The new technique, created by researchers at Imperial College London with collaborators in Japan and Germany, will help deliver beams of ions that could treat cancers with high doses of more targeted radiation.
Particle accelerators use electric fields to accelerate a range of particles, such as ions. They have been developed and used for over a century, to both conduct fundamental studies and treat cancers in hospitals. Recently, new methods that involve lasers manipulating electrons inhave been developed, which create electric fields millions of times larger than those possible in standard machines.
These techniques allow accelerators to be much smaller and to deliver ultrashort ion beams only nanoseconds long. This is particularly useful for cancer radiotherapy, allowing targeted treatment that leaves more healthy tissue intact., shows how to get copious high-energy ions out of these accelerators.

The system works by firing a laser at a plasma to accelerate it and create the electric field. However, usually the plasma is opaque to light, meaning the laser only interacts with the plasma surface that it first strikes before bouncing off.
