Postdoc Positions in Attosecond Pulse Generation at EuXFEL

For our location in Hamburg we are seeking: Postdoc Positions in Attosecond Pulse Generation at EuXFEL Remuneration Group 13 | Limited: 3 years | Starting date: 04.01.2027 | ID: MPO007/2026 | Deadline: 30.11.2026 | 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. The European XFEL is one of the world's leading free-electron laser facilities and provides intense X-ray pulses with durations down to the attosecond regime. A dedicated strategy program has been established to further develop and exploit these ultrashort pulses, including through recruitment of new expertise. The positions focus on advancing existing techniques for short-pulse generation in terms of power, pulse duration and stability and both the hard and soft x-rays. Key areas of research include: - Independent control of transverse and longitudinal dispersion - Development of advanced pulse-shaping techniques - Advancing the use of existing longitudinal diagnostics for short-pulse characterization About your role: These positions combine scientific R&D with hands-on machine development and operation, providing the opportunity to take new FEL concepts from simulation through experimental validation to routine operation. - Conduct simulations and eventual experiments towards short pulse production at the EuXFEL - Actively support other attosecond generation activities - Communicate results and insights through presentations, reports and publications - Encouraged to develop and pursue their own ideas - Contribute to the reliable daily operation of the facility as an operator About you: - PhD in physics or related field with a background in accelerator or FEL physics - Experience with relevant FEL simulation codes - Good communication skills and a collaborative approach to working in an interdisciplinary team - Good command of English, German is beneficial - Experience in attosecond pulse generation - Practical experience in the FEL field - Experience in cathode shaping, fresh-slice or laser beam modulation Good reasons to join: Look forward to a unique working environment on our international research campus. Respectful cooperation and the well-being of our staff are central to us, with gender equality forming a key part of this commitment. To support work life balance we offer flexible working hours, variable part-time, job-sharing models and participation in mobile work (up to 50%).
