Self-Focusing Dynamics of Coupled Optical Beams [PDF]
, 2006 We theoretically and experimentally investigate the mutual collapse dynamics of two spatially separated optical beams in a Kerr medium. Depending on the initial power, beam separation, and the relative phase, we observe repulsion or attraction, which in ...

, 2007 This paper gives an overview of the transverse dynamics in particle acceler- ators with – following the emphasis of the school – special focus (hic) on transfer lines and application for beam injection and extraction. We will re- strict ourselves to a bare an introduction to the basic concepts that are needed to understand the boundary conditions to be

A study of coherent and incoherent resonances in high intensity beams using a linear Paul trap
New Journal of Physics, 2019 In this paper we present the first quantitative measurement of the change in frequency (tune) with intensity of four transverse resonances in a high intensity Gaussian beam.

Measurement of dynamic beam-beam effects [PDF]
Physical Review Special Topics - Accelerators and Beams, 2005 A series of measurements were carried out to investigate the dynamic beam-beam effects at KEKB. The beam-beam kick and the coherent beam-beam tune shift were measured by comparing the beam parameters between a colliding bunch and a noncolliding one. We found that collisions occur with a horizontal orbit offset to obtain the maximum luminosity, and that

Lossless crossing of a resonance stopband during tune modulation by synchrotron oscillations
New Journal of Physics, 2017 Modern high performance circular accelerators require sophisticated corrections of nonlinear lattices. The beam betatron tune footprint may cross many resonances, reducing dynamic aperture and causing particle loss.

Investigation of the transverse beam dynamics in the thermal wave model with a functional method [PDF]
, 2006 We investigated the transverse beam dynamics in a thermal wave model by using a functional method. It can describe the beam optical elements separately with a kernel for a component.

Dynamic modulation of Poincaré beams [PDF]
Scientific Reports, 2017 AbstractGeneration of complex Poincaré beams is enabled by amplitude and phase modulation accompanied by simultaneous spatially polarization structuring. A holographic system to tailor complex light fields and optical angular momentum structures forecasts promising applications in quantum communication and optical trapping.

On the dynamics of Airy beams in nonlinear media with nonlinear losses
, 2015 We investigate on the nonlinear dynamics of Airy beams in a regime where nonlinear losses due to multi-photon absorption are significant. We identify the nonlinear Airy beam (NAB) that preserves the amplitude of the inward H\"ankel component as an ...

Self modulated dynamics of a relativistic charged particle beam in plasma wake field excitation
, 2015 Self modulated dynamics of a relativistic charged particle beam is reviewed within the context of the theory of plasma wake field excitation. The self-consistent description of the beam dynamics is provided by coupling the Vlasov equation with a Poisson ...
