 Chandrashekhar Janardan Joshi
(2022-09-25)  Wakefield  linear accelerators  (Joshi, 2003)
Acceleration of charged particles in plasma using lasers.

The basic idea is to let charged particles surf the wakes of the wave produced in a plasma by a laser beam.  This was proposed in 1979 by  Toshiki Tajima (1948-)  and  John M. Dawson (1930-2001).  It was first realized experimentally by Tajima in 1994.  The technique has been perfected at UCLA since 2003 by the group led by  Chan Joshi.  Nowadays,  every major accelerator facility is planning a  wakefied  booster upgrade.
