[email protected] IBL CO2 cooling routing proposal
• A survey of the routing possibilities in Atlas has been carried out to come up with a more detailed proposal than the one on the previous slide.
• Routing in difficult areas was simulated with 50mm PVC piping. A Mock-up is made which can be measured and modeled into CAD.
• The dimensions of the neighboring hardware were measured to find space for additional hardware and accessibility. Measurements will be used to check the available 3D models.
• Preliminary check of measurements is done with existing 2d drawings from CDD.
• A principle design of the full tube routing is made– Where to put manifolds, valves, etc. – What isolation can be applied (Foam / Vacuum).

[email protected] IBL cooling tube routing at inner detector.
• From the ID-end plate a nice path following the dry-air chimney was found to the top of the tile calorimeter.
• In the empty space between inner muon chamber of sector 5 and the tile calorimeter a path was found to accessible area between sector 5, BIL and BML layers. In this space the transition from IBL feed and return tubing to the concentric transfer tube can be made.
• Delicate equipment can be placed in this area as it is easily accessible.– Valves, filters, sensors.– Manifolds?
• Tubes to ID-end plate can be vacuum insulated and can be installed prefabricated.
• Insulation of transition hardware can only be foam insulated. Placement of a condensation catch channel underneath is possible.

[email protected] IBL transfer tube inside Atlas detector
• A straight path from the sector 5 cooling junction to the outside was found following the cryogenic LAR piping towards the cryogenic LAR plant at level 6.
• The straight path allow us to make the concentric transfer tube in the detector to be vacuum insulated.
• Concentric vacuum assembly can be made using 6m tubes. At the LAR cryogenic plant sufficient space is available for inserting 6m long tubes.
• Construction of 6m long tubes (standard trading length) gives weld joint locations in accessible areas. – BIL/BML sector 5 (Junction box)– BML/BOL sector 7 (Area behind small toroid access door) – LAR cryogenic plant at level 6.
• Routing and inserting was simulated using 50mm PVC piping.

[email protected] Transfer tube routing to cooling plant
• A nearly horizontal path was found to the cooling plant area in USA15
• Tubes follow LAR vacuum tube towards cavern wall and go along wall to the tube and cable tunnel.
• Tubes can be installed on top of C3F8 cooling channels to USA15
• Vacuum pump can be installed on cavern wall next to LAR vacuum pump
• Insulation will be foam from LAR cryogenic plant towards CO2 cooling plant

• A nice free space was found on an empty platform at the upper layer of USA15.
• Tube routing towards this space is easy.• Is this space available for the CO2 plant?

[email protected] Summary and conclusions
• Proposed tube routing from IBL to cooling plant is feasible and looks relatively easy to apply.
• Vacuum insulation in the detector – Except at junction area, but very accessible for a proper insulation.
Condensation catch channels will be installed as guarantee.• Pre-fabricated vacuum channel from junction to ID-end plate.• Vacuum insulated transfer line possible to manufacture in place.• Junction area is easy to access, this will be the location for most of
the sensitive hardware.• It will be investigated to locate the manifolds as well in the junction
area.– Long capillary tubing!!– Accessible manifolds.– Possibility to disconnect an IBL cooling channel.
• Can CO2 plant be placed at the free platform in USA15?21
