- Abstract
- The purpose of this project was to develop a better understanding of the re- sponse of a pixelated thermal-neutron detector, which will be used as a thermal- neutron detector at one of the beam lines at the European Spallation Source in Lund, Sweden. The detector consists of a thin Lithium6-glass scintillator, a multi-anode photomultiplier tube and associated read-out electronics. Initial characterizations of the response to laser light and a collimated alpha-particle beam were performed in collaboration with the Department of Nuclear Physics at the University of Glasgow. The response of the prototype to the laser light was demonstrated to be reproducible. The absolute gain for each pixel provided by the manufacturer for the multi-anode... (More)

- Popular Abstract
- Neutrons are small particles with no charge. Together with protons, they are what makes up the nuclei of the atoms. The fact that neutrons have no charge makes them excellent to use as probes in material science. This is what researcher are planning to do at the European Spallation Source (ESS) which is currently being built in Lund, Sweden and is expected to be finished in 2023. This project is about how you detect these neutrons after they have interacted with a sample.
