Researchers have successfully activated the world's smallest particle accelerator, called a nanophotonic electron accelerator (NEA). It uses miniature laser beams to accelerate electrons, marking a departure from traditional particle accelerator technology. In a recent study, researchers reported a 43% increase in energy using the NEA. The goal is to develop miniature accelerators for precise medical treatments, such as administering radiotherapy directly to affected areas in the body.Researchers have successfully activated the world's smallest particle accelerator, called a nanophotonic electron accelerator (NEA).
