1 D. Lincoln Run II MTG May 12, Y2K What will it take to get data out of the CFT?* Don Lincoln CFT Commissioning Czar Fermilab Run II Meeting May 12, Y2K * that’s John’s title, not mine........

2 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

13 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

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.

16 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  }

18 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
