Question

In 3–4 sentences, describe how a particle accelerator works and give an example of the applications of the discoveries made with them.(4 points)

Answer 1

Particle accelerators use electric fields to speed up charged particles and magnetic fields to steer and focus their beams, bringing them to very high energies. Those beams are smashed into targets or each other so detectors can record the resulting particles and interactions, revealing the structure and forces of matter. The data are analyzed to test theories and discover new particles (for example, the Higgs boson). Practical applications of such discoveries and technologies include PET medical imaging and particle-beam cancer therapies.
