Postdoc in “Space Radiation Research and Ion Beam Therapy” (m/f)

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 ensure 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.

The working group Space Radiation Physics (subgroup of Biophysics) deals with the mitigation of radiation risks for astronauts being exposed to the spectrum of Galactic Cosmic Rays (GCR) and Solar Particle Events (SPE). One goal is to find novel shielding concepts and materials which are most suitable for their use in space application, regarding an optimal trade-off between safety, cost and weight. Therefore, measurements with high energy beams (GeV/u) and different detector systems are conducted in order to measure the shielding properties, especially the characteristics of the radiation field after the target.

The working group Medical Physics - in close cooperation with the Space Radiation group - is developing and commissioning a new dose delivery system for research in ion beam therapy. The new control system should provide advanced functionality (like treatment of moving tumours) and a faster scanning speed than the existing system, which was used for over 20 years for the GSI therapy pilot project. The goal is a next-generation beam application system that will be later used by clinical cooperation partners like the CNAO foundation in Pavia.

The GSI biophysics group is looking for a

Postdoc in
“Space Radiation Research and Ion Beam Therapy” (m/f)
Posting ID: 1580-18.92


Job Desription:

The postdoc should work in the field of space radiation research but also in ion-beam therapy. The planned tasks comprise:

  • Planning, conducting and analysing measurements for the shielding properties of new materials for high energy ion beams. Usage of diverse detector systems as scintillators (e.g. deltaE-E telescope), ionisation chambers, neutron detectors and corresponding data acquisition systems (VME, mTCA).
  • Usage of the Monte Carlo programs like GEANT4 or FLUKA for simulation of experimental setups and benchmarking of experiments.
  • Support for the commissioning of the raster scanning system. Preparing and conducting beam times and tests with the Medical Physics group. The focus lies on the development of new algorithms enabling intelligent processing of data from the position sensitive beam monitors in the raster scanning nozzle, aiming for a much faster scanning and a more precise feedback loop for the beam positioning correction.

Your Qualification:

  • PhD degree in Physics
  • Experience in the field of ion beam therapy or proton therapy
  • Experience with detectors for ion beam detection (measurement of dose, fragmentation cross sections, neutrons, attenuation length, characterization of mixed particle fields)
  • Strong programming skills (e.g. C/C++)
  • Strong Experience in modelling and simulation of radiation Transport

Our offer:

  • Working in an innovative, interdisciplinary and excellently equipped research group that is world leading in several fields of Research
  • Broad range of research Topics
  • Applied research in close connection with clinics


The position is limited for 2 years. Salary is equivalent to that for public employees as specified in the collective agreement for public employees (TVöD Bund).

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.
