Abstract
The greatest developments in particle physics have been achieved with the help of particle accelerators. To answer open questions on particles, even stronger accelerators are needed but conventional technology encounters limits. The new ‘plasma-wakefield acceleration’ technology is designed to build high performance accelerators that are more compact. As ALLEN CALDWELL explains, the basic idea is to generate a plasma wave that pushes the particles forward. As is shown in this video, energizing the plasma with a proton beam instead of a laser pulse allows to create an electric field of much longer distance.
