  1. TPC Signal cable plan Jin Huang (BNL)

  2. TPC DAQ nomenclature Input data stream: 600-1100 bidirectional fibers links Max continuous: 6.5 Gbps / fiber Output data stream to buffer box: 24 x 25+ Gbps Ethernet via fiberAfter triggering and compression • Clock/Trigger input: • Optical links • Clock = 9.4 MHz TPC DAM L3 Scope, 1.2.6 • 150k chan • 600 FEEs • 24 sectors • Continuousreadout Transfer to SDCC continuously Structure/ GEM L3 ScopesWBS 1.2.1-4 FEE L3 Scope1.2.5 DAQ L2 ScopeWBS 1.6 Buffer box Jin Huang <jhuang@bnl.gov>

  3. Cabling plan 24 sectors total, 12 Sector each side. For each sector: 1x FELIX-EBDC, 2x 48F MTP trunk cables from DAQ room to TPC MTP<->LC break up in TPC endcap. 40 bi-directional LC <-> 26 FEEs MTP cable x(48+12): Outer diameter = 6-9 mm; Weight = 22-79 kg/km; Max install tension = 600-800 N; Minimal bend radius = 9-27 cm; Operating temperature: 0-70C.
