Silicon Tracker Endcap for the upgraded CMS experiment at the High-Luminosity LHC at CERN.

Scientific curiosity drives us to explore the largest as well as the smallest structures around us. With its 27 km circumference the Large Hadron Collider at CERN collides protons at the highest energies to study the most fundamental building blocks of matter. The recent discovery of the Higgs particle by the ATLAS and CMS experiments was awarded internationally. As a consequence the particle physics community worldwide assigns the top priority to further explore the properties of the Higgs particle as well as to extend our search for new physics phenomena. From 2026 onwards the High-Luminosity LHC will be operational at CERN delivering a 10 times larger dataset of proton collisions to the physicists. This requires the construction of adequate and typically novel detector systems. The Belgian experimental particle physics groups are skilled and motivated to continue their research and leadership in the CMS experiment. The Tracker System is the main system to be innovated and replaced. This Hercules application embraces the construction by the Belgian teams of one Tracker Endcap. This exceptional equipment will be the basis of our research for the next 2 decades.
