Assessment of Thermionic RF Electron Gun

The Canadian Light Source produces a very bright light which can be used to study DNA, viruses, cells, proteins, and other small-scale structures. To generate this light, the CLS needs a beam of electrons which are generated by an electron gun. In 2018, this electron gun failed, and the facility was unable to function for 6 months while it was replaced. The CLS had purchased a more reliable electron gun which uses different technology to generate electrons.

Establishment of an X-ray CT and FTIR mouse brain reference atlas

The intern will construct a 3D atlas of the mouse brain, constructed using multiple biomedical and chemical imaging techniques. The atlas will aid visualization of the 3D distribution of brain metabolites and biomolecules.. The atlas will be a powerful research and teaching resource with its multi disciplinary approach to processing and visualizing data collected at the Canadian Light Source (CLS) synchrotron. Biochemical imaging of the brain’s regional composition and metabolic processes will reveal new structural and functional information.

In-Situ X-Ray Imaging of Carbon Fibre Composite Manufacturing Processes

Carbon fibre composites are a family of lightweight, high-performance materials that consist of high-strength carbon fibres embedded in a resin. These materials are used in a variety of demanding applications, such as aerospace, automotive, and marine sectors. The reduction of material weight in these transportation industries results in improved energy efficiency and reduction in greenhouse gases.

Synchrotron imaging of Saskatchewan amber and dinosaur fossils

Saskatchewan has a rich Late Cretaceous fossil record (~66 million years ago), which provides opportunities to study both fossilized resin (amber) and dinosaur skeletons from shared habitats. Synchrotron X-rays are a powerful new tool that can be used to CT scan fossils and create 3D models of microscopic structures, and to map out the chemistry of preserved material. The proposed project will use synchrotron techniques to 3D-model insects in amber for new species descriptions, and to explore how soft tissues are preserved within these specimens.

Evaluating the possibilities for a new generation light source for infrared spectroscopy and spectromicroscopy

Infrared spectroscopy is a fundamental technique to study novel materials ranging from medicine to semiconductor industry. Regular infrared sources can provide very limited spatial resolution for infrared microscopy experiments. Currently, this limitation can be overcome with the use of synchrotron sources. A recently discovered and now commercially available alternative light source is the Quantum Cascade Lasers  (QCLs). Their limitation is that QCLs have a small range of tunability.

Simulation of a Liquid Helium Cryogenic System

This project aims to expand on an existing computer model of a liquid helium cryogenic system located at the Canadian Light Source (CLS) in Saskatoon, Saskatchewan. There are two facets to this work. The first facet is to modify and use the model to answer certain questions CLS staff members have regarding proposed cryogenic system changes and upgrades. The answers to these questions are important in helping CLS staff make decisions regarding these proposed upgrades. The second facet is to improve the coding on the current model by using established computational packages.
