Zusammenfassung

European XFEL in Germany invites applications for a Postdoctoral Researcher to support a joint team of scientists and engineers from European XFEL and DESY.

You will develop and operate the XFELO demonstrator, contribute to tunable XFELO design, plan experiments, analyze data, and help disseminate results through publications and internal notes.

Qualifikationen

• PhD completed by the start date in a relevant field.
• Proven research record with publications and conference contributions.
• Hands-on experience in FELs, optical cavities/oscillators, X-ray optics, accelerator or beam diagnostics, or beamline instrumentation at a large-scale user facility.
• Strong data analysis and programming skills (Python, MATLAB, C/C++ a plus).
• Excellent communication skills in English and ability to work in an interdisciplinary team.

Aufgaben

• Develop, optimize, and operate the XFELO demonstrator setup (hardware, beamline components, experiments).
• Contribute to the design of a tunable XFELO device and perform performance studies.
• Plan, prepare, and execute XFELO-related experiments, including collaborations with user groups.
• Analyze data, document results, and contribute to publications and internal reports.
• Co-organise and support workshops and meetings on XFELO science and development.

Jobbeschreibung

Recent advances at the European XFEL have enabled lasing in a cavity-based X-ray free-electron laser oscillator (XFELO). This milestone opens new perspectives for X-ray generation and high-precision experiments. To advance the XFELO program to the next level, we are seeking a highly motivated Postdoctoral Researcher to support a joint team of scientists and engineers from European XFEL and DESY.

For our X-Ray Optics group we are looking for an

Responsibilities

• Further develop, optimize, and operate the existing XFELO demonstrator setup (hardware, beamline components, and experimental procedures).
• Contribute to the conceptual design of a tunable XFELO device, including performance studies, technical trade-offs, and interface definitions.
• Plan, prepare, and execute XFELO-related experiments - both internal measurements and experiments in collaboration with internal and external user groups.
• Analyze experimental data, document results, and contribute to publications, internal reports, and technical notes.
• Co-organise and support workshops and meetings related to XFELO science, technology, and future development (agenda, speakers, documentation, follow-up actions).

Requirements

• PhD in Physics, Accelerator/Photon Science, Engineering, or a closely related field (completed by the start date).
• Demonstrated ability to conduct and publish high-quality research (e.g., peer-reviewed publications, conference contributions).
• Hands-on experience in at least one of the following areas: free-electron lasers (FELs), optical cavities/oscillators, X-ray optics, accelerator or beam diagnostics, beamline instrumentation, or experimental operation at a large-scale user facility.
• Solid understanding of X-ray optics and fundamentals of FEL and accelerator physics relevant to XFELO operation.
• Strong data analysis and scientific programming skills (e.g., Python; MATLAB and/or C/C++ are an advantage).
• Excellent communication skills in English (written and spoken) and the ability to work effectively in an interdisciplinary, international team.

Become part of a vibrant international and multi-cultural team of scientists, engineers, technical and administrative staff. Be involved in cutting edge scientific and technical progress and participate in our international networks. Experience our atmosphere of tolerance and respect.
