Analytical method for determining at equilibrium the envelope and emittance of initially mismatched beams
(2009) [Artículo de periódico]This work presents a fully analytic way of determining relevant equilibrium quantities of a high-intensity charged particle beam submitted to magnetic focusing while inside a linear channel. Through the current approach, ... -
An analytical model to determine equilibrium quantities of azimuthally symmetric and mismatched charged particle beams under linear focusing
(2008) [Artículo de periódico]The model developed here analytically allows to obtain equilibrium quantities of interest from high-intensity charged particle beams such as the emittance, beam envelope, and the number of beam halo particles. The results ... -
Nonlinear dynamics of inhomogeneous mismatched charged particle beams
(2012) [Artículo de periódico]This work analyzes the transversal dynamics of an inhomogeneous and mismatched charged particle beam. The beam is azimuthally symmetric, initially cold, and evolves in a linear channel permeated by an external constant ... -
Nonlinear dynamics of relativistic charged particle beams
(2011) [Artículo de periódico]The idea behind this work is to analyze the transversal dynamics of a relativistic charged particle beam. The beam is azimuthally symmetric, focused by a constant magnetic field and supposed to be initially cold. While ... -
On the counterpropagation of waves
(2019) [Artículo de periódico]This work analyses the counterpropagation of transversal plane waves in a linear, homogeneous, nondispersive, and isotropic medium. Although this is a traditional subject in disciplines associated with wave phenomena, a ... -
Relaxation of intense inhomogeneous charged beams
(2009) [Artículo de periódico]This work analyzes the dynamics of inhomogeneous, magnetically focused high intensity beams of charged particles. Initial inhomogeneities lead to density waves propagating transversely in the beam core, and the presence ... -
Simplified self-consistent model for emittance growth in charged beams with mismatched envelopes
(2007) [Artículo de periódico]This paper analyzes the envelope dynamics of magnetically focused, high-intensity charged particle beams. As known, mismatched envelopes decay into equilibrium with simultaneous emittance growth. To describe the emittance ... -
The controlling role of envelope mismatches in intense inhomogeneous charged beams
(2010) [Artículo de periódico]Inhomogeneous cold beams undergo wave breaking as they move along the axis of a magnetic focusing system. All the remaining control parameters fixed, the earliest wave breaking is a sensitive function of the inhomogeneity ... -
Transversal dynamics of relativistic charged particle beams
(2014) [Artículo de periódico]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, ...
