Research Assistant / PhD Student Development HTS Magnet Systems part-time (65%) Reference number: 26.106-6352 (m/f/d)

The GSI Helmholtz Centre for Schwerionenforschung in Darmstadt operates one of the leading particle accelerator systems for science. The new FAIR plant (Facility for Antiproton and Ion Research) is currently being built in international cooperation, one of the largest research projects worldwide. GSI and FAIR offer the opportunity to collaborate in this international environment with a team of employees working daily to conduct science at world level. We are looking for an for the Superconducting Magnets & Testing Division (SCM) Research assistantin /Doktorand*in (d/m/w) Development of HTS magnet systems in parttime (65%) Reference number: 26.106-6352

Magnets based on normal line and low temperature superconductors are currently used at the GSI and FAIR. Superconducting accelerator magnets based on high-temperature superconductors (HTS) are a key for future accelerator systems both in terms of magnetic power and power consumption. At the existing GSI system HHT, for example, a normally conductive quadrupole magnet with a small aperture, which limits the power of the system, is to be converted by a superconducting HTS system with a large aperture. The aim is to develop such a new HTS magnet system. The job owner*in will work on the electromagnetic design of the quadrupole magnets with HTS technology and will write a promotion on the basis of the project results. The project is conducted under the supervision of GSI experts and in cooperation with partners from industry and/or science. One or more of the following topics will be dealt with on your initiative, and other topics will be dealt with in cooperation: Electromagnetic design of the HTS magnets including design of a prototype coil. Construction of the HTS magnet: thermomechanical simulations, definition of instrumentation, cryoengineering. Creation of production drawings of the magnetic system. Production line of the coils and the magnet. Testing the prototype coil and the magnet both at room temperature and under cryogenic conditions. Evaluation of the magnetic performance and documentation of the test results. Creation of technical documentation Coordination of technical structures, experts from other specialist departments or cooperation partners.

University degree (M.Sc.) in physics or applied physics. Advanced knowledge in at least one of the fields of mechanical engineering, cryotechnology, electrical engineering or comparable fields. Structured working with a high degree of self-initiative and motivation Good team and communication skills English language skills in word and writing, German language skills (B1/B2) are desirable Ideally experience in coordinating test activities Experiences in the field of superconductive magnetic technology and relevant technical systems and disciplines are advantageous and preferred to evaluate: (superconductive) magnetic technology: coil design, mechanical design and design, cooling techniques, instrumentation, quench detection and magnetic protection, electrical operation, electrical integrity (bswp. high-voltage strength). cryotechnology (thermomechanics) and low temperature physics Software CAD (e.g. CATIA) FEM (for example ANSYS for thermal and mechanical analyses)

A versatile, varied and demanding activity with interesting and diverse tasks. Teamwork and the will for training are essential for us.
