Protons and deuterons are charged particles that, when accelerated to high speeds in particle accelerators, serve as energetic projectiles used to induce nuclear reactions and study subatomic interactions.12

  • Protons: As the nuclei of hydrogen atoms, protons are typically generated by ionizing hydrogen gas or stripping electrons from negative hydrogen ions. In accelerators, they are guided by magnetic fields and accelerated by electric fields to high velocities. As they approach the speed of light, relativistic effects become significant; their mass increases, requiring stronger magnetic fields to maintain their circular orbits in synchrotrons.342
  • Deuterons: These are the nuclei of deuterium (heavy hydrogen), consisting of one proton and one neutron. Like protons, they are produced by ionization and are accelerated to high energies to act as projectiles in nuclear research.1

When these high-speed particles strike targets or collide with other beams, they can deform nuclei, produce new elementary particles, or generate secondary beams, such as neutron beams.452
