Research Scientist (PhD) (d/f/m) for Nuclear Physics Experiments

The FRS/SFRS group offers a Tenure Track position for a Research Scientist for Nuclear Physics Experiments

  • Closing soon
  • Closing date: 31 Jul 2020
  • Germany | GSI Helmholzzentrum fuer Schwerionenforschung GmbH
  • Date posted: 03 Jul 2020
  • Job type: Research facilities
  • Discipline: Accelerators, neutron & light sources 

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 in this international environment with a team of employees committed to ensuring each day to conduct world-class science. The FRS/SFRS group is one of the major partners for nuclear physics experiments at the GSI accelerator facility. The group operates and maintains the fragment separator FRS, a separator and spectrometer for heavy-ion and exotic nuclear beam experiments, it supports the development and preparation of the super-conducting fragment separator SFRS of the international accelerator facility FAIR. At both instruments, short-lived exotic nuclei are produced, separated and studied with modern detector systems. The FRS/SFRS group is integral part of large international scientific collaborations and performs experiments at the cutting edge of modern nuclear science.

The FRS/SFRS group offers a Tenure Track position for a Research Scientist (PhD) (d/f/m) for Nuclear Physics Experiments Posting-ID: 1230-20.37.
Position overview and responsibilities
The candidate will conduct research with high-intensity primary and secondary beams at the FRS and be integrated in collaborative activities of the NUSTAR and Super-FRS Experiment Collaboration. She/he will be responsible for the operation of the FRS for user experiments and maintenance of the scientific-technical infrastructure of the FRS, in particular its Standard Equipment for particle production, separation and identification. She/he will also be actively involved to provide the FRS as test bench for key components of the Super-FRS, such as ion-optical separation modes, target and material tests, detector development etc. The task specifically includes to simulate, prepare and implement the approved NUSTAR experiments, which use the FRS. She/he will also coordinate the operation with the experimentalists, the FRS/SFRS group and the accelerator operation group.

Main activities

  • Operation, maintenance and further development of the fragment separator for experiments, especially within the NUSTAR Collaboration, supervision of the experimental areas and all sub-systems of the FRS
  • Development of an own research profile within the framework of the Super-FRS Experiment Collaboration
  • Scientific-technical support during preparation and execution of experiments, supervision of external user groups and integration of their experiment detectors

Education and experience requirements

  • PhD in the field of experimental nuclear physics, accelerators, particle or high energy physics
  • At least three years of experience with magnetic spectrometers and related beam-transport systems, heavy-ion and radiation detectors, nuclear physics electronics or data acquisition and analysis systems Ability to design experiments combining magnetic spectrometers with complex detector systems, experience with ion-optical design simulations
  • Self-motivated, able to lead an experiment team and to work well within the team
  • Excellent communication, planning, and organizational skills  

Desired qualifications

  • Experience with simulation codes (MOCADI, GEANT, etc)
  • Experience with vacuum equipment, superconducting magnets and cryogenic detectors

The position is a tenure-track position, initially limited to a duration of five years, with the goal to transfer in an unlimited employment after positive evaluation. Salary is equivalent to that for public employees as specified in the collective agreement for public employees (TVöD Bund).  

GSI promotes the professional development of women and therefore expressly welcomes applications from women. Severely disabled persons with equal qualification are given preference.

Handicapped persons will be preferentially considered when equally qualified.
