The combined effect of space charge and nonlinear resonance on beam loss and emittance
was measured in a benchmarking experiment over a 1.2 s long flat bottom at 1.4 GeV kinetic …

Trapping of particles in nonlinear resonances in the presence of space charge and
synchrotron motion may be a source of beam halo generation and beam loss in high …

The influence of linear betatron coupling due to constant-in-time skew quadrupolar fields on
the transverse emittances is discussed using both a simplified model of a smooth circular …

We study halo emittance growth in anisotropic beams and show that the rms emittance
growth resulting from mismatch is highly anisotropic, depending on the tune ratio. We find …

In this paper we present a comprehensive analysis of the self-consistent, collective behavior
associated with the space-charge-driven (Montague) coupling resonance near 2 Q x-2 Q y …

Direct space charge forces can be simulated with the 6D beam dynamics code MADX using
a number of 4D BEAMBEAM elements with Gaussian transverse profile for charge density …

In this paper we present a method for measuring the nonlinear errors in a circular
accelerator by taking advantage of the feed-down effect of high order multipoles when the …

In high-intensity accelerators space-charge-induced emittance coupling, known as
Montague resonance, is known to occur for small tune split, where it can lead to emittance …

Long term storage of high intensity beams with small loss is required in the FAIR project at
GSI as well as for JPARC. In this paper we discuss that an important contribution to the loss …

Abstract Space charge has a destructive and hazardous impact on electronics, navigation
systems, and instrumentation onboard spacecraft, as well as the spacecraft itself. Therefore …
