D. Lincoln Run II MTG May 12, Y2K What will it take to get data out of the CFT? Work Lots and Lots of Work
3
D. Lincoln Run II MTG May 12, Y2K Central Fiber Tracker Status 8 layers u Outer 6 s 2.52 m u Inner 2 s 1.66 m r -.2 to.51 m Axial readout to south VLPC Readout Waveguide system u 8-11.5 m u “Pipes” light from detector to VLPCs
4
D. Lincoln Run II MTG May 12, Y2K CFT Status - Done Stuff Fiber Ribbons (roughly 400 ribbons) VLPC Characterization 17,000 chips tested, 15,500 OK VLPC Recovery 2,200 tested, 1,100 recovered u So total useful chips 16,600
5
D. Lincoln Run II MTG May 12, Y2K CFT Status - Ribbon Mounting 30 m rms 50 m e-e offset Going Very Well - To Spec Last cylinder (1) getting stereo ribbons attached now Project Tomorrow completion
6
D. Lincoln Run II MTG May 12, Y2K CFT Status - Nesting Cylinders 8,7,6,5,4 & 3 nested CFT Completion - 5/19/00 Delivered to DAB by 6/15/00 Global precision 15 m (Measured vs Desired)
7
D. Lincoln Run II MTG May 12, Y2K CFT Status - Waveguides Waveguide Production u CPS complete (IU) u Fiber pulling/sheathing at ND 75% complete for CFT s Fiber sorted –Best (attn.L from Kuraray) - longest runs [8-11.5m] u FPS at IU u CFT WG Connectorization s At ND + Fermilab + IU s 50 with curved end connectors Expect to complete production in August (100+ July 15) CFT Hookup and commissioning complete by 9/1/00
8
D. Lincoln Run II MTG May 12, Y2K CFT Status - Readout System VLPC Characterization/test /sort now complete Cassette Assignment u As shown (includes cassettes 1-10)
9
D. Lincoln Run II MTG May 12, Y2K CFT Status - Readout System II Cassette production u Approximately 50% of sub-component complete All components in-house except Flex circuit Flex Circuit u Production deliveries starting s 600 of 2000 in hand 100/week
10
D. Lincoln Run II MTG May 12, Y2K CFT Status - Readout III Cassette Test - Going Well u Noise low (Stereo Board) u Good uniformity
11
D. Lincoln Run II MTG May 12, Y2K CFT Status - Cryo Fabrication delayed by delivery of top plates u Now in house u To spec Making up some time u Welding going well Final Cryo Operational in June
12
D. Lincoln Run II MTG May 12, Y2K CFT Status - Conclusions CFT construction is going well u Mechanical assembly is to specification u Complete in mid-May VLPC + Cryo u VLPC characterization/selection complete u 1024 channel cassettes working well u Cassette production assembly underway s Subcomponents 50% complete s First 10 (11?) production cassettes assembled s All cassettes leaving factory have met specifications CFT wave guide production u Fiber pulling/sheathing going well (far along) u Connectorization underway

D. Lincoln Run II MTG May 12, Y2K Major Installation Activities During Next 3 Months April May June July Install/align CFT Platform moves: pick up EF north/south Install VLPC cryostats in platform Collision Wall down – Hi Bay full Rework EF shielding pieces End detectors installed (FPS, ICD, L0) Install N/S A-layer MDTs Install both EF shields Install gas/cooling lines in Collision Hall Rework/reassemble shielding mid-pieces Collision Wall back up Install CFT cable ductwork in platform Collision Wall down Stage/survey N/S shielding Solenoid Test Install N/S A-layer pixels Install EMC-S MDTs and pixels Crane needed Platform occupied ICR occupied CF closed; no cal preamp access survey Survey east PDTs survey Install South truss in Hi Bay, re-weld arms Forward Muon Installation Disassemble EMC-S for move to sidewalk to July 15

D. Lincoln Run II MTG May 12, Y2K DO Timeline Version N 2000 2001 J F M A M J J A S O N D J F M D Install silicon front-end CFT install/hookup 1/2 VLPCs installed 1st CFT crate operational Waveguide production All VLPCs installed Cosmic Ray Commissioning Phase I: Central muon, DAQ, RECO, trigger, silicon front-end Phase II: Tracker Commissioning (CFT, SMT, PS), VLPCs, Forward Muon Phase III: Full Cosmic Ray Run (add CAL, full TRIG & SMT) Run II begins: Mar 1, 2001 Roll in detector Remove shield wall Beam- ready Install final CFT electronics Platform moves No Services Install/hookup/checkout SMT South halfNorth half ICD FPS Lum (L0)
15
D. Lincoln Run II MTG May 12, Y2K Commissioning Plan CFT arrives DAB mid-June, install and survey (Gaston) Cryostat install and hookup through mid June, testing cooldown followed by cassette insertion, end of June (Russ) As waveguides hooked up (CPS, 8, 7, etc.), testing is needed Current plan: u 2 people/crew, 2 crews/shift, 2 shifts/day, 2 LG/crew/shift u 8 lightguides/day. (300 CFT light guides 8 weeks) Initial test, LED pulsers on the ribbons, secondary electrical. u Verify light continuity. u Verify photoelectron noise consistent with temperature and voltage u Electrical noise.

D. Lincoln Run II MTG May 12, Y2K Needed Components CFT cylinders: In DAB mid-late June Cryostat: Operational late-June Cassettes: In DAB June/July (30-ish, 11 in hand now) LHe: Tested already, hiatus early July (end iron) Lightguides: In DAB June/July, all CPS, 100 CFT (7/8 S/A) Cables: In house (AFE sequencer VRB) DAQ: Running now Unpacking: SVX unpacking done, some mapping remains. Examines: Available now, will need tweaking for commissioning Cosmics: Piggyback on muon trigger Tracking: Cosmic tracking mostly OK, minor technical fixes Event Display: Ready in some form
17
D. Lincoln Run II MTG May 12, Y2K Front End Electronics: u AFE not available, use stereo board, limited availability LED Electronics: u Two components, small card (300-ish), large driver/control card (10-ish) u Small cards available early June u Large controller cards maybe available mid-August...Gack! Sequencer VRB cable pull late July u Silicon uses same cables, need splitter, not available u Can pull the small number of CFT fiber optic cables first CFT Online guru: CFT Calibration guru: Not yet filled Control/Download guru: Needed Components }

D. Lincoln Run II MTG May 12, Y2K Summary Much of the required components are in place for mid-July hookup/commissioning Some aren’t They will be
