Wakefield Study for a PCB-Based Arrival-Time Pickup for Electron Accelerators — •Bernhard Erich Jürgen Scheible^1,2, Marie Kristin Czwalinna³, Holger Schlarb³, Wolfgang Ackermann², Herbert De Gersem², and Andreas Penirschke¹ — ¹Technische Hochschule Mittelhessen, Wilhelm-Leuschner-Str. 13, 61169 Friedberg, Germany — ²Technische Universität Darmstadt, Karolinenplatz 5, 64289 Darmstadt, Germany — ³Deutsches Elektronen-Synchrotron DESY, Notkestr. 85, 22607 Hamburg, Germany

Many scientific applications utilize large-scale electron accelerators, e.g., for imaging in free-electron laser facilities such as the European XFEL or FLASH. Precise timing information is necessary for stable operation or to control and evaluate experiments. With growing demands on the accuracy of beam diagnostics especially with smaller bunch-charges, it is unavoidable that monitoring concepts significantly affect the beam. To prevent this interaction from becoming intolerable, it is necessary to quantify and compare it with existing state-of-the-art structures. In this contribution the wake loss factor of a pickup structure based on a printed circuit board is determined in electromagnetic simulations and compared to the pickups of the European XFEL.
