About the workplace
DESY is one of the world's leading research centres with more than 2,700 employees at its two locations in Hamburg and Zeuthen. Its research focuses on decoding the structure and function of matter from the smallest particles of the universe to the building blocks of life. DESY offers cutting-edge research infrastructure, interdisciplinary research platforms and international networks to create a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.
About the group
The x-ray tomography group is based on a collaboration between the University of Siegen and DESY. Our goal is to combine the expertise in material and nano science at the University of Siegen with the modern x-ray methods from Desy in Hamburg.
About the project
Develop with us the next generation of x-ray lenses.
Radiation damage poses a significant challenge to x-ray microscopy, especially biological samples quickly show damage if the x-ray dose is too high. New, more efficient lenses that cause less radiation damage make it possible to study radiation-sensitive samples as well. The goal of this project is to develop high-resolution optics that can capture more information with a lower radiation dose.
The workplace is at DESY in Hamburg. DESY has long-standing experience in the development and construction of x-ray optics and operates one of the world's best x-ray sources, PETRA III. You will work closely with the "X-Ray Nanoscience and X-ray Optics" group and the beamline P06 to develop and test new optics in experiments.
You will test and improve new lens designs with simulations. You will also coordinate the construction of new lenses, plan, and perform experiments at PETRA III and other x-ray sources. You will present your results at international conferences and publish them in peer-reviewed journals.
Your responsibilities
4. development of new x-ray optics in the project "Annular apertures for dose efficient focusing of X rays" (BMFTR project: 05K25PS2)
5. design and perform synchrotron experiments
6. assist in synchrotron experiments at Petra III and other synchrotrons
7. publish peer-reviewed publications
8. present results at international conferences
This is a position to obtain a PhD (doctorate). Opportunities for this will be provided as part of the position responsibilities.
Your profile
9. diploma or master degree in physics (or related field) with good or very good grade (finished or in the final phase)
10. strong written and oral communication skills in English+
11. strong knowledge with scientific programming (Python, MATLAB, C++, or others)
12. work well both independently and in multi-disciplinary, international collaborations
Beneficial skills
13. you are creative and enjoy solving problems
14. background in optics
15. experience with synchrotron experiments
16. prior publications
17. interest in combining theoretical and practical work
We offer
18. Promotion of own scientific or artistic qualification according to the Wissenschaftszeitvertragsgesetz [act on temporary employment in higher education] (e.g. PhD)
19. Diverse opportunities to take on responsibility and make a visible contribution in the research and teaching environment
20. A modern understanding of leadership and collaboration
21. Good work-life balance, for example, through flexible working hours and work location, as well as support with child care
22. Extensive personnel development program
23. Health management with a wide range of prevention and counseling services
