Development and evaluation of novel, large area, radiation hard silicon microstrip sensors is necessary for the operation of the ATLAS detector at the high luminosity upgrade of the LHC particle accelerator. This next-generation collider will allow an order of magnitude more premier physics data to be obtained from the facility that produces the world-leading 13 − 14T eV centre-of-mass frame collisional energy. The physics impact of this cou- pled nature is fundamental as the sensitivity to any interaction that falls within this massive energy range is naturally increased by the reduction in statistical uncertain- ties. This poses two prime opportunities for the discovery of new physics; precision measurement of known interactions and sensitive uncovering of the unknown. The HL-LHC’s increases in collision rate and experiment lifetime necessitate com- plimentary changes to the LHC detectors’ layouts, granularities, readouts, and radia- tion hardness. For the general purpose ATLAS detector the ...
