DESY offers challenging tasks in an international setting

For versatile and challenging tasks in an international environment DESY is seeking dedicated employees in the field of natural sciences, engineering and also in the technical and commercial sector.

For our location in Hamburg we are seeking:

Postdoctoral Researcher for the PETRA IV Beamline Technical Designs

Remuneration Group 13


DESY, with its 2700 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.

DESY is developing PETRA IV, the ultimate X-ray microscope for nanoresearch with outstanding potential for industrial users and socially relevant applications in energy research, information technology, mobility, environment and medicine. PETRA IV will enable highest resolution for experiments on relevant length, time and energy scales, with a very high degree of coherence, highest brightness, as well as with all options for in-situ/operando analysis.

The PETRA IV work package WP3.08 is responsible for the PETRA IV beamline portfolio and experiments. This involves a concept development of the beamline selection process, management and organization of the work package groups within the WP3, and the development of the PETRA IV beamline technical design.

For the development of the PETRA IV beamline technical design, we are seeking a scientist to assist the beamline managers with the beamline optical designs using ray-tracing and wave propagation simulation tools.

The position

  • Work as part of the team and assist PETRA beamline managers with the beamline design (ray-tracing, wave propagation)
  • Development and conceptioning of PETRA IV beamline design options
  • lncorporate effects of non-ideal beamline optics and heat-load into the beamline design options
  • ldentification and determination of spatial coherence degradation effects caused by non-ideal beamline optics
  • Beamline design optimizations and refinements


  • PhD in physics or equivalent field or qualification
  • Expertise and skills in beamline ray-tracing and wave propagation simulation tools (e.g. Xrt, SRW, OASYS, Shadow)
  • Expertise in beamline optics design
  • High degree of experience and expertise in the field of optics
  • Good programming skills (Python, Matlab)
  • Excellent teamwork abilities in an international environment
  • Excellent communication skills
