Postdoc (w/m/d) for X-Ray Ptychography at BESSY II

Your Tasks

• You will set up and commission a ptychography solution for the two STXM instruments MAXYMUS and MYSTIIC at BESSY II, using state-of-the-art X-ray detectors and advanced reconstruction methods.
• You will develop software for experiment control, data acquisition and data analysis, and automate measurement procedures including remote operation of the experiments.
• You will optimise ptychographic detection and reconstruction methods, collaborating with external companies on adapting the detector systems.
• You will plan, carry out and analyse experiments together with internal and external user groups and train users in operating the microscopes.
• You will investigate magnetic nanosystems using soft X-ray ptychography and tomography, and present and publish your results at international conferences and in peer-reviewed journals.

Your Profile

• Completed PhD in physics, electrical engineering, materials science or an equivalent field of research
• Experience in ptychography and/or scanning transmission X-ray microscopy (STXM) and in computational phase reconstruction (ptychography/tomography), including the use of HPC clusters
• Programming skills in data processing and hardware control (e.g. Python, Labview, Matlab, C++)
• Project management experience: setting goals, prioritising tasks, and meeting deadlines and budgets
• English language skills at C1 level or higher, written and spoken
• Ideally, experience with optical, cryogenic and ultra-high-vacuum systems and in collaborating in international project teams
