Development of a Novel Readout System for Radiochromic Film Dosimetry
(2014-09-02)
As radiation therapy treatment modalities continue to develop, patient dose delivery has become increasingly complex. The verification of dose delivery and the quality assurance (QA) to ensure that a prescribed dose is ...
Polarimeter for an Accelerated Spheromak
(2014-05-01)
A three-beam heterodyne polarimeter has been designed and constructed to measure line-integrated density and Faraday rotation of accelerated spheromak plasmas in the Plasma Injector 1 and 2 devices (PI-1, PI-2) at General ...
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 ...
Environmental Effects on Interacting Galaxy Pairs in the SDSS
(2014-09-16)
The cause of varying galaxy interaction outcomes in different environments is investigated using a sample of over 505,000 Sloan Digital Sky Survey Data Release 7 galaxies at $0.01<z<0.20$. The aim is to distinguish the ...
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 ...
Charge Density Waves and Electronic Nematicity in the Three Band Model of Cuprate Superconductors
(2014-09-09)
Cuprate superconductors exhibit very high critical temperatures, $T_c$, compared to those in the conventional superconductors. The doping at which $T_c$ is maximized is called optimal doping. Below this level, in the ...
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 ...
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 ...
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 ...
Optical And Acoustical Studies Of The Proposed PICO-250L Dark Matter Detector
(2014-11-20)
In the first part of this work I explore the possibility of using linear alkylbenzene, the buffer liquid for the future PICO-250L detector, configured as a liquid scintillator that could provide information on the background ...
