# Ilan Ben-Zvi

Ilan Ben-Zvi (Hebrew: אילן בן צבי) 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 "Dieter Möhl Awards 2023". Cool Conference 2023 (CERN). 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.

## Early life and education

Ben-Zvi completed his Bachelor's in Physics and Mathematics at the Hebrew University of Jerusalem. In 1970, he obtained a Ph.D. in Physics from the Weizmann Institute of Science under the supervision of Gvirol Goldring.

## Scientific career

Ben-Zvi worked on a very broad front of accelerator and beam physics and in a large number of universities, national laboratories and particle accelerators. He worked on accelerator physics of superconducting radio frequency (SRF) at Stanford University, where he developed the superconducting reentrant cavity and beam dynamics of heavy ion linacs. At the Weizmann Institute of Science he developed accelerator elements such as a chopper-buncher system for an electrostatic accelerator. At the Laboratori Nazionali di Legnaro Ben-Zvi introduced the SRF QWR, enabling the APLI machine. At DESY he developed the current leads for the superconducting HERA (particle accelerator). At Stony Brook University as a Visiting Associate Professor (1980-1982) he was on a team building a superconducting heavy ion linac and developed the first superconducting Quarter Wave Resonator (QWR). At the University of Washington he worked on new types of Quarter Wave Resonators, superconducting resonator controllers and cryostats.Again at Stony Brook 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 APLI. Ben-Zvi served as a BNL Professor at Stony Brook University from 2010 to 2020. At Brookhaven National Laboratory 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. At this facility he 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, laser photocathodes and on developing electron cooling for the RHIC collider, as well as carry out research and development for the Electron-Ion Collider. At CERN he initiated the double quarter wave crab cavity, self-excited loop cavity control system and ferroelectric fast reactive tuners.
