Swapan Chattopadhyay CorrFRSE (born December 26, 1951) is a particle accelerator physicist noted for his pioneering contributions of innovative concepts, techniques and developments in high energy particle colliders, coherent and incoherent light sources, ultrafast sciences in the femto- and atto- second regimes, superconducting linear accelerators and various applications of interaction of particle and light beams.
He has directly contributed to the development of many accelerators around the world, e.g.
the Super Proton-Antiproton Synchrotron at CERN, the Advanced Light Source at Berkeley, the asymmetric-energy electron-positron collider PEP-II at Stanford, the Continuous Electron Beam Accelerator facility (CEBAF) at Jefferson Lab and the Free-Electron Lasers at Jefferson and Daresbury Laboratories.
Currently, Chattopadhyay holds the Presidential Chair of Research, Scholarship and Artistry at Northern Illinois University (NIU) where he is Professor of Physics and Director of Accelerator Research.
Concurrently he holds a joint appointment with Fermi National Accelerator Laboratory (Fermilab) where he is a distinguished scientist, member of the director's senior leadership team and director of the Cooperative Research and Development Agreement between Fermilab and NIU.
He was formerly the Sir John Cockcroft Chair of Physics jointly at the Universities of Liverpool, Manchester and Lancaster—the First Chair of accelerator physics in UK, named after the British Nobel Laureate credited with creating the field.
In this role he was the Inaugural Director of the Cockcroft Institute (UK), having been appointed in April 2007.
in Physics from University of California at Berkeley in 1982.
He had held Visiting Professor appointments at University of California at Berkeley, Harvard University, University of Illinois at Urbana Champagne and University of Virginia at Charlottesville at various times.
He is a Fellow of the American Physical Society, American Association for the Advancement of Science, Institute of Physics (UK), Royal Society of Arts, Manufactures and Commerce (UK) and Corresponding Fellow of the Royal Society of Edinburgh and a member of many international panels and committees, including the "International Committee for Future Accelerators" and the DESY Science Council.
He had served as the Vice-Chair, Chair-elect, Chair and Past-Chair of the American Physical Society's Division of Physics of Beams (2007–2011).
He has mentored many scientists and engineers across the globe including Asia, North America and Europe and has delivered endowed lectures throughout the world e.g.
Saha Memorial Lecture, Homi Bhabha Lecture, Raja Ramanna Memorial Lecture, and Cavendish Lecture among many.
