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.

The planned upgrade of the high-brilliance synchrotron radiation source PETRA III with a new multi-bend achromat lattice will provide unprecedented brightness and coherence properties for hard X-rays at PETRA IV. Diagnosing the X-ray beam quality at the beamlines is an essential step to optimize the performance of each instrument. The PhD position is part of the technical design phase for PETRA IV and will explore fast online wavefront and coherence analysis for future beamlines.
