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 is looking for a highly motivated and talented PhD Student to measure the spectral content of coherent radiation emitted by relativistic electron beams. These measurements, in combination with state-of-the-art numerical modeling, will allow us to understand the fundamental physics in dense clouds of charged particles, including the pairwise Coulomb interactions.

PhD Student for Experiments with Dense Coulomb Clouds

Your tasks

  • Set up a spectrometer to measure coherent radiation emitted by electron beams 
  • Measure the dependence of the spectrum on the accelerator set-up 
  • Use this experimental data, in conjunction with numerical models, to understand the interactions in dense coulomb clouds 
  • Collaborate with a multidisciplinary team of researchers 
  • Present the results at conferences and workshops, and prepare manuscripts for peer-reviewed publications

Your profile

  • Master’s degree in physics or engineering 
  • Strong experimental skills 
  • Knowledge of accelerator physics is an additional benefit 
  • Excellent analytical and problem-solving skills 
  • Ability to work independently and collaboratively in a team environment 
  • Strong communication and writing skills

We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure. 
ETH Zurich will be the PhD-granting university.
