Particle accelerators, machines that propel electrically charged particles to high speeds to increase their kinetic energy, are among the principal tools of science. Researchers at Berkeley Lab’s Accelerator Technology and Applied Physics Division focus on concepts, strategies and designs to improve the state of accelerator science and technology.
