The proton complex is the first piece in the Muon Collider, it comprises a high power acceleration section, a compressor and a target delivery system. For the International Muon Collider Collaboration (IMCC) we are investigating two possibilities: a 5 GeV (2 MW) and a 10 GeV (4 MW) final energies. In this work we present the updated design for the proton complex, including chopping schemes for...

Space charge effects are the main performance limitation for the beam brightness in the CERN Proton Synchrotron Booster (PSB). Operating at higher vertical tunes, near or above the vertical half-integer resonance 2Qy=9, offers more space in the tune diagram to accommodate the large space charge tune spread, potentially allowing for brighter beams. In this context, an experimental campaign was...
The China Spallation Neutron Source (CSNS) utilizes ceramic vacuum chambers in the high-dynamic-field regions of the Rapid Cycling Synchrotron (RCS) to preserve the vacuum environment of beam. Previous theoretical studies suggested that the impedance of this structure could be neglected concerning its impact on the beam. Recent measurements, however, have detected low-frequency resonant...
