Wakefield accelerators

Plasma models get a boost

Laser-driven particle accelerators can accelerate electrons to energies in excess of 1 GeV over a distance of just a few centimetres. An innovative technique that drastically reduces the computational demands of simulating laser–plasma interactions should help increase this to tens of gigaelectronvolts.
