An Object-Oriented Parallel Particle-in-Cell Code for Beam Dynamics Simulation in Linear Accelerators
TL;DR: An object-oriented three-dimensional parallel particle-in-cell (PIC) code for simulation of beam dynamics in linear accelerators (linacs) using split-operator methods to integrate single-particle magnetic optics techniques with parallel PIC techniques is presented.

A parallel particle-in-cell model for beam-beam interaction in high energy ring colliders
TL;DR: In this article, a self-consistent simulation model of colliding beams in high energy ring colliders is presented, which is based on a particle-in-cell method, using a new developed shifted effective Green function algorithm for the efficient calculation of the beam beam interaction with arbitrary separation and large aspect ratio.
