Particle accelerators produce and speed up beams of charged particles, similar to electrons, protons, and ions which could be linear or round, of various sizes. In high-intensity round particle accelerators, resonances could be an inconvenience, inflicting particles to fly off their course and leading to beam loss.
Scientists on the Tremendous Proton Synchrotron (SPS), in collaboration with scientists at GSI in Darmstadt, have been in a position to experimentally show the existence of a specific resonance construction.
