Berkeley Lab was home to a pioneering experiment) in 2004 that showed laser plasma acceleration can produce relatively narrow energy spread beams - reported in the so - called «Dream Beam» issue of the journal Nature - and in 2006 used a similar laser - driven acceleration technique to accelerate electrons to a then - record energy of 1 billion electron volts, or GeV.
