To address the need for X-ray optics with both collimating and wavelength-selective characteristics, miniaturized, reflective optics based on thin foils are a promising approach. Such systems can be used in diffractometry, X-ray spectroscopy, or X-ray microscopy as condenser optics for efficient sample illumination.

Institut für Mikrostrukturtechnik (IMT)

Job description

The development of X-ray optics and complex optical systems in collaboration with external partners is a core focus of the research and development activities at the Institute of Microstructure (www.imt.kit.edu/x-rayoptics.php; www.röntgenoptik.de).

You will have the following tasks:

• Design, simulation, and microfabrication of thin-foil X-ray mirror optics
• Experimental characterization of X-ray optical performance at the lab-based X-ray sources at IMT
• Collaboration with industrial and academic partners
• Dissemination of research results through presentations at internal seminars/workshops and international conferences, with particular emphasis on the publication of papers on the research topic in peer-reviewed journals

You will join an interdisciplinary and international research team working in a well-equipped cleanroom and dedicated X-ray laboratories. In addition to gaining comprehensive expertise in X-ray optics, you will receive thorough training in microfabrication and microstructure technology.

The position offers the opportunity to pursue a part-time doctoral degree.
