Description
To cope with the High Luminosty LHC (HL-LHC) data taking contidions the tracker detector of the CMS will be replaced by a completely new and enhanced version within the Phase-II Upgrade. The future outer tracker consists of two barrel parts and two end caps where one end cap is made of five double-disks, each hosting the p_T modules on all four surfaces. The building block of the mechanical structure of the end caps will be half-disks (Dees). The contribution will cover the design of the services starting from the Dee level going up to TEDD level including the routing of the electrical, optical and cooling services, as well as module integration strategy and testing.
The contribution will provide details on the routing aspect of the services; how the different transverse services are routed out the Dee to their corresponding patch panels, grouped on Double Disk (DD) level, and forwarded to service channels longitudinally; their analysis and validation studies to finalize the design; the full optical & electrical chain, the material choice, and the challenges encountered will be presented. Once all modules have been integrated on a given Dee and integrated with their services, the Dee will be subjected to a series of tests in quality assurance purposes, making sure modules perform as expected, requiring active cooling of the Dees. The contribution will present the details of the testing procedure and environment with the first prototype realized and tested in Louvain.
