ATLAS Pixel DetectorPP1b integrated with Panels
• Panel design motivated to increase space internal to the ID Endplate
• Panel Layout divided to fit integration with Service Panels—corrugated panels integrated with corresponding service panel
• Panel lengths/widths sized to pack well into R450, and to fit through PST for installation
• Design required accurate connector count…

ATLAS Pixel DetectorConnectivity Tables
• Module to PP0– Developed table which maps each single module to unique connector on PP0– Followed naming conventions developed in Service Doc, invented new where
necessary– Includes calculation of Length of Type 0 cable
• PP0 to PP1b (through PP1 Penetration Flex)– Table maps each PP0 Flex (Half-Stave/Sector) to a unique set of function-
specific connectors at PP1b– Includes routing through PP1 flex– Logically splits at PP1 flex to map to Type2 cables defined in Service
document– Invented PP1b Corrugated Panels—includes mapping to positions on panels
• Tables Split into Inner and Outer Service Panels (Side A&C for PP1b)– Decided to move ‘third hit’ to Inner Service Panel to allow for easier staging
of detector Services– Disks 1&3 and Layers 0(B-layer) & 2 are on the Outer Service Panel– Disk 2 and Layer 1 are on the inner Service Panel
• Propose to Freeze this routing pending– Verify independently/include some auxiliary information

ATLAS Pixel DetectorData Sources Used to Develop Tables
• Module Positions– Drawings, Layout Document
• Service Document – Naming Schemes– Numerology– Cable Definitions
• Models of Service Panels– Invented Naming convention for Service Panel Components—following Service Document– Positions of PP0 Connectors– Panel Corrugations
• PP1 Penetration Flex– Invented Naming Convention– Followed ‘Design Rules’ based on Maurice’s Concept
• LEMO Connectors– Baselined Mauro’s choice of LEMO Connector– Solid Models from LEMO
• PP1 Corrugated Panels– Invented Corrugated Panels to hold Lemo connectors– Populated Panels with connectors with correct ‘count’ of connectors

ATLAS Pixel DetectorNumerology and Naming Convention
Overview
• Naming convention of elements tied to geometry– Where possible, this is tied to the ‘Absolute’ ATLAS scheme
(clockwise on side C– Where articles are identical, or mirror symmetric, this is
sometimes broken– All names are unique when concatenated
• Some Conventions are new—invented to cover items designed since the writing of the service document– These items follow the above rules– Some items (of higher importance) I have left un-named, but left
space in tables to discuss naming conventions here• Includes unique ID of Cables/Connectors• May want to include ProdDB reference• May want to use Connectivity Tables to formulate Relational
Connectivity Database

ATLAS Pixel DetectorPP1b Outer Service Panel Locator
• Connectors identified by indicial position [Row;Position]– Row Numbered from low to hi Z– Position numbered from Flex toward center of SQP
• Numbers on connectors are PP1 Flex designations– Most flexes share connectors, most are designated L/R which is defined in the ‘assembly’
coordinates…
• Note—OSP has 21 connectors, One must be supported by the PP1b-ISP neighboring

ATLAS Pixel DetectorPP1b Inner Service Panel Locator
• Connector From OSP is always the same—NTC/OPTO from flex #7• In event of 2-hit system—this connector must be supported
another way• Also—Inner Panel Penetration Flex is still required but limited to
Environmental/Cooling Sensor Wires

ATLAS Pixel DetectorType0 Cable Lengths
• Routing Information Buried in Spreadsheet
• Used Various Drawings to extract geometry information—need to check that all is most current
• Length check by Andreas gets within few mm, but need to make consistent
• After this check, freeze Cable Lengths

ATLAS Pixel DetectorConclusions
• Work near complete, would like to freeze without further optimization—only verification
• Work to be verified– Lengths of Cables– Cross-check against all cable types– Naming verification (convention)—should do prior to release for approval
• Work to be done—still quite a lot– Tube connectivity– Opto connectivity
• Increase Granularity of Mapping– Pin-outs for connectors—can be done independently – Map tube-connectivity/naming and respective temp sensors to pin-out level– Include ‘Environmental’ sensors in detail
• Design/Prototyping– Build ¼ PP1b segment using real connectors, and production methods– Thermal environment modelling—understand internal gas temp, opto-cooling,
cable-cooling—need to understand what to do with auxilliary cooling circuits…
