The accurate measurement of time is of critical importance to society as it provides the means to synchronize events in our lives. The world has ever-increasing demands for precise time in fields such as automation, energy grids, smart cities, financial markets, fundamental research, and global positioning and navigation. Since the world moved to an atomic definition of time in the 1960s,...
This project focuses on the investigation of trap energy levels introduced by radiation damage in epitaxial p-type silicon. Using 6-inch wafers of various boron doping concentrations (1e13, 1e14, 1e15, 1e16, and 1e17 cm$^{−3}$) with a 50 µm epitaxial layer, multiple iterations of test structures consisting of Schottky and pn-junction diodes of different sizes and flavours are being fabricated...
HELIX, the High Energy Light Isotope eXperiment, is a balloon-borne payload designed to measure the isotopic abundances of light cosmic ray nuclei. Precise measurements of the 10Be nuclear isotope from 0.2 GeV/n to 10 GeV/n will help study propagation processes of cosmic rays. These measurements will allow the refining of propagation models, critical for interpreting excesses and unexpected...
The ocean Sound Speed Profile directly affects how acoustic waves propagate in the ocean. As a result, knowledge of the sound speed profile is important in many underwater acoustic applications including acoustic imaging, source localization, and underwater communication. Measurement of ocean sound speed can also provide an indirect measure of ocean temperature using the close dependence of...
