Racks
• Some racks have been re-located
• To optimize cable lengths
• Reduce Bus Bar lengths

General Layout of Racks in UX25
Racks for TRD & TOF are to be
Moved nearer to the Detectors
TPC power supplies on RB24 side
Remain in same place under
shielding

Conclusions
• TPC services are well understood
• Concerns
-Bus Bar Call for Tender must not be delayed
-Integration of other pipes and cables has still to
be detailed
