Scientist for Emittance Diagnostics at DESY

Limited: 2 years with the option of permanent employment | Start: 01.04.2026 | ID: MMA010/2026 | Deadline: 12.03.2026 | Full-time/Part-time

DESY, with more than 2900 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 operates the world's brightest storage-ring-based hard X-ray radiation source PETRA III which offers scientists outstanding opportunities for experiments with X-rays of exceptionally high brilliance since 2009. In order to keep up with increasing demand for high brightness, DESY is currently undertaking to develop a diffraction-limited light source PETRA IV. The appropriate preparatory work has to be done over the next few years which will include a very challenging design of beam diagnostics and instrumentation. The MDI (Machine, Diagnostics and Instrumentation) group is responsible for development and conception of electronical, mechanical, and (electro-)optical monitors which are used for the observation of particle beams with differing characteristics at the DESY accelerator facilities. More information about PETRA IV: PETRA IV

• Conceptual design of transverse beam profile monitors which allow to resolve beam profiles in the order of a few micrometers
• Design of diagnostic beamlines for synchrotron radiation in the visible and X-ray spectral region
• Development of modern beam diagnostic instrumentation for the DESY accelerators
• Planning and running of experiments for longitudinal and transverse beam diagnostics
• Leading of a development team

• Master's degree or PhD in physics or equivalent qualification, skills and experiences
• Several years of experience in accelerator physics and beam diagnostics, preferably in the field of beam profile measurements and radiation physics
• Good knowledge in the field of optics (Zemax OpticStudio, SRW), mechanics, and detector technology
• Experience with scientific software such as Python and Matlab is desirable
• Experience in leading a team
• Ability to communicate research results effectively, in English and German both orally and in writing, within the team and at international conferences
