Abstract
The idea behind this work is to analyse the transversal dynamics of a relativistic charged particle beam. The beam is azimuthally symmetric, focused by a constant magnetic field and supposed initially cold. While mismatched, nonrelativistic and homogeneous beams oscillate with an invariant cold density profile, it is shown that relativistic homogeneous beams progressively heat and lose an important amount of constituents during its magnetic confinement. This heating process starts with phase-space wave breaking, a mechanism observed before in initially inhomogeneous beams. The results have been obtained with full self-consistent N -particle beam numerical simulations.
Highlights
Beams composed by charged particles usually evolve to its equilibrium state with the ejection of some representative amount of its constituents as propagate inside the magnetic focusing channel
While the first population is recognized as the beam halo, the second one is denoted as beam core [1][2][3][4]
For initially cold, non-homogeneous but envelope matched beams, it has been found that the forerunner mechanism by which particles are ejected from the core is through phase-space wave
Summary
Beams composed by charged particles usually evolve to its equilibrium state with the ejection of some representative amount of its constituents as propagate inside the magnetic focusing channel. For initially cold, non-homogeneous but envelope matched beams, it has been found that the forerunner mechanism by which particles are ejected from the core is through phase-space wave- Suppose an initially homogeneous beam of charged particles evolving inside a linear channel.
