Traditionally, particle accelerators have relied on electric fields generated by radio waves to drive electrons and other particles close to the speed of light. But in radio-frequency machines there is an upper limit on the electric field before the walls of the accelerator "break down," causing it to not perform properly, and leading to equipment damage.
In recent years, however, scientists experimenting with so-called "plasma wakefields" have found that accelerating electrons on ...
