Cables from Detectors
- Cables from detector all brought to the centre
- Into USA15 via six holes: three 300mm upstairs,
two 400mm and one 300mm downstairs.
- Used by Calo trigger cables, Muon trigger cables (inc TileCal),
return TTC fibres, magnet cables, maybe others?
- Cables from endcaps include loops to allow endcaps to be retracted
- Restricted space near the detectors imposes a maximum bending
radius of 10cm. Present LAr cables have 15cm bending radius!
Cabling inside USA15
- Cables to receivers up from the floor
- Receivers to PPMs: across the front
- PPMs to CPMs/JEMs: under floor (or over the top?)
- Cabling to CPMs to the back; JEMs to the front
- Other cabling (from mergers; to RODs) is less bulky
- NB need to check CPM/JEM to ROD cable length
