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. 

We are seeking a highly motivated postdoctoral fellow to join the Advanced Muon Spectroscopy (AMS) project at the Laboratory for Muon Spin Spectroscopy (LMU). The project is dedicated to developing a novel method for muon spin spectroscopy using monolithic Si-pixel detectors. 

This innovative approach aims to increase data collection rates (40k ⇒ >400k muons/second), enable measurements on smaller samples (16mm2 ⇒ 1mm2), and achieve lateral resolution on the millimeter scale. This is an excellent opportunity to contribute to cutting-edge instrumentation and methodology for muon spectroscopy, while working in a collaborative, international research environment.
