PhD student for Computational Methods in Dense Coulomb Clouds

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 Accelerator Simulation and Advanced Modeling Group is looking for a highly motivated and talented PhD Student to investigate the fundamental physics of Dense Coulomb Clouds (CCs). This project combines state-of-the-art numerical modelling with experimental validation at leading facilities like Argonne National Laboratory, SwissFEL and EuPRAXIA.
