    • Construction of a Low-Speed Closed-Return Wind Tunnel 

      Durbin, Jonathan (Houghton College, 2019-05-11)
      A small-scale, low-speed, closed-return wind tunnel is being designed and constructed at Houghton College to provide opportunities for further education and new research. Empirical correlations were used by previous ...
    • The Creation of Low Activity Mössbauer Sources for Undergraduate Research 

      Gula, August (Houghton College, 2016-05-05)
      An experimental test of general relativity can be made using the transverse Doppler effect. The design of the experiment conducted at Houghton College has entailed the development of low activity Mössbauer sources. These ...
    • Cross Section Measurements for Quasielastic Neutron-Induced Deuteron Breakup 

      Koehler, Katrina (Houghton College, 2011-05-14)
      An experiment to measure the quasielastic d(n;np)n scattering cross sections at intermediate incident neutron energies, ranging up to 800 MeV, was conducted by a collaboration of researchers from Houghton College, MIT, the ...
    • A CT Scanner Using Coincidence Techniques 

      Finch, Victoria (Houghton College, 2014-05-19)
      A CT scanner has been designed which uses gamma rays produced by positron annihilation. A low-activity 22Na source produces the positrons, which, when they annihilate, create 0.511 MeV gamma rays travelling in opposite ...
    • The Decay Rate of Orthopositronium 

      Winter, Blake (Houghton College, 2005-05-09)
      Until recently, measurements of the orthopositronium decay rate disagreed with the value predicted by quantum electrodynamics. This paper describes a novel attempt to measure this decay rate. Positrons from the decay of ...
