The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2300 people. The Electron Beam Instrumentation Group develops instruments that measure the properties of electron beams and engages in advanced accelerator research. Recently, we started developing and applying multiphysics and particle-in-cell (PIC) simulation tools to optimize the design and performance of plasma-based particle acceleration and beam manipulation systems. In this context, we are looking for a

You will contribute to the development and optimization of plasma-based beam manipulation devices, with a focus on Active Plasma Lenses (APLs). The work will be primarily computational in nature, with two main simulation directions available depending on your background and interests. The first direction involves multiphysics simulations, including CFD studies to optimize neutral gas distribution within plasma discharge capillaries, acoustic analyses aimed at achieving greater control over the transverse gas density profile, and potentially simulations of plasma arc formation. The second direction involves the development of a PIC-based (Particle In Cell) simulation framework — using existing codes such as FBPIC, Smilei, or WarpX — to study and minimize beam-plasma wakefield effects during beam propagation through APL devices, including syste...
