Latency

Current Critical Path (Jet/Et)

Component	Cable to next

Receivers (EM Barrel/Hadronic Sum)	1m?$\rightarrow$
Receiver stations	10m$\rightarrow$
PreProcessor Modules	7.5m$\rightarrow$
Jet/Energy Modules	2.5m$\rightarrow$
Energy Sum Merger Modules	2.5m$\rightarrow$

Longest TTC Fibres	80m$\rightarrow$FE

Total latency in TDR was 82.2 BC. This is 2.2 BC, ie 11m cable over the target.

Less Critical Paths

• Muon Trigger (about 2 BC to spare, ie 10m of cable)
• Cluster Processor (about 4 BC to spare, ie 20m of cable)
