Description

The magnetic coupling between nearby accelerator rings can introduce unwanted perturbations to beam dynamics, representing a potential concern for future colliders such as the High-Luminosity Large Hadron Collider, or multi-ring facilities such as the Future Circular Collider or the Muon Collider complex. To explore and benchmark this effect, dedicated tests were performed to study the electromagnetic interplay between the SPS and the LHC. Controlled excitations in the SPS were applied while monitoring the response of the beams in the LHC using high-precision instrumentation. Clear signatures of coupling were observed, providing valuable input for the validation of simulation models and for improving the understanding of magnetic field propagation between accelerator infrastructures. In this paper, the results of these measurements are presented and discussed.
