Phd student in “Radiation Physics” (all genders)

GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt operates one of the leading particle accelerators for science. In the next few years, the new FAIR (Facility for Antiproton and Ion Research) one of the world's largest research projects, will be built in international cooperation. GSI and FAIR offer the opportunity to work together in this international environment with a team of employees committed to ensuring each day to conduct world-class science.

The Biophysics department is an interdisciplinary collaboration of biologists, physicists, chemists, biochemists and technicians. The multidisciplinary research in our group covers a wide range of topics from radiobiology, radiation physics and space research to radiation therapy.


One working field of the group Radiation Physics (subgroup of Biophysics) deals with FLASH irradiation treatment, a now modality for radiation therapy.


The GSI Biophysics department is looking as soon as possible for a

in part-time (65%).


Your Tasks:

  • planning, simulation (Monte Carlo) and setting up experiments for beam application at Ultra High Dose Rates (UHDR) also called ‘FLASH’ beam application.

Experiments could be performed at GSI with high intensity Carbon beams or eventually at external proton therapy facilities.


Your Qualification:

  • Master degree in Physics
  • Knowledge in Monte Carlo Simulations
  • Experience and knowledge with particle beam application for therapy
  • Programming skills (e.g. C/C++, Python)


We offer you a position in an innovative, interdisciplinary and excellently equipped research group that is world leading in biophysics and radiobiology for charged particle beams, excellent technical infrastructure including an outstanding high-energy accelerator system. The position is initially offered for 3 years.


Salary and benefits are based on the collective agreement for public employees (TVöD Bund) effective at GSI.


GSI supports the vocational development of women. Therefore, women are especially encouraged to apply for the position.


Handicapped persons will be preferentially considered when equally qualified.
