All-optical method of nanoscale magnetometry for ensembles of nitrogen-vacancy defects in diamond
(Massachusetts Institute of Technology, 2015)
The Nitrogen-Vacancy (NV) defect in diamond has shown considerable promise in the field of small scale magnetometry due to its high localization and retention of favorable optical properties at ambient conditions. Current ...
Separate effects of surface roughness, wettability and porosity on boiling heat transfer and critical heat flux and optimization of boiling surfaces
(Massachusetts Institute of Technology, 2012)
The separate effects of surface wettability, porosity, and roughness on critical heat flux (CHF) and heat transfer coefficient (HTC) were examined using carefully-engineered surfaces. All test surfaces were prepared on ...
Thermal analysis of uranium zirconium hydride fuel using a lead-bismuth gap at LWR operating temperatures
(Massachusetts Institute of Technology, 2012)
Next generation nuclear technology calls for more advanced fuels to maximize the effectiveness of new designs. A fuel currently being studied for use in advanced light water reactors (LWRs) is uranium zirconium hydride ...
CRUD resistant fuel cladding materials
(Massachusetts Institute of Technology, 2013)
CRUD is a term commonly used to describe deposited corrosion products that form on the surface of fuel cladding rods during the operation of Pressurized Water Reactors (PWR). CRUD has deleterious effects on reactor operation ...
Tritium production analysis and management strategies for a Fluoride-salt-cooled high-temperature test reactor (FHTR)
(Massachusetts Institute of Technology, 2013)
The Fluoride-salt-cooled High-temperature Test Reactor (FHTR) is a test reactor concept that aims to demonstrate the neutronics, thermal-hydraulics, materials, tritium management, and to address other reactor operational ...
Design of the gas-puff imaging diagnostic for Wendelstein 7-X
(Massachusetts Institute of Technology, 2019)
Stellarators, being not as well-studied as tokamaks, have plenty of interesting physics to examine, as investigations of stellarators as a viable configuration for future power plants continue. One of these aspects is ...
First-principles study of the surfaces of zirconium during early stages of metal oxidation
(Massachusetts Institute of Technology, 2015)
The surfaces of zirconium during early stages of metal oxidation were examined by first-principles calculations using density functional theory. DFT calculations suggested that the interaction between the oxide and the ...
An assessment of North Korea's nuclear weapons capabilities
(Massachusetts Institute of Technology, 2013)
In February of 2013, North Korea conducted its third nuclear weapons test. Speculations are that this test was conducted to further develop a warhead small enough to fit on an intercontinental ballistic missile. This test ...
Developments and benchmarking applications for Grasshopper : a Geant4 based physics simulation tool
(Massachusetts Institute of Technology, 2020)
Current particle physics simulations take place largely within small communities developing limited tools for specific areas of study. These particle simulations are essential to evaluating environments outside of the realm ...
Construction of a model for the improved planning of MCO-informed VMAT in RayStation using a knowledge base of clinical IMRT-MCO treatment plans
(Massachusetts Institute of Technology, 2017)
Intensity Modulated Radiation Therapy (IMRT) is a type of external beam radiation therapy that has proven effective at treating many cancers. A related therapy type, Volumetric Modulated Arc Therapy (VMAT), has the potential ...
