Prototype Commissioning

At Lab 3, a prototype cosmic ray test has been underway for about a year.

To date: Tested two cylinders (3A & 3B) Lightguides and connectors Prototype cassettes (final design) Cryogenics and control Prototype analog electronics boards

(‘stereo’ boards, with SVX-II readout) Standalone sequencer DAQ

Soon Final sequencers VRB readout

Eventually Final analog board (AFE) shakedown

Pre-installation Commisisoning

At Lab 3, all components of the CFT will be tested.

Fiber positions are surveyed. During nesting, each cylinder

is aligned to the others on CMM.

CFT arrives at DAB as a single-piece unit.

Each VLPC cassette is qualified at Lab 3

Each lightguide is tested at ND or IU prior to shipping.

Note about the legend:

“All” - refers to effort assigned to all tasks in the relevant schedule

“Install.” - refers to effort assigned to a subset of those tasks flagged as installation tasks

Tech effort is sum of MTF112+ETF112

DD


Summary

All components will be pre-tested and pre-commissioned, prior to arrival at DAB

Lightguide map is complete.

Manpower lists here are adequate for installation

Will need close cooperation with electronics group for cosmic ray commissioning
