CFT Status - Readout System

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

9
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

10
CFT Status - Readout III

• Cassette Test - Going Well
• Noise low (Stereo Board)
• Good uniformity

11
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

12
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.

16
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
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 arent
• They will be
