Exploring the potential of resonance islands and bent crystals for a slow extraction from circular hadron accelerators / Veres, D.E. (CERN) ; Giovannozzi, M. (CERN) ; Franchetti, G. (Darmstadt, GSI)
New developments in accelerator physics have broadened the set of available techniques for manipulating charged-particle beams. Adiabatic trapping and transport of beam in resonance islands has been studied and successfully implemented at the CERN Proton Synchrotron to perform multiturn extraction. [...]

Harmonic analysis of nonstationary signals with application to LHC beam measurements / Russo, G. (CERN ; Frankfurt U.) ; Franchetti, G. (Darmstadt, GSI) ; Giovannozzi, M. (CERN) ; Maclean, E.H. (CERN)
Harmonic analysis has provided powerful tools to accurately determine the tune from turn-by-turn data originating from numerical simulations or beam measurements in circular accelerators and storage rings. Methods that have been developed since the 1990s are suitable for stationary signals, i.e., time series whose properties do not vary with time and are represented by stationary signals. [...]

Measurements and simulations of the e-cooling performance in ELENA / Kruyt, Peter (CERN) ; Gamba, Davide (CERN) ; Franchetti, Giuliano (Darmstadt, GSI ; CERN ; Frankfurt U.)
Understanding and optimizing the electron cooling performance is essential to ensure high-brightness antiproton beams at the Extra Low Energy Antiproton (ELENA) ring at CERN. This paper presents measurements and simulations of the electron cooling performance in ELENA. [...]

Observation of fixed lines induced by a nonlinear resonance in the CERN Super Proton Synchrotron / Bartosik, H (CERN) ; Franchetti, G (Darmstadt, GSI ; Frankfurt U. ; Helmholtz Res. Acad. Hesse for FAIR) ; Schmidt, F (CERN)
The motion of systems with linear restoring forces and recurring nonlinear perturbations is of central importance in physics. When a system’s natural oscillation frequencies and the frequency of the nonlinear restoring forces satisfy certain algebraic relations, the dynamics become resonant. [...]
