Abstract :
We investigate the nonlinear coupling between breathing and quadrupole-like oscillations in the dynamics of intense beams propagating in a uniform magnetic focusing field. It is shown that finite amplitude breathing oscillations of an initially round beam may destabilize quadrupole-like oscillations, heavily affecting stability and the shape of the beam. This is a potential mechanics for beam particle loss in such systems.
