Energy doubling of 42 GeV electrons in a metre-scale plasma wakefield accelerator
Plasma-based particle accelerators are particularly attractive as they are capable of producing accelerating fields orders of magnitude larger than those used in conventional colliders. In an experiment run at...

Refraction of a particle beam
The refraction of light at an interface is familiar as a rainbow or the 'bending' of a pencil in a glass of water. Here we show that particles can also be refracted and even totally internally reflected, as ev...
