Prof. Jones is the Head of the Accelerator Physics Group at the University of Manchester. For more than a decade he has been leading his own personal team of half a dozen Ph.D. students and postdoctoral researchers focussed on Very High Energy Electron (VHEE) studies with application to FLASH radiotherapy. This has entailed ground breaking experiments on dose studies and DNA damage at CERN and Daresbury Laboratory, and on simulations of dose deposition and DNA damage. Prior to his VHEE work Prof. Jones was pursuing research on on linear colliders (LC) in collaboration with CERN, KEK, Fermilab and LLNL whilst a senior scientist at SLAC (part of Stanford University). This research entailed a global effort focussed on building a necessarily robust and stable machine capable of delivering a center of mass energy of 3 TeV –achieved using several thousand linac structures. Some of the recent work of his current VHEE team entails designing a medical machine capable of rapidly delivering high dose rates at 250 MeV for radiotherapy – capitalising on LC research which in this though case only requires a small fraction of the several thousand linacs needed for particle physics. Prof. Jones will review some key results in VHEE with application to FLASH radiotherapy and discuss the potential for future R&D in this area.
