## What will it take to get data out of the CFT?

**Work**
**Lots and Lots of Work**

## Central Fiber Tracker Status

**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**

## 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**

## 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
