Rosenzweig, J.

James Benjamin Rosenzweig is an experimental plasma physicist and a distinguished professor at the University of California, Los Angeles (UCLA). In the field of plasma wakefield acceleration, he is regarded as the father of the non-linear "blowout" interaction regime, where a laser beam, when fired into a plasma at intense levels, expels electrons from the plasma and creates a spherical structure that can effectively focus and accelerate the plasma. Rosenzweig's research on accelerator technologies and light source development is also considered to be pioneering in the field. For his research on plasma acceleration and electron beams, Rosenzweig was inducted as a fellow of the American Physical Society in 1998. He is the recipient of the 2007 Free Electron Laser (FEL) Prize, 2022 Advanced Accelerator Prize, and the 2023 Hannes Alfvén Prize.
