Simulation of electron beam - ion interactions — •Aleksandar Markovik and Ursula van Rienen — Universität Rostock, Institut für Allgemeine Elektrotechnik, Albert-Einstein-Str. 2, D-18059 Rostock

Parasitic ions generated by synchrotron radiation and collisions of the electron beam and the rest gas in the vacuum chamber of a particle accelerators could harm the quality of the beam. Therefore numerical simulations of their behavior in the field of the electron beam and/or beam guiding magnets are indispensable to achieve an understanding of the phenomena and to possibly model their influence on the beam. Here we present results of a tracking simulation of the ion distribution over a relatively long period of time. During that time the ions interact up to thousand times with the passing bunches.
