1. ATLAS Internal ID Service Integration
An update on service layout proposals by the UK
John Hill

2. Recent Developments Detailed schemes and layouts produced at RAL
Prototype manufacture of components. Duct, covers and connector block
Dummy assembly of ‘Service Module’ progressing. Dummy cooling pipes added to assembly
Schemes and progress presented to CERN Integration Group. Much interest shown in the design, positive feedback with some comments mainly on manifold layout and electrical connectors
Successful interaction of ID information with CERN and Valencia.
Some areas require further development and study. Gas sealing, thermal transition of cooling, grounding and component location

5. With the Service module partially constructed and using the full size mock up at RAL we can now adopt this structure to investigate Inner Detector fitting and further optimise cooling pipe layouts to staves

7. Alternative connector solutions have also been modelled and can be investigated further on ID Mock Up
Layouts using alternative ‘Fischer’ connectors, separating DCS and Power services (these are hermetically sealed units)
Hermetic seal made here
Layouts using CERN Axon connector (mounted on PCB) and fitted onto connector panel

8. Modelling area of Thermal Transition (SM to PP)
It is planned to make dummy components for SM prototype at RAL using ‘Insulating’ material backed with c-f sheet

10. Future work plans
Development work to continue on the SM prototype and integration on to ID mock up at RAL
Complete cooling layout to progress with welding trials on ID mock up
Potential to weld up a section of cooling with manifold to undertake pressure tests
Look at alternatives to manifold layout within SM
Maintain Service Module documentation for future reviews
Failure and risk analysis, list and document for service module design
Continue to develop service and design links, exchange ideas with CERN and Valencia
