Description
In the current design of the International Muon Collider Collaboration proton complex, a compressor ring rotates the proton beam in longitudinal phase space to produce the short pulses required for muon production. Previous simulation studies of this compressor have relied on 2.5D Particle-in-Cell (PIC) space charge in Xsuite, which employs a static mesh (i.e., it does not adapt to an evolving beam size). To validate these results, an adaptive mesh has been implemented and 3D space charge has been tested, followed by a convergence study and a tune sweep. A resonance phenomenon originally believed to be space-charge driven has been investigated, and the selection of an optimal working point has been further explored. The results show that both the adaptive mesh and 3D space charge introduce significant differences relative to the previous configuration, although compression to 2 ns should still be feasible provided the severity of micro-bunching is not significant. This work presents an overview of these studies and discusses their implications for optimization of the compressor.
