  • Salty development of an optical photoresist 
    Chao, Adam (Adam C.) (Massachusetts Institute of Technology, 2008)
    In this series of experiments, we add salt to a photoresist developer and observe the effect on photoresist contrast. In order to measure contrast, we designed an anti-reflection coating stack to reduce reflections between ...
  • Scanning tunneling spectroscopy of lead-substituted bismuth strontium copper oxide 
    Zimmermann, Michelle (Michelle Anne) (Massachusetts Institute of Technology, 2007)
    The hole-doped cuprate Bi ... is doped with lead to the solubility limit of x = 0.38 and studied using STM/STS in the overdoped regime where Tc < 2K. Despite the high lead content, residual supermodulations are observed ...
  • Scattering and mesons 
    Ramazanoğlu, Fethï Mübïn (Massachusetts Institute of Technology, 2006)
    We present the P-matrix, an alternative method to parameterize the S-matrix, which is particularly useful for low energy meson-meson scattering. We discuss its basic properties and use it to analyze the isospin 0 and 2 ...
  • The scattering and shrinking of a Gaussian wave packet by delta function potentials 
    Sun, Fei, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2012)
    In this thesis, we wish to test the hypothesis that scattering by a random potential causes localization of wave functions, and that this localization is governed by the Born postulate of quantum mechanics. We begin with ...
  • Scattering properties of polyacrylamide gels and their relation to protein electrophoretic migration 
    Cook, Laurel A. (Laurel Anne) (Massachusetts Institute of Technology, 1994)
  • Search for pre-existing Delta states at BLAST from ²H(e,e'[Delta]⁺⁺ 
    Greene Chana M. (Chana Michelle) (Massachusetts Institute of Technology, 2006)
    At the MIT-Bates Linear Accelerator Center a comprehensive study of low-Q2 spin-dependent electron scattering from deuterium has been carried out using the Bates Large Acceptance Spectrometer Toroid (BLAST). This experiment ...
  • Search for rare events in [the square root of sigma nu nu] = 200 GeV Au+Au PHOBOS data 
    Mott, Alexander (Alexander Robert) (Massachusetts Institute of Technology, 2009)
    In this analysis, we set an upper bound on the rate of rare events: events whose dN/dn distribution deviates more than statistically from the ensemble average dN/dn distribution for s [the square root of sigma nu nu] = 200 ...
  • Second order critical point in QCD phase diagram 
    Assawasunthonnet, Wathid (Massachusetts Institute of Technology, 2009)
    In this thesis I explore the theoretical model based on Asakawa and Nonaka's idea[l]. I start by arguing that the critical point of the QCD phase diagram is second order and belongs to the three dimensional Ising model ...
  • Self-adjoint extensions to the Dirac Coulomb Hamiltonian 
    Brainerd, Andrew Eric (Massachusetts Institute of Technology, 2010)
    The Dirac equation is the relativistic generalization of the Schrödinger equation for spin 1/2 particles. It is written in the form -ihc -ihac OXIa+t' Omc 29 = ih-o (1.1) where V) is a four component Dirac spinor and the ...
  • Self-assembly of conformal polymer electrolyte film for lithium ion microbatteries 
    Bieber, Christalee (Massachusetts Institute of Technology, 2007)
    I apply the theory of polar and apolar intermolecular interactions to predict the behavior of combinations of common battery materials, specifically the cathode substrate lithium cobalt oxide (LCO) and the polymer separator ...
  • A self-triggered readout for a time projection chamber 
    Werner, Andrew Thompson, 1981- (Massachusetts Institute of Technology, 2004)
    A self-triggering readout for a time projection chamber (TPC) is presented, with applications to novel forms of data acquisition for high energy physics application. The construction and initial testing of the readout ...
  • Shuttling of ions for characterization of a microfabricated ion trap 
    Fisher, Zachary (Zachary Kenneth) (Massachusetts Institute of Technology, 2012)
    In this thesis, I present experimental results demonstrating the characterization of a planar Paul trap. I discuss the theory of ion trapping and analyze the voltages required for shuttling. Next, the characteristics of a ...
  • Signal variation in single particle aerosol mass spectrometry 
    Wissner-Gross, Zachary Daniel (Massachusetts Institute of Technology, 2007)
    Rapid and accurate detection of airborne micro-particles is currently an important problem in national security. One approach to such detection, bioaerosol mass spectrometry (BAMS), is currently under development at Lawrence ...
  • Simulated liquid argon interactions with neutrons 
    Harrington, Kathleen M (Massachusetts Institute of Technology, 2012)
    The GEANT4 physics simulation program is known to have errors in how hadronic interactions are implemented. This has the potential to cause errors in the Monte Carlos used to determine the expected neutron backgrounds in ...
  • Simulated pion photoproduction experiments 
    Howe, Ethan (Ethan Gabriel Grief) (Massachusetts Institute of Technology, 2005)
    Introduction: In this paper, I will be assessing the capabilities of the Neutral Meson Spectrometer (NMS) detector in a planned experiment at the High Intensity Gamma Source at Duke University. I will review the relevant ...
  • Simulating scanning tunneling microscope measurements 
    Venkatachalam, Vivek (Massachusetts Institute of Technology, 2006)
    One of the largest problems in scanning tunneling microscopy design is noise control. It is the burden of the designer to determine if money should be used to build a floating room for vibration isolation or for top-of-the-line ...
  • Simulation of a pion photodetection experiment 
    Solis Ortíz, Angel Roberto (Massachusetts Institute of Technology, 2006)
    In this thesis we asses the capabilities of the Crystal Box detector and evaluate its advantages over the Neutral Meson Spectrometer (NMS) detector in a planned experiment at the High Intensity Gamma Source (HI[gamma]S) ...
