Chaos and emittance growth due to nonlinear interactions in a circular accelerator

Physical Review Special Topics. Accelerators and Beams, 2007
Incoherent emittance growth caused by a strong nonlinear interaction between beam and electron cloud is discussed. This emittance growth arises from nonlinear diffusion related to chaos and resonances, and strongly depends on the number of degrees of ...

Halo Formation due to Beam-Beam Interaction [PDF]

AIP Conference Proceedings, 2003
In colliding‐beam storage rings transverse and longitudinal beam halo is generated, or depleted, by the effect of head‐on and long‐range beam‐beam collisions. Measurements from several past and present lepton or hadron colliders are compared with simulations and analytical models, highlighting a few halo‐specific techniques.

Limitation of the Gaussian approximation in beam-beam simulations

Physical Review Special Topics. Accelerators and Beams, 2000
The soft-Gaussian approximation is often employed in computer simulations of strong-strong beam-beam interactions in storage rings. Its defect on the coherent oscillation frequency is pointed out and a possible remedy using Hermitian polynominals is ...

Beam-Beam Interaction with a Crossing Angle [PDF]

, 2003
A fairly accurate mapping for the beam-beam interaction with a crossing angle is proposed. Some simple results of the weak-strong tracking are shown: the beam-beam interaction becomes more serious when the crossing angle increases until the normalized angle {Phi} becomes about a half. Above this, it becomes less serious.

First experimental evidence of a beam-beam long-range compensation using wires in the Large Hadron Collider

Physical Review Accelerators and Beams
In high intensity and high energy colliders, such as the CERN Large Hadron Collider (LHC) and its future high-luminosity upgrade, interactions between the two beams around the different interaction points impose machine performance limitations.

Long-range attraction of an ultrarelativistic electron beam by a column of neutral plasma

New Journal of Physics, 2016
We report on the experimental observation of the attraction of a beam of ultrarelativistic electrons towards a column of neutral plasma. In experiments performed at the FACET test facility at SLAC we observe that an electron beam moving parallel to a ...
