Abstract It is well known that the combination of Space charge and lattice imperfections can put the beam stability at stake when it has to survive for a large number of turns. In such cases, particles may exhibit chaotic motion leading to particle losses and beam blow-up. Therefore, tools that predict at which amplitudes the particle motion becomes chaotic are always welcome. There are already tools of such use, like Frequency Map Analysis. In this study, the newly developed tool, Chaos Map Analysis, will be reviewed and compared with the former. Instead of determining the chaotic behavior of particles with tune diffusion, the Chaos Map Analysis method takes advantage of the phase-space-difference evolution between two particles presenting visual results onto a 6D amplitude grid. The results of this study show that the Chaos Map Analysis method is in great agreement with the Frequency Map Analysis.
