In this paper, simulation codes for Beam Delivery Systems in linear colliders are discussed. Several tracking codes are available for particle tracking. They do not normally include precise calculation of the beam-beam effect, with accounting for pinch, hour-glass, pair production. They provide instead the particle distributions at the interaction point, after tracking through the different com...

Realistic calculation of NLC luminosity has been performed using particle tracking in DI-MAD and beam-beam simulations in GUINEA-PIG code for various values of beam emit-tance, energy and beta functions at the Interaction Point (IP). Results of the simulations are compared with analytic luminosity calculations. The optimum range of IP beta functions for high luminosity was identified. Abstract ...

The importance of nonlinear beam dynamics effects in synchrotron light sources is caused by strong demands on beam quality to obtain long lifetime, small emittance and stability. In this paper, the non-linear particle trajectory equation modifications are given, which simplify the single particle tracking simulation in storage ring using the Matlab environment [1]. The radiation damping times i...

In this note we present results of beam tracking in the NLC extraction line for the NLC option with high luminosity beam parameters (Option H). Particle losses for 0.5 TeV and 1 TeV cms energy beams have been computed and examined as a function of beam offset at the interaction point (IP). Updated tracking results for the NLC Option A are presented as well. Beam Losses in the NLC Extraction Lin...

The study of beam transport is of central importance to the design and performance assessment of modern particle accelerators. In this paper, we benchmark two contemporary codes, DIMAD and BDSIM, the latter being a relatively new tracking code built within the framework of GEANT4. We consider both the 20 mrad and 2 mrad extraction lines of the 500 GeV International Linear Collider (ILC) and we ...

We present an update on the development of the new code for long-term simulation of beam-beam effects in particle colliders. The underlying physical model relies on a matrix-based arbitrary-order particle tracking (including a symplectic option) for beam transport and the generalized Bassetti-Erskine approximation for beam-beam interaction. The computations are accelerated through a parallel im...

SimTrack is a compact c++ library of 6-d symplectic element-by-element particle tracking in accelerators originally designed for head-on beam-beam compensation simulation studies in the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. It provides a 6-d symplectic orbit tracking with the 4th order symplectic integration for magnet elements and the 6-d symplectic synchro-...
