Rack Layouts (2)

Proposed Layout

• Calorimeter Trigger upstairs
• Continuous row of centrally placed racks
• Receiver crates at the outer ends connecting to PreProcessor and the Cluster and Jet/Et processors in the middle
• Muon Trigger downstairs
• RPC and TGC triggers either side of central gap?
• CTP and TTC downstairs?

Outstanding Issues

• Confirm holes in shielding wall with TC group. We want the two 400mm holes to niveau 2 now
• Still need to confirm number, size and bending radius of cables and communicate to TC group
• Choice of cable from TileCal (to Calo and Muon triggers) still not made
• Receiver crate may require cable supports extending outside the 1m deep racks
• Location of TGC electronics still not decided?
• What is the critical latency path? Maybe via Silicon Tracker racks in USA15?
