    • Three-dimensional simulation of coherent inverse Compton scattering 

      Resta, Giacomo Rosario (Massachusetts Institute of Technology, 2014)
      Novel compact X-ray sources using coherent ICS have the potential to positively impact a wide range of sectors by making hard x-ray techniques more accessible. However, the analysis of such novel sources requires improvements ...
    • A time domain phonon pulse fitting analysis for the cryogenic dark matter search experiment 

      Schlupf, Chandler (Massachusetts Institute of Technology, 2014)
      Dark matter makes up 85% of the known matter in the Universe, but the exact nature of dark matter remains unknown. The Cryogenic Dark Matter Search experiment, CDMS, attempts to directly detect the leading candidate dark ...
    • Total-to-peak ratios of high purity germanium gamma ray detector 

      Nelson, Justin Matthew, 1981- (Massachusetts Institute of Technology, 2004)
      This study is concerned with the percentage of [gamma]-rays of a certain energy having their energy correctly measured by a high purity Germanium [gamma]-ray detector. The ratio between the total counts and the counts ...
    • Towards a cryogenic planar ion trap for Sr-88 

      Bakr, Waseem (Waseem S.) (Massachusetts Institute of Technology, 2006)
      This thesis describes experiments with ion traps constructed with electrodes in a single two-dimensional plane, and ion traps operated in a cryogenic environment at 77K and 4K temperatures. These two technologies address ...
    • Towards a quantum gas microscope for fermionic atoms 

      Ramasesh, Vinay (Vinay V.) (Massachusetts Institute of Technology, 2012)
      This thesis reports the achievement of a two-species apparatus for use in an upcoming experiment with fermionic ultracold atomic gases. First, we describe the construction of a laser system capable of cooling and trapping ...
    • Towards detecting gravitational waves from the Crab Pulsar 

      Rapoport, Sharon, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
      A variety of fundamental and technical noise sources impact the ability of the Laser Interferometer Gravitational-Wave Observatory (LIGO) to directly detect gravitational radiation. Noteworthy examples include Newtonian ...
    • Towards qubit noise spectroscopy by quantum bang-bang control 

      Chen, Zilong, 1981- (Massachusetts Institute of Technology, 2004)
      Quantum bang-bang control is a method of suppressing decoherence in qubits [VKL99, VL98]. To date, mathematically rigorous treatments of quantum bang-bang control offered little intuition. To complement existing approaches ...
    • Towards the fabrication of suspended superconductor-graphene-superconductor Josephson junctions 

      Wei, Haofei (Massachusetts Institute of Technology, 2011)
      Graphene, a newly discovered material. has been the subject of much experimental and theoretical study due to its unique electronic behavior. In this thesis, I present, my work with graduate student Joel Wang to design and ...
    • Transport in chaotic magnetic fields 

      Holguin, Francisco, Jr (Massachusetts Institute of Technology, 2016)
      Many astrophysical environments are thought to contain force-free magnetic fields. The sine field is an example of a force-free, helical magnetic field, whose field lines are chaotic over the entire space. In this thesis, ...
    • Transport studies on CVD-grown graphene 

      Huntley, Miriam Hanna (Massachusetts Institute of Technology, 2009)
      In this thesis, we report transport studies performed on CVD-grown graphene. We perform resistivity and hall measurements on a large-area sample at 4' K. We measure the carrier mobility of the sample and find it to be on ...
    • Trapping cold rubidium in a fiber 

      Brown, David Ross, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2007)
      In this thesis, we demonstrate the novel technique of loading cold ⁸⁷Rb into a red-detuned optical dipole trap within a hollow core photonic fiber. This confines the atoms to 6 microns in two dimensions. We initially cooled ...
    • The trial of the holographic principle 

      Musiał, Wojciech, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2013)
      We present an introduction to ideas related to the holographic principle in the context of the well-established duality between classical gravity and conformal fluid dynamics. Foundations of relativistic hydrodynamics, ...
    • Tunneling density of states behavior in superconducting niobium-titanium.

    • Ultraviolet laser calibration of drift chambers 

      Elliott, Grant (Grant Andrew) (Massachusetts Institute of Technology, 2006)
