Numerical Studies of Designs of Clearing Electrodes for Ion Clearing in an ERL — Eden Tafa Tulu1, •Gisela Pöplau1, Atoosa Meseck2, and Ursula van Rienen1 — 1Universität Rostock — 2HZB, Berlin
Energy Recovery Linacs (ERLs) are the most promising candidates for next-generation light sources now worldwide under active development. An optimal performance of these machines requires the preservation of the high beam brightness generated in the injector. For this, the impact of the ionized residual gas on the beam has to be avoided as it causes instabilities and emittance growth.
Typical measures to reduce the effect of ion clouds are clearing electrodes. In this paper we present simulation studies for several designs of clearing electrodes that are in use at the Metrology Light Source (MLS) and under discussion for ion clearing in the Berlin Energy Recovery Linac Project - BERLinPro. The software tools we applied are CST Particle Studio and our in-house code MOEVE PIC Tracking.
