The origin of energetic non-thermal particles in the Universe is an open question. Collisionless shocks [1-3], with their associated instabilities [4], can transfer energy to particles during their interaction with ambient plasma. Using high-power lasers coupled with strong magnetic fields, we can produce such shocks and instabilities in the laboratory and observe the energization of protons.
