Master Thesis - The long shadow of X-rays
Do you want to be part of advanced research, development and manufacturing of the world's brightest X-ray source? We have an opening for a Master Student within Physics, Engineering Physics, Electrical Engineering or similar. In this project you will learn about and get hands-on experience from computer-based source control and X-ray characterization.
Project Background
Excillum develops and manufactures the X-ray tube with the world's smallest spot, and the most precise control of the electron optics beam. Nevertheless, there are a lot of uncertainties reamining to be investigated! In particular, how the electron beam is translated into an X-ray spot.
X-ray spots are often characterized by a single number, its spot size, which often assumes a Gaussian distribution. We know it is not fully Gaussian. Your task will be to map out and understand just how non-Gaussian it is, and in which ways.
The project outline:
- Onboarding, understanding the X-ray tube, and proposed measurement methodology
- Conducting measurements that will be used to model the X-ray spot: Variations in acceleration voltage, spot size, target thickness, spectrum filtering, X-ray tube cathode, and measurement conditions
- Data analysis and model creation
- If time and if we find a partner: Measure non-Excillum sources in other labs in Sweden or abroad.
- If time: Monte-Carlo simulations to compare to measurements
- If time: Translate the new models of X-ray spot behaviour into expectations for resolution and contrast.
Thesis level: Master, 30 hp.
