Charged particles can be accelerated to high velocities by electromagnetic fields. They are then able to travel through matter (termed an absorber), interacting with it, losing energy, and causing various effects important in many applications. In traveling through matter, charged particles interact with nuclei, producing nuclear reactions and elastic and inelastic collisions, and also collide with the electrons (electronic collisions) and with entire atoms of the absorber (atomic collisions).
