Description The Large Hadron Collider has made a great scientific and social impact. The Higgs boson discovery has opened a new window into our understanding of the university and has captured people's imagination. The potential for even further discoveries at the LHC is high.

To remain on the forefront of discovery, the LHC and its experiments need a series of upgrades to manage the harsh environment. This grant is the current in a series of grants to support the Phase II upgrade of the silicon tracker of the ATLAS experiment, which is expected to install in 2022-2023. The tracker will take "pictures" of the trajectories of charged particles created by the collisions of protons every 25 ns.

This grant supported ATLAS upgrade work within the Liverpool Semiconductor Detector Center (LSDC) and Physics Workshop. In the workshop, common tooling necessary for the production of barel hybrids and modules for both the ATLAS pixel and strip system was prototypes and produced for our more than 15 national and international collaborating institutes. Parts of the common tools for the production of strip staves were also produced in the workshop. Tooling for the production of prototypes for development of the pixel end cap supports and the barrel strip interlinks were also produced.

Within the LSDC, the first strip hybrid and module prototypes were produced and evaluated. These tests allowed for parts to made for the rest of the collaboration with confidence. Similarly, hybrid and module prototype were produced for the pixel end cap. Finally, the mechanical stablity of strip barrel stave and pixel end cap global supports was tested.
Exploitation Route The development of radiation hard sensors will be useful for medical physics (proton therapy, amongst others) and nuclear material monitoring, as well as future nuclear and particle physics experiments.

The developments needed for light, carbon-fibre structures for the upgrade have been used in other departments in the University. In particular, the mechanical engineering formula student program has made a number of components using our techniques.
