Support Structure for the Inner Tracker Disks Requirements & Objectives • Due to the fact that the Inner Sub ‐ System includes the beam pipe, the supports for all components, including the Inner Tracker Disks should be designed with two halves Design proposal needs to be implemented in such a way to take into account some • aspects coming from the assembly procedure • Support structure should be easily attachable to the Support Tube and be compatible with the gaps which were established for the services • Due to the detector performance, we are looking for a stiff and lightweight construction One of the major objectives is to minimize the value of radiation length and make the • structure as much invisible for the particles as possible. For the time being, We assumed the scenario when the petals would be mounted only • on one side of the Tracker disk. 3/23/2016 Szymon Krzysztof Sroka, Wolfgang Klempt 5

Summary:  Design concepts of the mechanical supports for the Inner & Outer Tracker disks have been shown.  Promising feedback related to the material budget & mechanical response of the structure.  The concepts are still ongoing towards further optimization. 3/23/2016 Szymon Krzysztof Sroka, Wolfgang Klempt 20
