An international team of physicists, working on the Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) at CERN, reported that they have conducted a groundbreaking experiment demonstrating a new way of accelerating electrons to high energies -- one that could dramatically shrink the size of future particle accelerators and lower their costs. A paper describing this important result was published in Nature on August 29, 2018.
"AWAKE's technology will bring about a paridigm shift in the development of future high-energy particle accelerators, following LHC," says Professor Chung. "The latest achievement could enable engineers to drastically reduce the size of future particle accelerators, cutting down on the vast amounts of money normally required to build them." He adds, "The high-energy particle collisions these facilities produce enable physicists to probe the fundamental laws of nature, providing the basis for advancements in a huge variety of different fields."
Typically, particle physics experiments use oscillating electric fields, called radiofrequency cavities, and high-powered magnets to accelerate particles to high energies. But these experiments must grow quite large -- they have to be, in order to accelerate particles with enough energy to properly study them.
