Resonances are a familiar concept, whether in music or on a playground. However, in high-intensity circular particle accelerators, resonances can cause particles to veer off course, resulting in beam loss. Understanding how resonances and non-linear phenomena affect particle beams is a complex task.
The latest results, published in Nature Physics, will help improve beam quality for various facilities, including the LHC injectors at CERN and the SIS18/SIS100 facility at GSI. “With these resonances, particles don’t follow the desired path and get lost, causing beam degradation,” says Giuliano Franchetti, a scientist at GSI.
Scientists at GSI and CERN collaborated to understand the limitations of high-intensity accelerators. The effort involved developing theories and simulations to comprehend the effect of resonances on beam stability. The simulations revealed that resonance structures induced by coupling in two degrees of freedom are a major cause of beam degradation.
