Particle physics has arrived at an important moment of its history. The discovery of the Higgs
boson, with a mass of 125 GeV, completes the matrix of particles and interactions that has …

In this paper, results concerning the phenomenon of adiabatic trapping into resonance for a
class of quasi-integrable maps and Hamiltonians with a time-dependent exciter are …

This Letter reports the first observations of an anomalous hollow electron beam in the Duke
storage ring. Created by exciting the single-bunch beam in a lattice with a negative …

Trapping phenomena involving nonlinear resonances have been considered in the past in
the framework of adiabatic theory. Several results are known for continuous-time dynamical …

Controlling nonlinear effects in the transverse dynamics of charged particle beams in
circular accelerators opens new possibilities for controlling some of the beam properties …

Crossing the transition energy is always a delicate process, representing a potential source
of strong perturbations of the dynamics of charged particle beams in a hadron circular …

In many problems of classical mechanics and theoretical physics dynamics can be
described as a slow evolution of periodic or quasi-periodic processes. Adiabatic invariants …

The multiturn extraction from a circular particle accelerator is performed by trapping the
beam inside stable islands of the horizontal phase space. In general, by crossing a …
