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

DD 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.

DD 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
D. Lincoln Run II MTG May 12, Y2K
DD 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
