Magnetic flux reconstruction methods for shaped tokamaks
(Massachusetts Institute of Technology, 1994) -
A magnetic resonance approach to neurodegeneration
(Massachusetts Institute of Technology, 1997) -
Magnetic resonance imaging via radio frequency gradient with examples from NMR and pure NQR
(Massachusetts Institute of Technology, 1998)In this thesis, we explore the use of RF gradients in NMR imaging. RF gradients have advantages over gradients of the static magnetic field in that they are non-secular and offer more experimental freedom (for example they ... -
Mapping myocardial structure-function relations with cardiac diffusion and strain MRI
(Massachusetts Institute of Technology, 2002)The myocardial structure-function relation is the key to understand the functional design of the ventricular myocardium. While the function of myocardial fibers has been extensively studied, the recently observed laminar ... -
Maximizing nuclear power plant performance via mega-uprates and subsequent license renewal
(Massachusetts Institute of Technology, 2014)The goal of this thesis is to develop a methodology to evaluate the engineering and economic implications of maximizing performance of the United States' commercial fleet of nuclear power plants. This methodology addresses ... -
Measurement of the spin diffusion rate of dipolar order in single crystal calcium fluoride
(Massachusetts Institute of Technology, 2002)This thesis reports on the first measurement of the spin diffusion rate of a two-spin correlated state, known as dipolar order, in a single crystal of calcium fluoride. The experimental results for the component of the ... -
Measurements of divertor target plate conditions and their relationship to scrape-off layer transport
(Massachusetts Institute of Technology, 2019)Cross-field filamentary transport in the scrape-off layer (SOL) is important for controlling SOL profiles, main-chamber recycling fluxes, and divertor operation. However, questions remain about the extent to which divertor ... -
Measurements of injected impurity transport in text using multiply filtered soft x-ray detectors
(Massachusetts Institute of Technology, 1990) -
Mechanical and electromagnetic transverse load effects on superconducting niobium-tin performance
(Massachusetts Institute of Technology, 2009)Cable-in-Conduit Conductor is the typical geometry for the conductor employed in superconducting magnets for fusion applications. Once energized, the magnets produce an enormous electromagnetic force and very large transverse ... -
Mechanisms and limitations for water-cooling of high heat flux surfaces
