D0 PMG February 15, 2001 Fiber Tracker Status Waveguide Production and QC continue at a very small scale; use less fiber ( $100K $50K) Installation Waveguides u South & North: done VLPC cassettes Goal (99): projection was Feb 26, 2001 now mid March, due to AFE testing 91 fabricated, 87 characterized, 66 @D0, 12 more ready for DØ

D0 PMG February 15, 2001 Status Overview Central Muons (94 PDT’s) u Commissioning continues u Triggering on tracks Forward Muon detectors u All commissioned, except B layer pixels; u C layer pixels to finish ( timing) Gas systems (recircl. & clean) u Being installed LayerPixelsMDT’s A North & South: done North & South: done B North & South: done North & South: done C North & South: done Installation status

D0 PMG February 15, 2001 Status Overview; Electronics Electronics u Calorimeter s Preamp installation/commissioning underway (55k installed: all done, EN & CC power ready, cooling installed, ES going in) s BLS status –Motherboard: 1250/1200/1020 – need/bare/stuffed – ( no progress: 50/week; should 100/week) –Daughter cards 5000/5000/4220 –Daughter card: 300/week should; but none in last few weeks ( ORACLE SUNYSB ??) –CC, ECN were cold and filled with liquid; now empty –Have 4 out of 12 timing modules ( boards being assembled) s Have read out 4500 channels u Muon s Done

D0 PMG February 15, 2001 u Tracking Electronics s Si Interface Card –144 needed –All boards in hand –144-4 tested and ready s Adapter card –Done fabricating –& installed south side s Analog Front End boards –Remake the PCB’s (148)( second set) –Release Feb 19 –PCB status clear: remake !!! –Have 10 prototype boards –4 stuffed; 2 being tested –Tests look promising, but have to continue –Latest release date for stuffing March 19 s MCM going –At FNAL 2220; need 2200 s Power supplies –Being installed Status Overview; Electronics SMT Fiber tracker

D0 PMG February 15, 2001 Description # need # ready Location Waveguides from CFT (axial & stereo), CPS, FPS - CFT & CPS DONE From face of CC to platform VLPC cassettes9987platform AFE 8 with 8 MCM’s; readout axials & stereo 136 incr. 10 proto problem On VLPC cassttes MCM; multichip module with SIFT & SVX chip 22002212 On AFE xx boards AFE 12 read out stereo, CPS, FPS 62 Progress design On VLPC cassettes Mixer boards (trig) 20 2 end of March; Prototyp es on way Digital part (trig) 40 24 & arriving platform Fiber tracker readout front end system status DAQ AFE 8 VLPC AFE 12 VLPC CFT, CPS, FPS L1 Trig Infrastructure installed

D0 PMG February 15, 2001 Status Overview Trigger u Final hardware arrival is a worry Level1: CFT trigger; digital parts arriving March CAL few towers on March 1 & run; delivery in March Muon ~2octants in central & 1 in each end; arriving in March & April L2 VME-Alpha boards still a concern. Looking better: 25 produced; 3 partially working; 6 completely working. Expect another 2 to rise from dead. Three approaches: Effort in CD continues (THANKS) Another production run. Have parts for 12 boards. New design completely….. L3 board production concern Abandoned high speed SIB design on PCI card with high bandwidth IN and OUT Goal now is to achieve 50 to ~150Hz in April Two critical boards (SIB, VBDi). SIB have boards, VBDi going out Online u In use at low rate, not on critical path
11
D0 PMG February 15, 2001Summary Concerns u Installation: Mechanically complete u Electronics delays are THE concern for realistic commissioning with beam s Vendor delays, parts availability Outlook u “Detector” will be ready for beam on March 1 u All detectors will be installed u Not completely hooked up u Limited data rate in DAQ ~few Hz u Will need TIME after start up to complete the detector electronically ( see later)
