Imperial College London Accelerator Group is a research collective within Imperial College London focused on the design, development, and application of particle accelerators and advanced beam technologies. The group collaborates with national laboratories, industrial partners, and international consortia to advance accelerator science, contribute to large-scale projects, and train researchers and engineers. It engages with projects ranging from synchrotrons and free-electron lasers to compact accelerators and medical therapy facilities.

History

The Accelerator Group traces roots to teaching and research initiatives at Imperial College London and collaborations with the CERN community, the Science and Technology Facilities Council, and the United Kingdom Atomic Energy Authority. Early personnel included alumni who had worked at Cavendish Laboratory, Royal Society fellows, and researchers transitioning from projects like the Large Hadron Collider, the Diamond Light Source, and the ISIS Neutron and Muon Source. The group built on partnerships with the Engineering and Physical Sciences Research Council, the European Organization for Nuclear Research, and the Rutherford Appleton Laboratory to contribute to beamline design, magnet development, and RF system research. Over decades it engaged with initiatives connected to the European XFEL, the MAX IV Laboratory, and the Spallation Neutron Source, supporting technology transfer to industry partners including Siemens, Thales Group, and Oxford Instruments. Key moments included contributions to upgrade studies for the Large Electron–Positron Collider successors, involvement in plasma wakefield experiments inspired by work at SLAC National Accelerator Laboratory, and educational exchanges with the Paul Scherrer Institute and the Deutsches Elektronen-Synchrotron.

Mission and Research Focus

The group's mission emphasizes advancing accelerator science, enabling applications in medical physics, materials science, and photon science. Research areas include beam dynamics studies influenced by methods used at Fermilab, development of superconducting radiofrequency (SRF) cavities reminiscent of designs at Jefferson Lab, and exploration of compact accelerator concepts paralleling efforts at Lawrence Berkeley National Laboratory. Projects examine wakefield acceleration techniques informed by experiments at FACET-II, novel magnet designs akin to developments at Brookhaven National Laboratory, and accelerator control systems that reference standards from ITER diagnostics. The group supports translational work for proton therapy modeled on implementations at The Christie NHS Foundation Trust and radiotherapy centers associated with Mount Vernon Cancer Centre.

Facilities and Technology

Facilities supporting the group include laboratory space at South Kensington, London and access to test stands and fabrication workshops in collaboration with Rutherford Appleton Laboratory and Daresbury Laboratory. Equipment inventories align with international programs, featuring RF test benches comparable to those at DESY, superconducting magnet test facilities like those at CERN partner institutes, and diagnostic tools used by teams at the European Synchrotron Radiation Facility. The group develops beam instrumentation technologies parallel to those at ITER, vacuum systems reminiscent of Brookhaven National Laboratory practice, and laser systems akin to installations at Central Laser Facility. Collaborative access extends to beamlines at Diamond Light Source, cryogenic facilities reflecting standards at Max Planck Institute for Physics, and microfabrication resources coordinated with National Physical Laboratory.

Academic Programs and Training

Academic programs include postgraduate supervision, hands-on training, and short courses similar to training offered at CERN School of Accelerators, the John Adams Institute for Accelerator Science, and the Cockcroft Institute. The group contributes modules to degree programs in collaboration with departments such as Department of Physics, Imperial College London, and runs internships linked to the Royal Academy of Engineering Industrial Fellowships and the Marie Skłodowska-Curie Actions. Students engage with international exchanges with institutions like École Polytechnique, ETH Zurich, and University of Oxford, and participate in projects funded by the European Research Council and the Royal Society.

Industry Partnerships and Commercialization

Industry partnerships involve technology transfer and joint development with companies including Siemens Healthineers, Varian Medical Systems, Oxford Instruments, Thales Group, and smaller spinouts derived from university intellectual property. The group supports commercialization paths following models used by the European Space Agency spinout program and engages with innovation networks such as Knowledge Transfer Network and UK Research and Innovation. Collaborative projects have targeted compact accelerator systems for security screening adopted by suppliers to Heathrow Airport infrastructure and medical accelerator components for suppliers to cancer centers like Royal Marsden, with regulatory interfaces referencing standards from Medicines and Healthcare products Regulatory Agency.

Notable Projects and Achievements

Contributions include participation in upgrade design studies for Large Hadron Collider injector systems, involvement in plasma wakefield experiments echoing milestones at SLAC National Accelerator Laboratory and AWAKE, and work on superconducting cavity prototypes relevant to European XFEL technology. The group has collaborated on beam diagnostic innovations used in synchrotron facilities such as Diamond Light Source and contributed to magnet designs tested at Rutherford Appleton Laboratory. Graduates have joined teams at CERN, Fermilab, DESY, and industrial employers including Siemens and Oxford Instruments. Recognition includes project funding from the Engineering and Physical Sciences Research Council and awards aligned with schemes from the Royal Society and the Institute of Physics.
