Job description

X-ray ptychography is a novel imaging technique which enables 3D imaging of objects at a resolution down to nm scale. However, like most X-ray imaging techniques, it currently does not give elemental information, which makes it difficult to distinguish different material phases in materials engineering applications, for example battery materials and catalysts.

Within the Radiation Physics research group the use of hyperspectral X-ray detectors for X-ray imaging is investigated. This novel type of detector enables highly accurate measurement of the energy of individual photons hitting a pixelated array detector, giving us combined chemical and spatial information about materials being imaged. Recently, we made the first practical demonstration of the applicability of these detectors for such "colour” (or spectral) ptychography using synchrotron x-rays in a close collaboration with the beamline team of I13-1 of the Diamond Light Source and the University of Manchester, UK.

This research project aims to further develop and characterize this technique, and apply it in a number of important research areas such as battery materials, catalysts and beyond.

Profile of the candidate

We are looking for an independent and well-organized candidate with a Master of Science degree (preferably in Physics, Chemistry or Engineering) and a strong background in X-ray imaging or instrumentation. Good programming skills in scientific programming languages

(C++, Python) are highly recommended. You will work on a project that is a collaboration between the Radiation Physics research group, part of the Centre for X-ray Tomography ( and the beamline scientists at I13-1. Furthermore, the work will involve opportunities for multidisciplinary research, applying your developments on research questions in several aspects of materials sciences. Well-developed social skills directed towards working in an interdisciplinary team and excellent interpersonal and communicative skills (English) are therefore required. In the scope of the international collaboration, you will be travelling frequently to the UK national synchrotron facility.

We offer a full-time PhD scholarship for 48 months, starting between June 1st, 2020 and October 1st, 2020 (depending on the successful candidate’s availability). You will work in a multidisciplinary and international team of scientists and engineers, both in Belgium and UK. Furthermore, you will have access to a state-of-the-art X-ray imaging facilities of the Centre for X-ray Tomography as well as regular access to one of the few beamlines in the world capable of performing X-ray ptychography.

Applicants should elaborate their interest and possible experience in X-ray imaging, instrumentation and/or synchrotron radiation in their letter of motivation.

How to apply

Applications must contain the following documents (in English or Dutch) in .pdf format (note that other formats will be ignored!):

  •  A personal (motivation) letter
  •  Curriculum vitae.
  •  A list of publications (if available)

The documents should be sent by email to Prof. dr. ir. Matthieu Boone

() before April 30th, 2020, 13:00 using as subject of your mail ‘CoPtTo_PhD_your name’. We advise to submit your application or a statement of interest as soon as possible, as a decision may be taken before the deadline.
