Head-tail instability and Landau damping in bunches with space charge
Physical Review Special Topics. Accelerators and Beams, 2010 Head-tail modes in bunches with space charge are studied using particle tracking simulations. The eigenfrequencies and eigenfunctions of transverse coherent oscillations in a Gaussian bunch are determined and compared with theories. A model for an airbag

Simulation study of the space charge limit in heavy-ion synchrotrons
Physical Review Accelerators and Beams, 2022 The SIS100 synchrotron as a part of the new Facility for Antiproton and Ion Research (FAIR) accelerator facility at GSI should be operated at the “space charge limit” for light- and heavy-ion beams.

Space Charge Modelling in Solid Dielectrics under High Electric Field Based on Double Charge Injection Model [PDF]
, 2005 Present study aims to develop a clear insight on factors that influence space charge dynamics in solid dielectrics through a numerical simulation. The model used for the simulation is proposed by Alison and Hill [1] which describes charge dynamics as a ...

Transverse stability with nonlinear space charge
Physical Review Special Topics. Accelerators and Beams, 2001 Transverse stability with nonlinear space charge is studied within the context of coasting beams. For bare tune spreads originating from chromaticity or frequency slip, the space charge tune spread has a fairly small effect and the incoherent space ...

, 2014 The space charge forces are those generated directly by the charge distribution, with the inclusion of the image charges and currents due to the interaction of the beam with a perfectly conducting smooth pipe. Space charge forces are responsible for several unwanted phenomena related to beam dynamics, such as energy loss, shift of the synchronous phase

Transverse mode-coupling instability and space charge
Physical Review Accelerators and Beams, 2018 Transverse mode-coupling instability (TMCI) is known to limit bunch intensity. Since space charge (SC) changes coherent spectra, it affects the TMCI threshold.
