The large gaps between the muon chambers of S1, S3 & S7 give a very open path to the S5 platform proposed for the manifold. If use sectors 3&5 will have a symmetric system

Gaps on IDEP – How many flex lines do we need to fit?
Based on the layout presented by the detector groups a 5kW flex line is chosen as baseline for PP2 to PP1 distribution
The total number of flex lines foreseen is 38 (Pixel)+36 (Strips)=74 lines (37 per side)
The vacuum shielded diameter is estimated to be 50mm
