DESY, with its more than 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 project aims to advance the ptychography technique by parallel illumination of the sample by several focused beams to utilize an incoherent fraction of the synchrotron beam to speed up the experiment. The main goal is to bring the performance of multibeam ptychography to a general user level for routine operation.
