Particle accelerators have become crucial tools for understanding the fundamental nature of our universe, but they are incredibly big and expensive. One of the most impressive aspects of particle accelerators used for research such as the Large Hadron Collider (LHC) at CERN is their physical size. Yet, even with a circumference of 27 km LHC would be smaller than the next proposed colliders. The International Linear Collider (ILC) project, which is designed to collide electron and positrons, could be 31 km long, even smaller than the Future Circular Collider (FCC) with a circumference of 80 km. Both accelerators rely on Radio Frequency cavities providing the energy to the beam. This technology has limits which lead to very long and costly machines. That could change, though, after scientists have validated a new approach that could lead to a generation of smaller, more powerful accelerators, using Plasma Wakefield acceleration providing GeV/m accelerating gradients. The new developments may open the future to ultra-small compact accelerators for industry and medical applications.
