Swapan Chattopadhyay

Chattopadhyay is 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.^[10][11] He has directly contributed to the development of many accelerators around the world, e.g. the Super Proton-Antiproton Synchrotron at CERN,^[9] the Advanced Light Source at Berkeley,^[12] the asymmetric-energy electron-positron collider PEP-II at Stanford,^[13] the Continuous Electron Beam Accelerator facility (CEBAF) at Jefferson Lab and the Free-Electron Lasers at Jefferson and Daresbury Laboratories.^[14]

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.^[15][11] In this role he was the Inaugural Director of the Cockcroft Institute (UK), having been appointed in April 2007. Prior to this he served as associate director of Thomas Jefferson National Accelerator Facility (2001–2007),^[16] staff/senior scientist and founding director of the Centre for Beam Physics at Lawrence Berkeley National Laboratory (1984–2001); and scientific attaché at CERN (1982–1984).^[17]

After the period spent at CERN, Chattopadhyay returned to Lawrence Berkeley National Laboratory in 1984, where he led and defined the accelerator physics of the Advanced Light Source (ALS)^[12] and contributed to the conceptual design of the Superconducting Super Collider (SSC),^[18] pioneered the accelerator physics which underpinned the Berkeley-Stanford asymmetric B-factory (PEP-II) for CP-violation studies, and initiated the Berkeley FEL/Femtosecond X-ray Source and Laser-Plasma Acceleration development. He was a senior scientist, a guest professor, and the founder/director of the Center for Beam Physics at Berkeley,^[19] until his move to Thomas Jefferson National Accelerator Facility in 2001 as the associate laboratory director for accelerators. At Thomas Jefferson National Accelerator Facility, he made critical advancements in microwave superconducting linear accelerators leading the way to current and future grand instruments of science such as the high precision CEBAF and its 12 GeV upgrade for precision research in hadronic physics,^[20] Spallation Neutron Source at Oak Ridge National Laboratory, USA to advance neutron sciences and novel materials research, and the current superconducting version of the International Linear Collider, to name a few. His research at the Cockcroft Institute in UK included development of sources of "ultra-cold" relativistic free electron beams to advance coherent electron diffraction techniques; production of novel coherent and ultra-short pulses of photons (e.g. x-ray FELs); novel acceleration methods; investigation of photonic crystals and metamaterial structures for charged particle acceleration; novel high energy colliders.

While working for Fermilab and Northern Illinois University he contributed to cavity searches for dark matter; investigation of ultra-light dark matter and dark energy via atom interferometry, and the creation of the Matter-wave Atomic Gradiometer Interferometric Sensor (MAGIS-100) experiment.^[21][22] Having contributed to the conception, design, construction, commissioning and operation of numerous accelerators for particle and nuclear physics, photon and neutron sciences around the world, with significant research accomplishments in advanced particle and photon beam physics,^[23][24] and mentoring scientists around the world, in the developing nations in particular, in accelerator developments as a unifying global force among nations, Swapan Chattopadhyay is a frequently invited speaker and advisor at professional societies and government research agencies, serving on numerous editorial, advisory and review committees throughout the world.

He served as the Vice-Chair, Chair-elect, Chair and Past-Chair of the American Physical Society's Division of Physics of Beams (2007–2011). Chattopadhyay has delivered lectures throughout the world e.g. Saha Memorial Lecture,^[25] Homi Bhabha Lecture, Raja Ramanna Memorial Lecture, and Cavendish Lecture among many.
