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
  • n one side of the Tracker disk.

Summary:

20

  • 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
  • ptimization.
