What will it take to get data out of the CFT? • Work • Lots and Lots of Work

Central Fiber Tracker Status • 8 layers • Outer 6 • 2.52 m • Inner 2 • 1.66 m • r - .2 to .51 m • Axial readout to south • VLPC Readout • Waveguide system • 8-11.5 m • “Pipes” light from detector to VLPCs

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 • So total useful chips 16,600

CFT Status - Ribbon Mounting Going Very Well - To Spec 30 mm rms Last cylinder (1) getting stereo ribbons attached now Project Tomorrow completion 50 mm e-e offset

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 »15mm (Measured vs Desired)

CFT Status - Waveguides • Waveguide Production • CPS complete (IU) • Fiber pulling/sheathing at ND 75% complete for CFT • Fiber sorted • Best (attn.L from Kuraray) - longest runs [8-11.5m] • FPS at IU • CFT WG Connectorization • At ND + Fermilab + IU • 50 with curved end connectors • Expect to complete production in August (100+ July 15) • CFT Hookup and commissioning complete by 9/1/00

CFT Status - Readout System • VLPC Characterization/test/sort now complete • Cassette Assignment • As shown (includes cassettes 1-10)

CFT Status - Readout System II • Cassette production • Approximately 50% of sub-component complete • All components in-house except Flex circuit • Flex Circuit • Production deliveries starting • 600 of 2000 in hand • »100/week

CFT Status - Readout III • Cassette Test - Going Well • Noise low (Stereo Board) • Good uniformity

CFT Status - Cryo • Fabrication delayed by delivery of top plates • Now in house • To spec • Making up some time • Welding going well • Final Cryo Operational in June

CFT Status - Conclusions • CFT construction is going well • Mechanical assembly is to specification • Complete in mid-May • VLPC + Cryo • VLPC characterization/selection complete • 1024 channel cassettes working well • Cassette production assembly underway • Subcomponents 50% complete • First 10 (11?) production cassettes assembled • All cassettes leaving factory have met specifications • CFT wave guide production • Fiber pulling/sheathing going well (far along) • Connectorization underway

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: • 2 people/crew, 2 crews/shift, 2 shifts/day, 2 LG/crew/shift • 8 lightguides/day. (300 CFT light guides  8 weeks) • Initial test, LED pulsers on the ribbons, secondary electrical. • Verify light continuity. • Verify photoelectron noise consistent with temperature and voltage • Electrical noise.

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

Needed Components  • Front End Electronics: • AFE not available, use stereo board, limited availability • LED Electronics: • Two components, small card (300-ish), large driver/control card (10-ish) • Small cards available early June • Large controller cards maybe available mid-August...Gack! • Sequencer  VRB cable pull late July • Silicon uses same cables, need splitter, not available • Can pull the small number of CFT fiber optic cables first • CFT Online guru: • CFT Calibration guru: Not yet filled • Control/Download guru: }

Summary • Much of the required components are in place for mid-July hookup/commissioning • Some aren’t • They will be
