Magnetic Barkhausen Noise Measurements Using Tetrapole Probe Designs
(2014-12-23)
A magnetic Barkhausen noise (MBN) testing system was developed for Defence Research and Development Canada (DRDC) to perform MBN measurements on the Royal Canadian Navy’s Victoria class submarine hulls that can be correlated ...
Calibration Hardware Research and Development for SNO+
(2014-06-02)
The SNO+ experiment is a kilo-tonne scale liquid scintillator detector located at SNOLAB in Sudbury, Ontario, Canada. As the successor to the Sudbury Neutrino Observatory, SNO+ will use linear alkylbenzene (LAB) as the ...
Optical Properties of Individual and Bundled Single-Walled Carbon Nanotubes
(2014-09-13)
Single-walled carbon nanotubes (SWCNTs) are nearly ideal one-dimensional systems, with aspect ratios exceeding 10$^{5}$:1.
The band gap of a SWCNT, determined by the species, covers the majority of the visible spectrum ...
The Evolution of Star Formation Activity in Cluster Galaxies Over 0.15 < z < 1.5
(2014-10-01)
In this thesis, we explore 7.5 billion years of evolution in cluster galaxy star formation activity using a sample of 11 high-redshift (1 < z < 1.5) clusters from the IRAC Shallow Cluster Survey, and 25 low-redshift (0.15 ...
The Methodology of Modelling the Milky Way with Stellar Streams
(2014-10-01)
In this thesis we examine the methodology of modelling the Milky Way using stellar streams. Using the orbit-fitting method we show that combining constraints from the Sagittarius stream with a suite of other photometric ...
Crossed-Array Transducer for Real-Time Three-Dimensional Ultrasound Imaging
(2014-12-02)
Volumetric ultrasound imaging can present numerous advantages to medical diagnostics, such as increased spatial context, better long-term patient tracking, and reduced imaging times. Creating three-dimensional ultrasound ...
The Development of the SNO+ Experiment: Scintillator Timing, Pulse Shape Discrimination, and Sterile Neutrinos
(2014-04-29)
The SNO+ experiment is a multi-purpose neutrino detector which is under construction in the SNOLAB facility in Sudbury, Ontario. SNO+ will search for neutrinoless double beta decay, and will measure low energy solar ...
Early development of a test-bed to measure fractoluminescence in scintillators & simulation of a Na-24 source for the SNO+ experiment
(2014-06-24)
This thesis consists of two parts; the first part pertains to fractoluminescence as a potential background in crystal scintillator detectors, and the second part bears on the simulation of a 24Na source to be used during ...
Radiopurity measurement of acrylic for the DEAP-3600 dark matter experiment
(2014-01-16)
The liquid argon target of the DEAP-3600 dark matter detector is contained by an extremely radiopure acrylic vessel. Alpha decays from the inner surface of the acrylic vessel are a source of background. If a fraction of ...
Terahertz driven intraband dynamics of excitons in nanorods
(2014-05-15)
Quantum dots and nanorods are becoming increasingly important structures due to their potential applications that range from photovoltaic devices to medicine. The majority of the research on carrier dynamics in these ...
