Your tasks The muon electric dipole moment experiment, muEDM at PSI, is searching for a signal of CP-violation beyond the Standard-Model. Together with the international collaboration you will: * Take first data on storage, spin precession, and frozen-spin state of muons * Participate in data analysis and work on dedicated aspects related to the magnetic field of the storage trap * Further characterizing the magnetic field of the storage trap using dedicated sensors and particle detectors * Contribute to a better understanding of systematic effects and help to improve experimental sensitivity Your profile * Master-s degree in physics with strong interest in low energy particle physics * Knowledge of computational numerical methods, i.e. Monte Carlo simulations, Python for data analysis, finite element methods, etc. * Practical experience in experimental techniques is appreciated (e.g. electronics, detectors, DAQ) * Ability to work independently * Proficient level of English as working language in spoken and written form is mandatory * Knowledge of German or willingness to quickly learn German is a plus 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.
