Master Thesis at Excillum - spring 2026
Exploring a novel imaging concept for X-ray nano-tomography
Do you want to help shape the future of high-resolution X-ray imaging?
Excillum develops the world’s brightest laboratory X-ray sources. We’re looking for a master’s student in Physics, Applied Math, or Computer Science who’s excited about scientific X-ray imaging, image processing, and experimentation.
Project Background
This project is part of our application team, developing and demonstrating use cases of our products. You’ll work with the Excillum NanoTube N3 transmission X-ray source in our application lab. Its exceptionally stable, round focal spot and precise e-beam control open up new ways to push true nano-resolution tomography.
Challenge: We’re exploring a novel acquisition strategy for nano-tomography that leverages unique source capabilities (beam/spot control and stability) to improve reconstruction quality and/or throughput. The work is conceptual and exploratory, with lab validation.
What you'll do
- Develop acquisition scripts (Python preferred) to control the NanoTube N3, motion stages, and the X-ray detector; handle metadata logging and basic fault handling.
- Plan and run lab experiments using your scripts; design clean measurement series that isolate key effects and answer the research questions.
- Implement and evaluate image correlation/registration and validate with synthetic tests.
- Perform tomographic reconstructions using existing software; compare against baselines using quantitative metrics.
- Communicate results with clear figures, quantitative analysis, and a thesis-ready methods section (co-supervision and reviews provided).
Who you are
- A master’s student (final-year) in Physics, Applied Math, EE/CS or similar.
- Comfortable coding in Python (NumPy, SciPy; bonus for hardware control/async I/O).
- Scientifically minded: you design clean experiments, control variables, and analyze uncertainty.
- Curious about image processing (registration, filtering, metrics) and willing to learn what you don’t know.
- Meriting: Experience with tomography or imaging systems (synchrotron, micro-CT, SEM/TEM, medical imaging, etc.).
To apply to this project, please attach CV and relevant grades. We look forward to your application!
