(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.
