Support Structure Investigations for the LHCb Mighty Tracker in Upgrade II — •Ksenia Solovieva, Todor Todorov, and Marco Gersabeck — Albert-Ludwigs-University,Freiburg

In preparation for the challenging environment of the High Luminosity LHC, the LHCb detector will undergo major improvements. The Upgrade II is scheduled to be installed during Long Shutdown 4 and includes a replacement of the downstream tracker. The current scintillating fibre tracker detector will be replaced with a hybrid system, the Mighty Tracker, comprising layers of improved scintillating fibres and 6 layers of silicon pixel detectors. The latter requires optimisation in the detector design, service routing and support structures to adhere to a strict material budget of below 1% X/X0 per layer. In this presentation, early considerations and studies of potential support structure solutions are discussed.
