Linear accelerators (a subcategory of particle accelerators) are essential tools used for fundamental research and practical applications, including particle and nuclear physics, energy production, chemistry, materials and biological sciences, and medicine. Beams of electrons, protons, and many other particles can be generated, requiring a diversity of different accelerator structures. Scientists continue to build higher energy and higher current linear accelerators, making use of and often pushing the progress in many technological fields like high-power radiofrequency sources, precision mechanics, high vacuum, magnetics, superconducting materials, wideband electronics, digital controls, and precision civil engineering.
