GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt operates one of the leading particle accelerators for science. Currently, 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.

Since 2008, GSI is operating PHELIX, the largest laser facility in Germany, for the international scientific community. The facility is a dual front-end nanosecond and sub-picosecond laser that benefits from the worldwide unique combination of expertise in laser and heavy-ion physics located around Darmstadt.

To maintain PHELIX’s attractiveness and prepare the next generation of high-energy lasers, GSI and FAIR have started a EU funded project named THRILL (Technology for High-Repetition-rate Intense Laser Laboratories) with eight other partners in Europe. The THRILL project deals with providing new schemes and devices for pushing forward the limits of research infrastructures (RI) of European relevance and ESFRI landmarks. The project partners have identified several technical bottlenecks in high-energy high-repetition-rate laser technology that prevent it from reaching the technical readiness level required to technically specify and build the needed devices. Details can be found on the project web page https://www.thrill-project.eu/

Therefore, we are offering aposition as

Physicist or Engineer (all genders) at the PHELIX facility

Posting ID: 24.67-1700

to perform research within the THRILL project in a small research group.

Your tasks:

• Development/Improvement of Nd:glass based laser amplifier heads which are actively cooled by a suitable liquid
• Investigation of the mechanical and optical effects both in simulations (e.g. ANSYS, possibly COMSOL or similar Multiphysics tools) and in the laboratory on a dedicated test stand for optical wave front measurements
• Good knowledge in high-energy high-intensity laser physics is necessary in both theory and practice

Since the project is shared among European partners, frequent short-term visits and staff exchanges are foreseen.

In addition, the candidate will be integrated in the PHELIX operation team and will be trained as shot director/operator for the normal operation of PHELIX.

Your profile and desirable qualification:

• University degree as Physicist or Engineer (mechanical/optomechanical engineering) or a related field or a comparable qualification
• Experience in work in laser environments, preferably high-energy laser systems
• CAD experience, e.g. Autodesk Inventor, CATIA
• Data taking and analysis with electric and electronic sensors like cameras, temperature and pressure sensors
• Experience in mechanical lab work on liquid cooling circuits, large-size optics and optomechanics
• Basic knowledge of optical wave front measurement and compensation techniques
• A strong interest to work in an international environment and excellent team-working capability

New development ideas based on the candidate’s experience are also welcome if they meet the institute’s mid- to long-term development goals. 

We offer an employment contract with a duration until Dec. 31^st 2026, starting ASAP. The salary is based on the German civil service employees (Tarifvertrag für den öffentlichen Dienst - TVöD (Bund)).

GSI supports the vocational development of women. Therefore, women are especially encouraged to apply for the position.

Severely handicapped persons will be preferentially considered when equally qualified.

For further information contact Prof. Dr. V. Bagnoud (v.bagnoud(at)gsi.de) or https://www.gsi.de/pp.

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

Interested candidates can send their application with a description of the research interest and underline how this fits with the goals of the THRILL project and the near term goals of the laser and plasma physics program of GSI with the Posting-ID24.67-1700 by 05.06.2024 at the latest
