Alexander Koschik (CERN) will give a talk on

"Simulation of Transverse Multi-Bunch Instabilities of Proton Beams in LHC"

Abstract:

The CERN Large Hadron Collider (LHC) is designed for highest luminosity and therefore requires operation with a large number of bunches and high intensities. Its performance could be limited by the electromagnetic interaction between the charged particle beam and its surroundings which cause collective instabilities.

The talk presents methods of simulating multi-bunch instabilities in circular accelerators and storage rings and focuses in particular on the resistive wall instability. A fast wake summation method, which is based on the convolution theorem and the discrete FFT, will be presented.
