FABRICATION AND THERMAL ANALYSIS OF POLYIMIDE-BASED X-RAY MASKS AT THE SYNCHROTRON LABORATORY FOR MICRO AND NANO DEVICES, CANADIAN LIGHT SOURCE
… for Micro and Nano Devices (SyLMAND) at the Canadian Light Source (CLS) is a DXRL laboratory with continuous tuning capabilities for spectrum and power of the synchrotron beam. X-ray mask fabrication is one of the most demanding sequences associated with the entire processing chain and has …

An Effective Polychromatic X-ray Beam for Quantitative Analysis of Fossil Compositions
… X-ray Fluorescence data collected at the Canadian Light Source in Saskatchewan, Canada. Several methods to facilitate both qualitative and quantitative analysis of this data are used and developed. In particular, a method for replacing a polychromatic X-ray spectrum with an effective set …

Studies of Coherent Synchrotron Radiation with the Discontinuous Galerkin Method
… DG motivated by an experiment performed at the Canadian Light Source. A comparison between theory and experiment has been published (Phys. Rev. Lett. 114, 204801 (2015)). Lastly, we devise a novel approach to integrating Maxwell's equations with 3D DG using a Galilean transformation and …

Developing Time-Resolved Synchrotron Infrared Spectroscopy for Spectroelectrochemical Measurements
… compatible with the mid-IR beamline at the Canadian Light Source to study irreversible electrocatalytic processes with rapid scan FTIR in reflection mode. The thesis demonstrates application of SIR-based rapid scan FTIR to spatially map catalytic activity on heterogenous PtNi electrode and …

Surface-Enhanced Spectroelectrochemistry using Synchrotron Infrared Radiation
… requires an unconventional infrared source, namely highly focused synchrotron radiation. This thesis will present the characterization of a new internal reflection element which is fully compatible with ATR-SEIRAS and easily amenable to microfabrication. A custom horizontal microscope …

Magnetostatic Modelling and Measurement for Particle Dynamics of a Magnetic Energy Filter
… electrons from beams produced by electron sources. Two electron source configurations—based on a direct current (DC) 0.5 MeV electron gun and a 3.5 MeV radio frequency (RF) electron gun available at the Canadian Light Source (CLS) test laboratory—were examined. Magnetostatic simulations …

Authentic Scientific Inquiry, Student Engagement, and Transformational Learning: Are They Related?
… inquiry using techniques offered by the Canadian Light Source (CLS). Canada’s synchrotron is a national science research facility that generates intense beams of x-ray and infra-red light to probe the structure and function of matter. The nature of the SotB program, involving high school …

Coherence Control and Measurement at the CLS Using X-ray Interferometry
As synchrotron light source storage rings transition to multi-bend achromat (MBA) lattices for higher brightness and coherence, emerging challenges arise in beam diagnostic tools that accurately monitor and control the spatial degree of coherence. MBA lattice designs in modern fourth generation …

Development of X-ray Coherent Scatter Projection Imaging Systems
… group's previous work and was configured at the Canadian Light Source synchrotron. It employed five 33.2 keV pencil beams in combination with continuous object motion. The system consisted of a primary collimator, motorized stages for object translation, a flat-panel x-ray detector for measuring …

Developing a Microbubble-based Contrast Agent for X-ray Phase Contrast Imaging to Detect Neovasculature in Breast Cancer
… (low). MBs were imaged by synchrotron at the Canadian Light Source with In-line phase contrast imaging (PCI) and Multiple-image Radiography (MIR). The refraction contrast in PCI was measured by detecting phase object numbers and comparing the mean pixel values (MPV: 0/255) of MBs to agar in …

THE SHORT- AND LONG- TERM EFFECT OF ZINC AND COPPER CONTAMINATION ON SOIL MICROBIAL FUNCTIONS
… a part of all site investigations carried out by Canadian risk assessors. One of the key factors influencing the cost and therefore the scope and size of any potential investigation is the transportation of soils from a site to laboratories for experimentation. Therefore, a low soil requirement …
