John Corlett

accelerator physicist: Accelerator and Fusion Research Division

Paul Preuss, 510-486-6249,

Lynn Yarris, 510-486-5375,


John Corlett is head of Accelerator Systems for Future Light Sources in Berkeley Lab’s Accelerator and Fusion Research Division, at the forefront of developing new concepts and new technologies for high-energy particle accelerators and for synchrotron and accelerator-based light sources. One of Corlett’s special interests is designing next-generation, coherent x-ray sources of the kind known as free electron lasers (FELs).

Corlett joined Berkeley Lab in 1991 after five years at the Daresbury Laboratory’s Synchrotron Radiation Source in England. He has played key roles in projects for Berkeley Lab’s Advanced Light Source, the PEP-II B-factory at SLAC, cooling ring designs for the proposed International Linear Collider, muon cooling designs for a proposed muon collider, and designs for a next generation light source. His research includes FELs, accelerator modules, high-brightness electron beams, feedback and collective effects, and optical systems for diagnostics, control, and synchronization of accelerator systems and components.
