer assembly done

D0 PMG 2/3/00 Status Overview  Trigger & DAQ u Proceeding well u Delays in some in 12MCM boards ( stereo CFT, CPS, FPS), because of engineering  Online u Manpower in good shape u No schedule concerns, not on critical path u Being tapped for manpower in other systems

D0 PMG 2/3/00 Summary  Concerns u HDI deliveries u Silicon testing u Fiber flex circuits for VLPCs u Forward muon installation u M&S cost contingency continues to dwindle  On the horizon u Lehman review…….
