Future ultralow emittance rings for e-/e+ colliders require extremely high beam brightness
and can thus be limited by collective effects. In this paper, the interplay of effects such as …

Understanding the 3D collective long-term response of beams exposed to resonances is of
theoretical interest and essential for advancing high intensity synchrotrons. This study of a …

After the successful implementation of the LHC Injectors Upgrade (LIU) project, studies were
conducted in the CERN Proton Synchrotron Booster (PSB) in order to assess the intensity …

Space charge is typically one of the performance limitations for the operation of high
intensity and high brightness beams in circular accelerators. In the Proton Synchrotron (PS) …

The ion injectors of the CERN accelerator chain, in particular the Super Proton Synchrotron
(SPS) and the Low Energy Ion Ring (LEIR), operate in a strong Space Charge (SC) and Intra …

Detrimental beam dynamics effects limit the performance of high-intensity rapid cycling
synchrotrons (RCSs) such as the 8 GeV proton Fermilab Booster. Here we report the results …

The motion of systems with linear restoring forces and recurring nonlinear perturbations is of
central importance in physics. When a system's natural oscillation frequencies and the …
