Cleaning the beam halo using nonlinear AC magnets
F. Capoani, A. Bazzani, M. Giovannozzi
Recently, nonlinear effects have been utilized to cool a special beam represented by an annular distribution in a 2D phase space. This outcome was accomplished using an AC dipole c…
Measurement of the nonlinear diffusion of the proton beam halo at the CERN LHC
C. E. Montanari, R. B. Appleby, A. Bazzani +5
In circular particle accelerators, storage rings, or colliders, mitigating beam losses is critical to ensuring optimal performance, particularly for rings that include superconduct…
Exploring the Potential of Resonance Islands and Bent Crystals for a Novel Slow Extraction from Circular Hadron Accelerators
D. E. Veres, G. Franchetti, M. Giovannozzi
New developments in accelerator physics have broadened the set of available techniques for manipulating charged-particle beams. Adiabatic trapping and transport of beam in resonanc…
Analysis of double-resonance crossing in adiabatic trapping phenomena for quasi-integrable area-preserving maps with time-dependent exciters
A. Bazzani, F. Capoani, M. Giovannozzi
In this paper, we analyze the adiabatic crossing of a resonance for Hamiltonian systems when a double-resonance condition is satisfied by the linear frequency at an elliptic fixed…
