Desktop MRI Console
In modern MRI courses there is a severe lack of hands on interactions with clinical MRI machines due to the high cost of the equipment. The goal of this three phase project is to design a desktop sized MRI scanner to be used...

Axion Electrodynamics
Axions were introduced in particle physics in the 1970s to explain CP violation in the standard model. Subsequently axions have become a leading candidate for dark matter in Cosmology. The axion field has an unusual coupling to electromagnetism leading to remarkable electromagnetic phenomena that...

Design and Implementation of a Low Cost Malaria Diagnosis Device
A major challenge in malaria diagnosis is the need for a cheap, portable device capable of detecting low concentrations of the malaria pigment, hemozoin. The malaria parasite converts hemoglobin in the blood into...

The Relativistic Hofstadter Problem
Hofstadter studied electrons in a strong magnetic field perturbed by a weak periodic potential on a square lattice. He found that the energy levels plotted as a function of the magnetic field formed a beautiful pattern with a recursive structure now Hofstadter...

Can We Use Sound Perception to Identify Rupture Patterns in Earthquakes?
The processes by which earthquakes occur is poorly understood. In more detail, an earthquake results from the relative motion of blocks of crust, or pieces of tectonic plates, across a...
Dylan Yurgionas with Dan Akerib and Tom ShuttModeling Gamma Ray Background from LUX Characterization of background is important for finding WIMP recoil events. Based on their cross sections, WIMPs will only scatter once inside the two phase xenon detector, LUX. Incident gamma rays from trace radioactive impurities in detector...

Capacitive level sensors for use in liquid xenon detectors
The LUX dark matter experiment liquid xenon detector uses an electric field created by grids to increase the drift velocity of electrons into xenon gas causing them to produce additional scintillation photons. These photons...

Conductors as a model for elliptical coffee stains
In electrostatics, conductors exhibit a number of interesting properties. Among these is the ‘lightning rod’ effect, whereby electric fields are significantly greater near areas of high curvature. In 1997, Nagel et al. published a paper likening the behavior...

Aluminum zinc oxide transparent conductors for optical cavity enhanced polymer photovoltaics
Indium tin oxide is the ubiquitous transparent conductor used in all liquid crystal displays and thin film photovoltaic devices. Indium, however, is a rare and relatively expensive material, leading to intense research to replace it...

Design, fabrication and testing of a new limiting oxygen index device
The Limiting Oxygen Index (LOI) is one of an array of commonly used metrics for the rating of material flammability. Although devices to measure this value are commercially available,...
