IMT 09-2022 Master Thesis Design and testing of the world’s first NMR and X-ray imaging correlative characterization probehead at CORREL Lab
Institut für Mikrostrukturtechnik (IMT)
CORREL Lab stands for the “correlative characterization laboratory” and is a state-of-the-art facility newly built at the Institute of Microstructure Technology (IMT) where nuclear magnetic resonance (NMR) and X-ray imaging (XRI) investigations will be performed on the same sample, in the same location and at the same time. The advantage of this unique approach is to gather complementary information about dynamic processes. NMR provides exquisite information about the chemical composition of a sample, while XRI provides information about the structure and structural modifications of the sample. Dynamic processes are processes which evolve in time, therefore the sample cannot be measured in a sequential manner, i.e., by transferring it between two different measurement locations, one for NMR, the other for XRI characterization. Examples of dynamic processes to be studied are: polymerization processes, self-healing materials, electro-chemical reactions, catalytic reactions.
CORREL Lab is equipped with a 7T horizontal bore magnet (similar to what is being used in hospitals for clinical investigation of human patients with magnetic resonance imaging – MRI) for NMR characterization and an Excillum X-ray source for XRI measurements. The optical axis of the X-ray setup passes right through the middle of the NMR magnet bore, so that a sample undergoes simultaneous X-ray imaging while it is being analyzed by NMR.
The main goal of the Master thesis is to design and test the world’s first NMR and X-ray imaging correlative characterization probehead at CORREL Lab.
This is a task which comes with multiple challenges related to the construction of the probehead, requiring a unified approach that takes into account optical, mechanical and electrical engineering aspects: for example, space constraints inside the bore of the magnet, the use of non-magnetic materials, the use of materials with low absorption in the X-ray spectrum etc.
Are you passionate about physics and engineering in general, and more specifically about the intersection of various domains in one single experiment? Are you ready to challenge yourself to build the world’s first NMR and X-ray imaging correlative characterization probehead? If the answer is “yes”, we are looking for you!
The specific tasks within the project will be: (i) design of a simple proof-of-concept experiment to be investigated by both NMR and XRI at the same time; (ii) fabrication in an NMR- and X-ray-compatible manner of a probehead including the sample holder for the proof-of-concept experiment; (iii) probehead testing. During the Master thesis, you will get hands-on experience on NMR and X-ray imaging characterization basics, design and manufacturing techniques, having the opportunity to get exposure to a wide range of instruments and techniques.
You will be integrated in the larger team of the Spin & Photon Applications (SPA-) Laboratory. Within this project, you will use the infrastructure existent at the Institute of Microstructure Technology (IMT), i.e., microfabrication facilities, RF testing equipment, and state of the art 7T NMR scanner. This is a complete project, offering the possibility to fabricate and test the devices, giving you the opportunity to co-author conference and/or journal publications.
