Accelerator and Beam Physics Group is a research collective focused on the design, modeling, commissioning, and operation of high‑energy and applied accelerators. The group integrates expertise in beam dynamics, accelerator physics, superconducting technology, and diagnostics to support projects at national laboratories, universities, and industry partners. Its work underpins experimental programs in particle physics, synchrotron light sources, free‑electron lasers, medical therapy, and materials science.
The group's roots trace to collaborations among institutions such as CERN, Fermilab, SLAC National Accelerator Laboratory, DESY, and Brookhaven National Laboratory, with early influences from pioneers like Ernest Lawrence, Enrico Fermi, E. O. Lawrence Radiation Laboratory, and developments at Los Alamos National Laboratory. Milestones include contributions to the Large Hadron Collider, Tevatron, Stanford Linear Accelerator Center, and upgrades tied to European XFEL and KEK. Interactions with projects at Argonne National Laboratory, INFN, Rutherford Appleton Laboratory, Paul Scherrer Institute, and TRIUMF shaped techniques in beam optics and accelerator control. The group’s methods evolved alongside achievements at Bell Labs, MIT, Caltech, University of Oxford, and Imperial College London.
Research spans beam dynamics, collective effects, and nonlinear optics informed by studies from John Adams projects and concepts used at Proton Synchrotron facilities. Work includes lattice design influenced by Synchrotron Radiation Source developments, space‑charge compensation relevant to programs at ISIS Neutron and Muon Source, and wakefield studies connected to AWAKE and FACET. Accelerator physics modeling leverages algorithms derived from software histories at Madison Symmetric Torus, NERSC, Lawrence Berkeley National Laboratory, and large simulations developed for ITER and International Linear Collider. Beam instrumentation efforts borrow methodologies from Diamond Light Source, MAX IV Laboratory, SPring-8, and National Synchrotron Light Source II.
The group deploys diagnostics such as beam position monitors used at Advanced Photon Source, beam loss monitors common to Spallation Neutron Source, and halo monitors like those at Paul Scherrer Institut. It designs superconducting RF systems applied in European Spallation Source, cryomodules similar to Jefferson Lab installations, and high‑power RF sources akin to devices at Los Alamos National Laboratory. Test facilities include injector test stands modeled on ELI, beam test areas inspired by CERN Proton Synchrotron Booster, and cryogenic labs comparable to DESY Hamburg. Instrumentation development often collaborates with groups from Oxford Instruments, Thales Group, General Atomics, and university labs such as University of California, Berkeley and Stanford University.
Collaborative networks encompass programs with CERN, DOE Office of Science, European Commission, ITER Organization, and consortia like International Linear Collider partners. Industry collaborations include Siemens, Hitachi, Varian Medical Systems, and Toshiba for accelerator components and medical applications. Academic partners range from University of Manchester, ETH Zurich, University of Tokyo, Tsinghua University, Seoul National University, to University of Melbourne. The group engages with international projects such as ITER, European XFEL, Compact Linear Collider, and accelerator initiatives at Brookhaven National Laboratory and Fermi National Accelerator Laboratory.
Training efforts include graduate and postdoctoral programs connected to CERN Summer Student Programme, US Particle Accelerator School, Cockcroft Institute, and doctoral schools at University of Oxford and University of Cambridge. Short courses draw on curricula from KAIST, EPFL, University of California, Los Angeles, and mentorship models employed at Stanford Linear Accelerator Center. Outreach includes workshops at IEEE Particle Accelerator Science and Technology Conference, tutorials for American Physical Society meetings, and exchanges with International Union of Pure and Applied Physics initiatives.
Notable outputs include contributions to accelerator design reports for Large Hadron Collider, conceptual designs for International Linear Collider, and technical notes influencing European XFEL commissioning. Publications appear in journals and proceedings associated with Physical Review Special Topics - Accelerators and Beams, Nuclear Instruments and Methods in Physics Research Section A, and conference series like International Particle Accelerator Conference and Beam Instrumentation Workshop. Influential technical achievements echo methods used in betatron tune control pioneered in facilities like CERN ISR and beam cooling strategies related to Stochastic Cooling advances at CERN and Fermilab.
The group typically organizes into subteams for lattice design, RF systems, diagnostics, operations, and theory, modeled after divisions at Brookhaven National Laboratory, Argonne National Laboratory, and Lawrence Berkeley National Laboratory. Funding sources include grants from U.S. Department of Energy, European Research Council, national science agencies such as National Science Foundation, STFC, Agence Nationale de la Recherche, and industry contracts with companies like Siemens and General Atomics. Long‑term projects often operate under memoranda of understanding with laboratories including CERN, DESY, KEK, and Fermilab.
