Making Artificial Cips Data With A Generative Adversarial Neural Network, Austin Hedges

Fall Showcase for Research and Creative Inquiry

Polar mesospheric clouds (PMCs) have been studied for thirteen years by NASA's Aeronomy of Ice in the Mesosphere (AIM) satellite. The Cloud Imaging and Particle Size (CIPS) instrument onboard AIM has taken many images of PMCs over this time. Such a large number of images makes CIPS data ideal for training neural networks which require large datasets. CIPS images were used to train a Generative Adversarial Network (GAN) to train towards being able to generate purely artificial CIPS-like images.

Physics 223: Statistical Mechanics And Dice, Connor Rosenberry

2020 Virtual Spring Student Showcase for Research and Creative Inquiry

In this experiment, we will study the properties of entropy, multiplicity and probability using dice. We will roll 4 & 8 sided dice together and 4, 6, and 8 sided dice together for many trials and we will record the sum of the dice for each roll. We will then calculate each possible outcome’s expected multiplicity and probability of occurring. We can also predict each outcome’s expected entropy and compare these expected values of multiplicity and entropy to their actual values we found in this experiment. In doing so, we will be able to see the natural tendency of systems …

Physics 223 Poster: Hubble Law, Rebecca Alvarez

2020 Virtual Spring Student Showcase for Research and Creative Inquiry

In this experiment, we analyzed the images and spectra of multiple galaxies and found the velocity and distance from Earth of each galaxy. Plotting the velocity against distance, we found a value for the Hubble constant using the slope of the trendline. This value was used to compute the age of the universe. Both the Hubble constant and the age of the universe were compared to the currently accepted values for consistency.

Effects Of Electric And Magnetic Fields On Moving Liquid Paint On A Glass Surface, John J. Blalock

Theses & Honors Papers

A Tesla coil is a special type of step-up transformer. It takes an input current at a given frequency and voltage, increases the frequency and voltage via resonant induc­ tive coupling, and outputs a very high frequency, high voltage current . While it was originally intended as a means of wirelessly transferring energy, the output from a Tesla coil been used in the arts to move paint around on a glass surface using extremely high voltages on the order of 1 megavolt (MV) or 1000000 volts (V). The aim of this project was to scientifically determine what these mechanisms are …

Measurement Of The Neutron Radius Of (208)Pb Through Parity Violation In Electron Scattering, S. Abrahamyan, Timothy Holmstrom, Prex Collaboration

Chemistry & Physics Faculty Publications

We report the first measurement of the parity-violating asymmetry A_PV in the elastic scattering of polarized electrons from ²⁰⁸Pb. A_PV is sensitive to the radius of the neutron distribution (R_n). The result A_PV=0.656±0.060(stat)±0.014(syst)  ppm corresponds to a difference between the radii of the neutron and proton distributions R_n-R_p=0.33_-0.18^+0.16  fm and provides the first electroweak observation of the neutron skin which is expected in a heavy, neutron-rich nucleus.

New Precision Limit On The Strange Vector Form Factors Of The Proton, Z. Ahmed, Timothy Holmstrom, Happex Collaboration

Chemistry & Physics Faculty Publications

The parity-violating cross-section asymmetry in the elastic scattering of polarized electrons from unpolarized protons has been measured at a four-momentum transfer squared Q²=0.624  GeV² and beam energy E_b=3.48  GeV to be A_PV=-23.80±0.78(stat)±0.36(syst) parts per million. This result is consistent with zero contribution of strange quarks to the combination of electric and magnetic form factors G_E^s+0.517G_M^s=0.003±0.010(stat)±0.004(syst)±0.009(ff), where the third error is due to the limits of precision on the electromagnetic form factors and radiative corrections. With this measurement, the world data on strange contributions to nucleon form factors …

Beam-Target Double-Spin Asymmetry A(Lt) In Charged Pion Production From Deep Inelastic Scattering On A Transversely Polarized (3)He Target At 1.4, J. Huang, Timothy Holmstrom, Jefferson Lab Hall A Collaboration

Chemistry & Physics Faculty Publications

We report the first measurement of the double-spin asymmetry A_LT for charged pion electroproduction in semi-inclusive deep-inelastic electron scattering on a transversely polarized ³He target. The kinematics focused on the valence quark region, 0.1622. The corresponding neutron A_LT asymmetries were extracted from the measured ³He asymmetries and proton over ³He cross section ratios using the effective polarization approximation. These new data probe the transverse momentum dependent parton distribution function g_1T^q and therefore provide access to quark spin-orbit correlations. Our results indicate a positive azimuthal asymmetry for π^- production on ³He and …

Search For A New Gauge Boson In Electron-Nucleus Fixed-Target Scattering By The Apex Experiment, S. Abrahamyan, Timothy Holmstrom, Jefferson Lab

Chemistry & Physics Faculty Publications

We present a search at the Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling α^′ to electrons. Such a particle A^′ can be produced in electron-nucleus fixed-target scattering and then decay to an e⁺e^- pair, producing a narrow resonance in the QED trident spectrum. Using APEX test run data, we searched in the mass range 175–250 MeV, found no evidence for an A^′→e⁺e^- reaction, and set an upper limit of α^′/α≃10^-6. Our findings demonstrate that fixed-target searches can explore a new, …

Single Spin Asymmetries In Charged Pion Production From Semi-Inclusive Deep Inelastic Scattering On A Transversely Polarized (3)He Target At Q(2)=1.4–2.7  Gev(2), X. Qian, Timothy Holmstrom, Jefferson Lab Hall A Collaboration

Chemistry & Physics Faculty Publications

We report the first measurement of target single spin asymmetries in the semi-inclusive ³He(e,e^′π^±)X reaction on a transversely polarized target. The experiment, conducted at Jefferson Lab using a 5.9 GeV electron beam, covers a range of 0.1622. The Collins and Sivers moments were extracted from the azimuthal angular dependence of the measured asymmetries. The π^± Collins moments for ³He are consistent with zero, except for the π⁺ moment at x=0.35, which deviates from zero by 2.3σ. While the π^- Sivers moments are consistent with zero, the π⁺ Sivers moments favor …

Exclusive Neutral Pion Electroproduction In The Deeply Virtual Regime, E. Fuchey, Timothy Holmstrom, Jefferson Lab Hall A Collaboration

Chemistry & Physics Faculty Publications

We present measurements of the ep→epπ⁰ cross section extracted at two values of four-momentum transfer Q²=1.9 GeV² and Q²=2.3 GeV² at Jefferson Lab Hall A. The kinematic range allows one to study the evolution of the extracted cross section as a function of Q² and W. Results are confronted with Regge-inspired calculations and GPD predictions. An intepretation of our data within the framework of semi-inclusive deep inelastic scattering is also discussed.

Measurements Of The Electric Form Factor Of The Neutron Up To Q(2)=3.4 Gev2 Using The Reaction (3)(He)Over-Right-Arrowe((E)Over-Right-Arrow, E ' N)Pp, S. Riordan, Timothy Holmstrom

Chemistry & Physics Faculty Publications

The electric form factor of the neutron was determined from studies of the reaction ³He⃗(e⃗,e^′n)pp in quasielastic kinematics in Hall A at Jefferson Lab. Longitudinally polarized electrons were scattered off a polarized target in which the nuclear polarization was oriented perpendicular to the momentum transfer. The scattered electrons were detected in a magnetic spectrometer in coincidence with neutrons that were registered in a large-solid-angle detector. More than doubling the Q² range over which it is known, we find G_Eⁿ=0.0236±0.0017(stat)±0.0026(syst), 0.0208±0.0024±0.0019, and 0.0147±0.0020±0.0014 for Q²=1.72, 2.48, and 3.41  GeV², respectively.

Environmental Analysis Of Toxic Metals Produced By Cigarette Smoking, Catherine H. Swandby, Melissa C. Rhoten, Joseph E. Garcia

Theses & Honors Papers

Trace metal elements introduced into our environment from anthropogenic sources can become toxic at high levels contributing to a host of human and animal health problems. The purpose of this work is to initially characterize toxic metals present in cigarette tobacco and ash using Electrothermal Atomic Absorption Spectroscopy (ETAAS). The broader impact of this study is to assess the environmental effects of cigarette smoking around designated smoking areas on the Longwood University campus. Smokers may not be informed about the potential harm to the environment from "ashing" directly on the ground. If the toxic metals present in cigarette ash are …
