FREQUENCY MAP ANALYSIS OF BEAM HALO FORMATION IN A HIGH INTENSITY PROTON LINAC

In this paper we describe the progresses achieved in the application of modern Hamiltonian dynamics tools, like frequency map analysis, to the problem of beam halo formation in a high intensity proton linac. In particular we discuss the extension of the approach introduced for a continuous beam in a FODO channel to a realistic linac, considering the problems connected with longitudinal dynamics and acceleration.
