1. Front-End Cabling ‘Bible’
Culmination of much detailed work by Murrough and Steve, in response to ASSO 2001
Expected date April 2002! (Sorry)
Based heavily of work of Bill Cleland
Cabling of the ATLAS LAr Receiver System etc
and Paul Hanke
PPM specification (Appendix A)
60 Pages: about 20 of text, 40 of figures
cf Norman’s ‘most boring document’
We have a contender!

Status
Document is essentially complete
However:
Tile Calorimeter patch panels very provisional
Requires some reviewing (internal and external)
Only part of the layout working group’s task
Needs to be put into EDMS
