Particle accelerators are experimental techniques and associated infrastructures that use electromagnetic fields to accelerate charged particles, such as electrons, protons, or heavy ions, to high kinetic energies and control their trajectories for collision, beam-target, or irradiation experiments. They employ radiofrequency cavities, electrostatic fields, and magnetic optics (dipole, quadrupole, and higher-order magnets) to shape, focus, and steer beams with precise energy, emittance, and luminosity characteristics. As techniques, accelerators enable probing of fundamental interactions in high-energy physics, production of secondary particles (e.g., neutrons, mesons, synchrotron radiation), and finely controlled irradiation or imaging in materials science, nuclear physics, and medical and industrial applications.
The next head of Europe's CERN physics laboratory said Thursday that he favored moving forward with plans for a giant particle collider far more powerful than the collider that discovered the famous "God particle".
