Beam-Beam Simulations for Double-Gaussian Beams [PDF]
Proceedings of the 2005 Particle Accelerator Conference, 2006 Electron cooling together with intra-beam scattering results in a transverse distribution that can best be described by a sum of two gaussians, one for the high-density core and one for the tails of the distribution [1]. Simulation studies are being performed to understand the beam-beam interaction of these double-gaussian beams.

Beam-beam effects in RHIC [PDF]
, 2012 In this article we review the beam-beam effects in the polarized proton runs in the Relativistic Heavy Ion Collider (RHIC). The operational observations, limitations, and the next luminosity goal are presented and discussed. With an upgraded polarized proton source, the proton bunch intensity will be increased from 1.7 × 10 up to 3.0 × 10.

A unified approach for beam-to-beam contact [PDF]
Computer Methods in Applied Mechanics and Engineering, 2017 Existing beam contact formulations can be categorized in point contact models that consider a discrete contact force at the closest point of the beams, and line contact models that assume distributed contact forces. In this work, it will be shown that line contact formulations provide accurate and robust mechanical models in the range of small contact ...
