The ANU team not only succeeded
in building the
experiment, which seemed nearly impossible when it was proposed
in 1978, but reversed Wheeler's original concept of light
beams being bounced by mirrors, and instead
used atoms scattered by laser light.

use the
beam for
experiments.
CERN's antimatter factory makes antiprotons — the rare mirror image of protons — by slamming a proton
beam into a metal target, then dramatically slowing the emerging antiparticles so they can be
used in experiments.
Thanks to the particular geometry of the microsphere target
used in these
experiments, the impact of the laser
beam produces a plasma whose properties would be virtually impossible to reproduce by bombarding a foil target.
Berkeley Lab was home to a pioneering

in 2004 that showed laser plasma acceleration can produce relatively narrow energy spread
beams - reported

in that they found the formation rate of aerosol increased
in the presence of ions generated
using a 580 MeV electron
beam (Enghoff et al. 2011).
