The Quest For High Power Lasers: Forcing Mutual Coherence In Broad Area Diode Lasers, Jonathan R. Wurtz
The Quest For High Power Lasers: Forcing Mutual Coherence In Broad Area Diode Lasers, Jonathan R. Wurtz
Student Research Projects
This poster explains efforts to improve spatial beam quality of diode array stacks using an external optical feedback system to force coherence of individual diodes.
Understanding Thermometry At Low Temperature, Zain Abbas
Understanding Thermometry At Low Temperature, Zain Abbas
Student Research Projects
Cryogenics play a vital role in building a Dynamic Nuclear Polarization (DNP) target for electron scattering experiments. The target material temperature was monitored using thermometry in order to evaluate their stability for use in the low temperature cryogenic bath of a DNP target. In this project, I investigated there solutions and accuracies of carbon ceramic, Cernox, Allen-Bradley, and thermocouple sensors at five known temperatures.
Analyzing Heavy Photon Search Simulations To Determine The Potential For True Muonium Discovery, Chad N. Civello
Analyzing Heavy Photon Search Simulations To Determine The Potential For True Muonium Discovery, Chad N. Civello
Student Research Projects
The Heavy Photon Search (HPS) is a new experiment at Jefferson Laboratory to search for heavy photons, a particle predicted by dark matter and dark energy extensions to the Standard Model of particle physics, in the mass range of 20 MeV/c2 to 1000 MeV/c2 . The experiment also has the potential to discover true muonium, a bound state of a muon and an antimuon that is predicted to exist, but has never been observed. The true muonium atom should be produced by an electron beam incident on a target, such as the tungsten target used in the HPS …
Salt Marsh Values In A Changing World: Examining Sea Level Rise On Tidal Marshes With A Surface Elevation Table, Sarah Martina Tierney
Salt Marsh Values In A Changing World: Examining Sea Level Rise On Tidal Marshes With A Surface Elevation Table, Sarah Martina Tierney

Rising seas are threatening coastal communities and putting added pressures on the natural environment. Sea level rise rates are increasing on a global scale (from 1.7 to 3.2 mm/yr). Salt marshes are not only intertidal habitats acutely influenced by sea levels, but they also provide key ecosystem services such as: buffers against storm surges, habitat for wildlife, carbon dioxide storage, and pollutant filtration. In New England, salt marshes have built at a rate of 1 to 2 mm annually over the past 4,000 years, which has kept pace with sea level rise. However, we do not know if salt marshes …
Spdy Vs Http/1.1: An Empirical Evaluation Of Network Protocol Performance, Stephen Matthew Chambers
Spdy Vs Http/1.1: An Empirical Evaluation Of Network Protocol Performance, Stephen Matthew Chambers
Student Research Projects
As the Internet evolves, the reduction of page load time has an increased importance. Additionally, the application layer is an ideal place to change as it avoids altering existing implementations. HTTP was designed not realizing what the Internet would look like at the present, and is thus outdated. Google has developed a protocol as a replacement for HTTP called SPDY. The major improvements are header compression to avoid network congestion, multiplexing to maximize throughput, and allowing the server to suggest or even push unsolicited data. My research aims to measure throughput of the two protocols by varying both the latency …
