The FRS/SFRS Experiments Department is central for many nuclear physics experiments at GSI/FAIR. It operates the FRS fragment separator for the production and investigation of exotic atomic nuclei and their properties within the framework of the NUSTAR collaboration. It prepares for novel experiments at the next-generation super-conducting fragment separator Super-FRS of the international accelerator facility FAIR. The equipment needed for this is currently being installed at the Super-FRS experiment area so that it will be available for experiments at FAIR during the ‘Early Science’ and ‘First Science’ phases: the Super-FRS Ion Catcher at the high-energy branch and a detector system for reaction and decay experiments at the mid-focus of the Super-FRS.

For the commissioning of the new detector systems with and without beam, as well as for the planned experiments at the Super-FRS, the ‘FRS/SFRS Experiments’ department is looking for a PhD physicist.

The main tasks include:

• Integration (mechanical, vacuum technology, electrical, safety, functional, control technology, supply technology) of the new equipment for the Super-FRS experiment collaboration at Super-FRS at FAIR
• Commissioning in the new FAIR environment, initially without beam, later with beam; testing of function and performance; verification of specifications; documentation of results; commissioning with increasing beam intensity under realistic experimental conditions with the new beams of the Super-FRS
• Safety-related preparation, integration and acceptance of the new systems at FAIR (general occupational and operational safety, specific issues such as the operation of cryogenic systems, handling of radioactive sources, etc.), preparation of risk assessments, implementation and review of all relevant safety measures in connection with the operation of the new systems
• Preparation and performing of the ‘Early Science’ and ‘First Science’ phases for initial experiments of the Super-FRS Experiment Collaboration.
