PhD Candidate (m/f/d) in Experimental Physics – fixed term / Part time (50%)

The Helmholtz-Institute Mainz (HIM) is a joint institution of the Johannes Gutenberg-University Mainz (JGU) and the GSI Helmholtz Centre for Heavy Ion Research GmbH in Darmstadt. The Helmholtz-Institute Mainz combines the expertise of the Institute of Physics, Institute of Nuclear Physics, and the Institute of Nuclear Chemistry at the University Mainz with the GSI in Darmstadt to study the questions of structure, symmetry, and stability of matter and antimatter. HIM is located on the campus of the University Mainz and consists of 6 independent research divisions: Theory Floor, Electromagnetic Processes, Hadron Spectroscopy and Flavour, Symmetry of Matter and Antimatter, Superheavy Elements, Accelerator Physics and Integrated Detectors.


For the section SPECF at the Helmholtz-Institute Mainz we are looking for a


PhD Candidate (m/f/d) in Experimental Physics – fixed term

Part time (50%)

Posting-ID: 4314-19.139


The hypothesis that dark matter particles belong to a new, unexplored dark sector, that is communicating with the Standard Model through light dark mediator particles, is gaining interest. To explore this idea, the Mainz Energy-recovering Superconducting Accelerator (MESA) will be used for a search for light dark matter (DarkMESA).


Your responsibilities:

  • Work on the idea of using the MESA beam dump for searches for light dark matter.
  • Work on the design, prototype development and construction of the DarkMESA calorimeters and veto detectors.
  • Development of simulation and analysis codes for the detectors.
  • Cooperation with other light dark matter searches at MESA and other beam dump experiments at accelerators worldwide.
  • Guidance of Bachelor and Master students.


Your qualifications:

  • Master degree in physics with at least the German grade "good" (or equivalent).
  • Practical experience with particle detectors, read-out electronics, and/or data acquisition systems.
  • Proficiency in programming languages and experience with simulation and analysis tools commonly applied in nuclear and particle physics.
  • Excellent knowledge of spoken and written English is essential.


We offer an initial employment contract of 3 years. Salary is equivalent to that for public employees as specified in the collective agreement for public employees (TVÖD).

The Helmholtz Institute Mainz promotes the professional development of women and therefore expressly welcomes applications from women.

Handicapped persons will be preferentially considered when equally qualified.

Information about FAIR and GSI is available at www.gsi.de  and www.fair-center.eu.
