Electron beam relaxation in inhomogeneous plasmas [PDF]

open access: yesAnnales Geophysicae, 2013
In this work, we studied the effects of background plasma density fluctuations on the relaxation of electron beams. For the study, we assumed that the level of fluctuations was so high that the majority of Langmuir waves generated as a result of beam ...

Incoherent pair generation in a beam-beam interaction simulation [PDF]

open access: yesPhysical Review Special Topics - Accelerators and Beams, 2006
This paper deals with two topics: the generation of incoherent pairs in two beam-beam simulation programs, GUINEA-PIG and CAIN, and the influence of the International Linear Collider (ILC) beam parameter choices on the background in the micro–vertex detector (VD) induced by direct hits. One of the processes involved in incoherent pair creation (IPC) is

Electron beam profile imaging in the presence of coherent optical radiation effects

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2012
High-brightness electron beams with low energy spread at existing and future x-ray free-electron lasers are affected by various collective beam self-interactions and microbunching instabilities. The corresponding coherent optical radiation effects, e.g.,

Observations of the beam-beam interaction [PDF]

open access: yes, 2007
The observed complexity of the beam-beam interaction is the subject of this paper. The varied observations obtained from many storage rings happen to be sufficiently similar that a prescription can be formulated to describe the behavior of the luminosity as a function of beam current including the peak value.

Magnetic pinching of relativistic particle beams: a new approach to strong-field QED physics

open access: yesNew Journal of Physics, 2023
Quantum electrodynamics (QED) is a foundation of modern physics, yet access to the strong-field QED regime in the laboratory remains a formidable challenge.

Beam-beam interaction in muon colliders

open access: yesNuclear Physics B - Proceedings Supplements, 1996
Inspired by the hybrid nature of muon colliders, we investigate the classical and quantum effects induced by the μ + μ − beam-beam interaction. We show that although the tendency of emittance dilution appears to be substantial in a single pass, it nevertheless quickly saturates.

Measurements of the beam-beam interaction at PEP-II [PDF]

open access: yesPACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2002
The beam-beam interaction is one of the performance limitations at PEP-II. The peak luminosity in PEP-II has reached 3.4 /spl times/ 10/sup 33//cm/sup 2//s with 693 bunches with a positron current of 1.6 A and an electron current of 0.84 A. The beam-beam tune shift limits have exceeded 0.06 horizontally and 0.03 vertically.

Halo formation due to beam-beam interactions of beams optically mismatched at injection

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2004
In this paper, we report on the halo formation and emittance growth driven by a parametric resonance during beam-beam collisions with optically mismatched injection.

Review of linear collider beam-beam interaction [PDF]

open access: yesAIP Conference Proceedings, 1989
Three major effects from the interaction of e+e− beams — disruption, beamstrahlung, and electron‐positron pair creation — are reviewed. For the disruption effects we discuss the luminosity enhancement factor, the maximum and rms disruption angles, and the kink instability. All the results are obtained from computer simulations.
