    • Magnetically torqued thin accretion disks 

      Savcheva, Antonia Stefanova (Massachusetts Institute of Technology, 2006)
      We consider geometrically thin accretion disks around millisecond X-ray pulsars. We start with the Shakura-Sunyaev thin disk model as a basis and modify the disk equations with a magnetic torque from the central neutron ...
    • Mapping bulk electrical properties with non-contact RF measurements 

      Schwartz, Benjamin M. (Benjamin Matthew) (Massachusetts Institute of Technology, 2006)
      The human body is composed primarily of dielectric tissue with spatially varying permittivity and conductivity. Traditional MRI does not measure these properties. Instead, the conductivity of the patient is a nuisance, ...
    • Mass ratios in stellar triple systems that admit horseshoe orbits 

      Balaji, Bhaskaran (Massachusetts Institute of Technology, 2016)
      We examine possible configurations of stellar triple systems that give rise to "horseshoe orbits" in the smallest body. Several configurations are tested according to the initial parameters of mass for each of three bodies ...
    • Massive stable charged particle signatures in simulations at the LHC 

      Silva, James B. (James Brian) (Massachusetts Institute of Technology, 2008)
      The importance of heavy stable charged (HSCP) particles lies in the exploration of extensions to the standard model. Extensions of the standard model attempt to solve current problems in the standard model such as the ...
    • Measurement of plasma flows using Mach probe arrays 

      Kardon, Brian (Brian Michael) (Massachusetts Institute of Technology, 2008)
      A rectangular array of three-dimensional Mach probes is constructed and installed in the plasma vessel of the Versatile Toroidal Facility (VTF) at MIT in order to measure ion flow velocity on the cross section of the VTF. ...
    • Measurement of radio-frequency magnetic fluctuations in the VTF magnetic reconnection experiment 

      Whitney, John Peter, 1982- (Massachusetts Institute of Technology, 2004)
      In this thesis work, I designed, fabricated, and calibrated, a radio-frequency magnetic probe, subsequently used to measure magnetic turbulance in the reconnecting plasmas of the Versatile Toroidal Facility (VTF). Reconnecting ...
    • Measurement of the correlation spectrum of electrostatic potential fluctuations in a toroidal Helimak plasma 

      Zimmerman, Eric D. (Eric Daniel) (Massachusetts Institute of Technology, 1993)

      Rysewyk, Devyn Marie (Massachusetts Institute of Technology, 2015)
      Project 8 is an experiment that aims to determine the neutrino mass from a measurement of the endpoint of the tritium beta-decay continuous energy distribution. To do this, Project 8 is utilizing the cyclotron radiation ...
    • Measurement of the vortex depinning force in a high temperature superconductor 

      Whitehead, Andrew Patrick (Massachusetts Institute of Technology, 2005)
      Introduction: Superconductivity is one of those subjects in physics that is as captivating theoretically as it is experimentally interesting. The dual driving force of commercial demand for high-temperature superconductors ...
    • Measurement of work function in CF₄ gas 

      Wolfe, Ian C (Massachusetts Institute of Technology, 2010)
      CF4 gas is useful in many applications, especially as a drift gas in particle detection chambers. In order to make accurate measurements of incident particles the properties of the drift gas must be well understood. An ...
