Ilan Ben-Zvi

Ilan Ben-Zvi is an accelerator physicist and academic. He was the associate chair for accelerator R&D at the Collider-Accelerator Department (C-AD) and is a distinguished scientist emeritus at the Collider-Accelerator Department (C-AD) at Brookhaven National Laboratory.

Ben-Zvi is most known for his work on accelerator physics, experimental physics, and beam physics. He has authored or co-authored over 650 papers. Ben-Zvi was awarded the 2007 Free-electron laser Prize for his contributions to the field of Free-Electron Lasers. In 2023 he was given the Dieter Möhl Medal for his outstanding contributions to the development of high-energy electron cooling. Ben-Zvi is a Life Fellow of the Institute of Electrical and Electronics Engineers. , a cavity geometry since adopted at low-velocity SRF linacs worldwide. He subsequently contributed to the superconducting heavy-ion booster at the University of Washington on new types of Quarter Wave Resonators, superconducting resonator controllers and cryostats. At the Laboratori Nazionali di Legnaro Ben-Zvi introduced the SRF QWR, enabling the ALPI machine. At DESY he developed the current leads for the superconducting HERA (particle accelerator).

Returning to Stony Brook University as a Visiting Professor (1988-1990) he developed the first SRF Radio Frequency Quadrupole, which was tested and formed the basis for the PIAVE injector of ALPI.

Ben-Zvi joined Brookhaven National Laboratory in 1988, receiving tenure in the National Synchrotron Light Source in 1991. There he led the construction of the Accelerator Test Facility (ATF), originally established by Robert Palmer and Claudio Pellegrini, served as its director for fifteen years and eventually elevated it to a United States Department of Energy National User Facility. From 2005 to 2018 he was Associate Chair for Accelerator R&D of BNL's Collider-Accelerator Department, and he was appointed Distinguished Scientist Emeritus in 2018. He served as a BNL Professor at Stony Brook University from 2010 to 2020.

At the ATF Ben-Zvi pioneered laser acceleration of particles, advanced beam instrumentation and laser-beam interactions. He also led various aspects of Free-electron laser, including the High-Gain Harmonic Generation FEL, high brightness electron sources, and laser photocathodes. Other projects include developing electron cooling for the RHIC collider, as well as carry out research and development for the Electron-Ion Collider.

Ben-Zvi invented the double quarter wave crab cavity, and led the team which built and tested its first prototype. This cavity is now part of the luminosity upgrade of the LHC.

On Sabbatical leave at CERN (2016-2018) Ben-Zvi tested superconducting cavities. developed self-excited loop cavity control system and ferroelectric fast reactive tuners.

Community service

Ilan Ben-Zvi served the accelerator and beam physics community in various capacities. Some examples follow:

At the Division of Physics of Beams of the American Physical Society he Served as the Secretary-Treasurer from 1999 to 2002, was a member of the committee which established the journal Physical Review Accelerators and Beams (PR-AB), then served on the inaugural Editorial Board of PR-AB and as Divisional Associate Editor for Physical Review Letters, from 2010 to 2016. PR-AB At the Institute of Electrical and Electronics Engineers Nuclear and Physics Plasma Society (NPSS) Ben-Zvi Served as Chair, Particle Accelerator Science and Technology Committee, of the NPSS from 2005 to 2009. In this capacity he established the Particle Accelerator Science and Technology Doctoral Student Award and served as chair of its prize committee from 2008 for ten years. He also chaired the NPSS Particle Accelerator Science and Technology Award Committee starting in 2005 for thirteen years, Member, IEEE Marie Sklodowska-Curie Award Committee, 2014 – 2016 and Chair of same Committee, 2017-2019. Ilan Ben-Zvi served on various national advisory committees: Member, National Academy of Sciences Committee for the Scientific Assessment of High-power Free-electron laser Technology, 2007-2008, member, High Energy Physics Advisory Panel, United States Department of Energy, 2013-2015. Ben-Zvi served on various international committees: Member, Advisory Committee on TRIUMF, National Research Council Canada, 2013-2015, chair of the FLASHForward Scientific Advisory Board,DESY 2014-2017 and member, DESY (Hamburg) Machine Advisory Committee, 2019-2020, and at Laboratori Nazionali di Legnaro on the International Advisory Committee on the APLI Positive Ion Injector, in 1996 as Chair and in 1997 as member, at Daresbury Laboratory as member, Cockcroft Institute Science Advisory Committee from 2006 to 2009. In 1996/1997, Ben-Zvi came up with the idea for the archival of accelerator conference proceedings on the World Wide Web, later to become known as JACoW, for Joint Accelerator Conferences Website. Ben-Zvi gathered representatives of the US, European and Asian particle accelerator conferences in a committee that launched JACoW. JACoW became a major community resource.
