Transcript of Extra Services to be added to YB0 for the Tracker during LS1 . Preliminary table.
Extra Services to be added to YB0 for the Tracker during LS1.Preliminary table.The last item may also need to be added to the services on the vac-tank (probably preferable rather than connecting it to an existing Ericson fiber)
Extra services to be installed during LS1 on YB0
Extra services for Tracker to be installed on YB0 during LS1 per sideName Function Type Quantity OD (mm) Comments
DryGasWPBH Warm dry gas flexible pipes for bulk-head region flexible pipe 18 14 to be routed on YB0 to reach each of the
18 (EB/HB) sectors.
SnifferPipes Sniff for humidity from the bulk-head region copper pipes 9 6 to be routed on YB0 to reach each every
2 sectors
Xentaur readout xentaur humidity sensors
electrical cable (coax BNC) 8 5 to be routed on YB0 to reach 4 at the
bottom half and 4 at the top half
Pixel Power
provide power to the innermost layer of the upgrade phase I pixel detector
electrical cable (MSC6X4) 4 12.5
to be routed along the present Tracker cable distribution plant (2 reaching PP1 6A/-5C, and 2 reaching PP1 15A/-14C)
DPGprovide power and signal for new differential pressure gauges
electrical cable 2 5 to be routed one for top and one for bottom
FOSProvide extra T and H sensors from the bullk-head region
optical fiber ? ?likely only from PP1 to the bulk-head. Use existing Ericson fibers from PP1 to USC
HB Fibers Provide spares for HB for the TTC system. optical fiber 18 2
To be routed on YB0 to reach each one RBX. This is in view of the fact that with the HB upgrade the presently installed spares will be all used
Main issue: find space on the radial surface of YB0 to access the vac-tank. Once on the vac-tank there is much more space to move around (although still complex).Proposal: use already existing EB/HB Rest cable trays which still have a reasonable amount of free space.

Extra Services total cross-section is ~45 cm2 per side (at this moment).
Example:Considering the extra dry air pipes on the +Z side.Need to distribute 18 extra dry air pipes. We could consider adding 4 pipes on EB/HB Rest radial cable tray on muon sectors 5 and 9 and 5 pipes on muon sectors 1 and 8.

Need to feed 4 PP1s, for example: 14,15,16,17.I. Follow EB/HB Rest cables, cross over EB-LV cables (a) and mount on
the OF cable trays (b) and from there feed the chosen PP1s.II. Alternatevely, once on the vac-tank, they could follow EB-LV cables

Example:Muon Sector 9
SECTOR +9
Space available on the side of the ECAL rest cable tray is about 85mm in height by 70mm in width.Red protruding objects are DT gas feeder connectors.
Additional cooling pipes for Pixel Phase I upgrade: preliminary look
Most important:• Find space on the radial section• Minimize the routing complexity on the vac-tank
