The discovery of the Higgs Boson at the LHC by the ATLAS and CMS experiments has been a major success, however evidence for new physics has remained elusive. The High Luminosity Upgrade of the LHC (HL-LHC) will extend the reach for new physics and deepen our understanding of the newly found Higgs Boson. The recently published European Strategy for High Energy Physics has therefore given the HL-LHC Upgrade the highest priority. The unique technological challenges of designing and constructing the new ATLAS Silicon Strip Tracker to cope with the unprecedented data rates require novel approaches. Developing advanced silicon modules that can withstand the radiation levels at the HL-LHC is key to the success as is the reduction of insensitive material inside the tracking volume.

The Helmholtz centre DESY and the CAS partner IHEP have decided to team up to work on these key issues, which need to be addressed to make the silicon strip tracker upgrade a success. An extensive study of radiation damage of silicon modules is foreseen as are the development of advanced low-voltage and high-voltage powering schemes. Understanding the thermal properties of novel materials used in constructing these modules is another step-stone towards the successful construction of such a tracker.

Each partner brings its unique expertise into this new collaboration as both are Major players in high-energy physics and have a proven track record. The initial investment into this proposed collaboration is envisaged to seed a long-standing close collaboration between both DESY and IHEP. The project will train the next generation of Young scientists, providing hands-on experience and profound understanding of silicon detector systems. Furthermore it will also foster the international cooperation between the Partners and continue to provide highly skilled people not only for high-energy physics, but likewise for academia and industry in general.
