Geoff Hall's research has mainly been concerned with novel electronic instrumentation for elementary particle physics experiments, motivated originally by the need for high spatial precision detectors to measure the properties of then recently discovered charmed particles. He has focused for thirty years on the CMS experiment at the CERN Large Hadron Collider, where he contributed significantly to the complex detector systems essential for the discovery of the Higgs boson in 2012.
Radiation damage induced by particle fluxes at the LHC has been a constant challenge, including for future operations in even more stringent conditions. Innovations initiated by Geoff have allowed CMS to create an unprecedentedly powerful particle tracking detector, and will soon use its data in real time event selection for the first time to substantially improve searches for new and rare physics. Several of his team’s developments have been exploited throughout the world, beyond the LHC.
He was awarded the Duddell medal of the Institute of Physics in 2005 and the Chadwick medal in 2020.
