Strong focusing refers to a technique used in particle accelerators to keep particles on their desired path and ensure maximum efficiency in colliding with other particles. Synonyms for strong focusing include beam focusing, particle guiding, and particle steering. These terms refer to the same technique, but highlight different aspects of the process. For example, particle steering refers to the control of the particle beam's trajectory in a specific direction, whereas beam focusing emphasizes the concentration of the particles in a specific area. Nevertheless, all of these terms ultimately describe the same process that is used to optimize the performance of particle accelerators and support scientific research and discovery.
