Current Proposal

• Calo Trigger on upper floor of USA15
• Muon Trigger (and CTP, TTC?) on lower floor
• Calo processor in 14 contiguous racks
• Outlying racks for other services (computers etc)
• Receiver crates at the outside, then preprocessor, trigger processors at the centre
• EM one side, hadronic the other side
• Receiver crates grouped by detector (social reasons)
• Muon RPC and TGC processors either side of a gap in the racks
• CTP and TTC racks near the centre (maybe upstairs if necessary?)
