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!

Stephen Hillier, University of Birmingham Major areas covered Numbering and allocation to receiver crate/module for: TBB output cables TDB output cables Tile-Cal summer output cables Specification of receiver interconnect daughterboards Cable numbering/pinout of receiver output/PPM input cables Connectivity for various types of patch panel Tile input merging/splitting off muon signals Summing interconnects (internal to receiver system) Repackaging of some receiver outputs for PPM PPM crate/module layout PPM LVDS output cable numbering and module allocation CPM and JEM LVDS input cable module allocation Wednesday, July 2, 2003 Stephen Hillier, University of Birmingham

Stephen Hillier, University of Birmingham 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 Wednesday, July 2, 2003 Stephen Hillier, University of Birmingham

Overview of connectivity About 1500 analogue cables About 2000 LVDS cables 340 modules … in 22 crates 9 types of patch panel Wednesday, July 2, 2003 Stephen Hillier, University of Birmingham
