Description
Six-dimensional muon cooling is essential for reducing the beam emittance to the level required for a high-luminosity muon collider. To investigate possible collective effects in such high-brightness muon beams, a new space charge module has been implemented in G4beamline and recently improved for simulations of muon cooling channels. The module has been assessed through benchmark, convergence, and numerical-consistency studies and applied to a rectilinear 6D cooling channel. The study examines the influence of space charge on transverse and longitudinal emittance evolution, beam transmission, phase-space distributions, and overall cooling performance, providing a numerical basis for evaluating possible intensity limitations in muon cooling systems.
