BC.00001: Overview of the Compact Toroidal Hybrid Experiment G.J. Hartwell, R.F. Kelly, S.F. Knowlton, C. Montgomery, J.T. Peterson, B.A. Stevenson The Compact Toroidal Hybrid (CTH) is a device used to study the physics of magnetically confined fusion energy related plasmas. CTH is a five-field period, low aspect ratio (R/a $\ge $ 3.5) torsatron that has a continuously-wound helical coil and a toroidal field coil set that allows the base vacuum rotational transform to be varied. The device parameters are R = 0.75 m, a$_{vessel}$ = 0.29 m, a$_{plasma }<$ .2 m, B $\le $ 0.6 T. Equilibrium, shaping, and ohmic current drive are provided by four independent poloidal field coil sets. The CTH missions are to use ohmic current to investigate current-driven ideal and resistive instabilities and disruptions in stellarators, and to test new 3-D equilibrium reconstruction procedures for helical confinement devices. Following vacuum field mapping studies, second harmonic electron cyclotron heating at 18 GHz will be pursued using an initial diagnostic set including probes, H$_{\alpha }$ monitors, and a microwave interferometer. Ohmic operation with equilibrium reconstruction will be implemented subsequent to these studies. An overview of the CTH project will be presented that will include the status of the CTH experiment and plans for the near future. [Preview Abstract] |

BC.00002: One-g Data of an Acoustic Fire Extinguishing Experiment Elizabeth Nelson, Dmitriy Plaks, Nesha Hyatt, Zade Coley, James Espinosa We are studying the effects of acoustics on a flame in microgravity. Our research is meant to provide a new approach to reducing and extinguishing a combustion reaction in space (where a conventional fire extinguisher is hazardous). Our setup includes an interior cage, inside of which is a candle; three speakers surround the cage, which are used to manipulate the flame. A video camera, infrared camera, temperature sensors, and microphone are placed in various locations throughout the setup to collect data. The master computer records all data and is later used for data analysis. We will describe the experimental apparatus in more detail, which will be flown aboard a NASA C-9B Aircraft. We will show 1g data collected with the apparatus and briefly describe NASA's Reduced Gravity Student Flight Opportunities Program (RGSFOP). [Preview Abstract] |

BC.00003: Einstein's Tests of General Relativity Through the Eyes of Newton Gary Hunter, James Espinosa, Julie Talbot Einstein suggested three possible tests of his Theory of General Relativity: 1) bending of starlight by the Sun, 2) precession of Mercury's orbit, and 3) gravitational redshift of spectra. Experimental and observational results of these tests are in excellent agreement with GR. We reinterpret these experiments and observations completely within the framework of Newtonian physics. We formulate a law of gravity that assumes this force travels at the speed of light and, when combined with Newton's second law, arrive at results identical to those of Einstein's theory. The steps leading to an analytical expression will be discussed. [Preview Abstract] |

BC.00004: Three Generations of Leptonic Mass and Half-life Averaging Benny Soldano Based on an electron half-life of 2.56 x 10$^{30}$ yrs, the gravitational implications of cube root averaging are examined. The half-life average is easily related to both the neutron's beta asymmetry decay constant as well as its phase space factor. The mass average gravitational accounts for (B$^{0}$ -- B$^{0 })$ and (B$^{\ast }$- B$^{0 })$. The link to gravitation arises from the experimental intervention of three additional spatial, string dimensions into our local brane at a four force uniting energy [2.961 Tev] with a Newtonian 1/r$^{2}$ limiting range R=0.7948 x 10$^{-8}$ cm; the latter when combined with the (SB) radiation constant at 273.14K creates a universal (i.e., charge quantization) leptonic mass to time average luminosity. When it is combined with the strong q / e$^{ }$\={ } ratio and the earth-sun gravitational packing fractions, the result matches both Dehmelt's geonium minimum and enlarges cube root averaging to include the earth-sun, one way gravitational transmission times.

BC.00005: Application of a Semiclassical Model for Particle Decay Eugene Chaffin, Nathan Hawkins We apply a tunneling model of particle decay via the intermediate vector boson. Past workers have applied the tunneling model to pair production [Schwinger, 1951; Brezin and Itzykson, 1970; Casher, Neuberger, and Nussinov, 1979]. In our model we apply a potential barrier of 80 GeV, the mass-energy of the W particle, to inhibit beta-decay. A factor similar to the Bethe preformation factor is then evaluated for various weak interaction particle decays to examine whether we get quantitative agreement with experiment. The model is successful in explaining why certain decays proceed by the strong interaction, and seems to simulate certain weak-decay ratios. [Preview Abstract] |

BC.00006: Generalization of the Klein-Gordon-Dirac expression for particles D.T. Froedge This paper puts fourth the proposition that Klein-Gordon-Dirac wave equation is derivable from a more general expression, and the solutions of the more general expression illustrate known particle properties, including potentials and mass ratios. The particle solutions of the general expression encompass the particles general properties as well as the electromagnetic interaction with other particles in the system. A plausible derivation of the mass ratios for particles is shown to imply certain allowed internal modes, which allow separation of the general equation into periodic and non-periodic equations. The modes and mass ratios are shown for the leptons, the proton, the neutron and the W boson. [Preview Abstract] |

BC.00007: What is a Particle in Classical Physics? A Wave? Ronald E. Mickens The concepts of ``particle" and ``wave" play important roles in quantum mechanics in that a given microscopic system can, under the proper circumstances, display properties of each.\footnote{A Messiah, Quantum Mechanics, Vols. I and II (Wiley, 1961).} However, these categories have their genesis in classical mechanics\footnote{H. Goldstein, Classical Mechanics (Addison-Wesley, 1980, 2nd edition).} and we must turn to this area to understand what they mean. In particular, it must be clearly understood that these concepts are idealistic representations of physical phenomena and, as a consequence, each may not correspond to any actual physical system. We discuss the definition of ``particle'' from the perspective of how it has been defined in standard textbooks and carry out a similar analysis for the notion of ``wave.'' We then define ``particle'' and ``wave'' within the context of classical mechanics by means of their respective equations of motion. The general (tentative) conclusion is that within the framework of classical mechanics the concepts of ``particle'' and ``wave'' systems may be unambiguously defined. [Preview Abstract] |

BC.00008: The Conservation of Lepton Number Russell Moon, Fabian Calvo, Victor Vasiliev In the vortex theory, it was proposed that all hadrons and the electron, muon, and tau leptons are three dimensional (3d) holes bent into and out of the surfaces of higher dimensional space [1]. These holes are the ends of vortices of space flowing through fourth dimensional space that originally connected them to their anti-particle. As space flows into a 3d hole, a positive electrostatic charge is created; as space flows out of a 3d hole a negative electrostatic charge is created; while neutral particles are vortices bent into torus configurations [2]. Neutrinos are quantized transverse waves bent out of the 3d surface and anti-neutrinos are bent into the 3d surface. Applying this model to the creation and destruction of leptons, a correlation was discovered between lepton number and the direction space is flowing (black arrows) in electrons, muons, taus, their anti-particles and, the direction bent space is oriented within their associated neutrino or anti-neutrino. \newline [1] R.G.Moon, V.V.Vasiliev, NUCLEUS-2003, 2003, Book of abstracts.

BC.00009: Unification of Massive Neutrinos of a Different Nature Rasulkhozha S. Sharafiddinov At the availability of a non - zero mass, the same neutrino regardless of whether it refers to Dirac or Majorana fermions, must possess simultaneously each of the anapole and electric dipole moments. Their interaction with field of emission can also lead to the longitudinal polarized neutrinos elastic scattering on a spinless nucleus. Using the process cross section, the united equation has been obtained between the anapole and electric dipole form factors of Dirac and Majorana neutrinos. It corresponds in the nature to the coexistence of neutrinos of both types. As a consequence, each of Dirac neutrinos testifies in favor of the existence of a kind of the Majorana neutrino. They constitute herewith the united families of massive neutrinos of a different nature. Therefore, any of earlier measured properties of neutrinos may serve as a certain indication to the existence simultaneously both of Dirac and of Majorana neutrinos. All findings are confirmed also by the comparatively new laboratory restrictions on these fermions self masses. Thereby they state that electromagnetic gauge invariance must have a new structure depending on nature of the inertial mass and saying that P - symmetry of a particle is basically violated at the expense of its rest mass.
