In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term – the metal is ...

Laser plasma acceleration is a potentially disruptive technology: It could be used to build far more compact accelerators and open up new use cases in fundamental research, industry and health.

With dual lasers, researchers have accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters. The experiment gives scientists a 'frame-by-frame' look at how a ...

Experts at the BELLA Center used dual laser beams focused onto a sheet of gas to reach a milestone energy in laser-driven electron acceleration. Four members of the larger team gathered with the ...
