Future of Silicon Tracking Detectors: LHC Upgrades and Beyond — •Georg Steinbrück — Institut für Experimentalphysik, Universität Hamburg

In this presentation I will review silicon detector technologies for particle tracking in current and future hadron collider experiments.

Significant improvements were needed to reach the requirements for the Phase 2 upgrades of the LHC experiments. I will report on these challenges and the technological solutions with a focus on the upgrades of the CMS and ATLAS tracking detectors. While the collaborations are moving towards production, they are already looking into the future. An overview of further upgrade ideas for the LHC tracking detectors will be given.

The demands on silicon detectors for planned future hadron colliders are even more extreme with 1 MeV neutron equivalent fluences up to 10^17 cm^-2 and huge particle rates. The limiting factors for the use of silicon will be discussed, as well as what is relevant in extrapolating current technologies to the future.
