Accelerator physics is the study of how to design and operate particle accelerators, which are machines that propel charged particles, like electrons and protons, to high speeds. These accelerators are used in various fields, including high-energy physics, medical applications, and materials science, to explore fundamental questions about matter and energy. In accelerator physics, researchers focus on understanding the behavior of particles as they travel through electromagnetic fields. This involves calculating trajectories, optimizing beam quality, and ensuring safety. Notable facilities, such as the Large Hadron Collider (LHC), rely on these principles to conduct experiments that advance our knowledge of the universe.
