C3.00001: SPS Evening of Undergraduate Science Invited Speaker: James Merrick The Society of Physics Students (SPS) invites all undergraduates and their mentors attending the meeting to participate in an informational talk on benefits and opportunities to joining the SPS community. This interactive dialogue will outline how SPS can help you become involved in the community (locally and nationally), conduct research and outreach, communicate on a national scale, and take advantage of the resources available to you. Even if you've not done so yet, come learn how to make a big impact in your local department and the physics and astronomy community as a whole. [Preview Abstract] |

C3.00002: Superheroes Across the Electromagnetic Spectrum Invited Speaker: Stephanie Slater Superheroes have superpowers granted to them through the tremendous energies provided by the electromagnetic spectrum. Come argue about which wavelengths provide the best superpowers to save the world from evil. [Preview Abstract] |

C3.00003: Determining the Shape of Glowing Objects: Applications to Supernovae Zakary Noel, Suzanne Wheeler, Gabrianna Escamilla, Daniel Dove, Cristian Bahrim Our experiment aims to provide a methodology for determining the shape of a glowing object using polarimetric measurements. We propose a simple, but reliable, tabletop setup, which includes a polarizer/analyzer pair for light analysis located between a black-body emitter and a light sensor. Polygon shaped apertures are mounted in front of a glowing cavity in order to choose a probe signal which characterizes the shape of a glowing object. We have determined that a comparison between the experimental ratios of normalized probe signals to control (circular) signals based on area coverage of the polygon can lead to the identification of the aperture's shape. The overall perceived intensity of the detected light depends on the sensitivity of the photo-detector; therefore, we plan to improve our well calibrated system by using filters in order to eliminate wavelengths of light that lie on the outskirts of the detection range for our light sensor. In addition, we discuss the merits of performing the experiment in a gaseous environment that simulates the atmospheric conditions present on Earth, such as our nitrogen-rich environment.

C3.00004: Synthesis and properties of new U3TiSb5-type compounds Maegan Idrogo, Daniel Jackson, Derrick VanGennep, James Hamlin Recently it was found that single crystals of Ce3TiSb5 exhibit a complex temperature/magnetic-field phase diagram with several metamagnetic transitions and a possible re-entrant disordered phase. In this presentation I will discuss our efforts to synthesis and characterize other members of the “3-1-5” family of compounds. In particular, we synthesized single crystal of both Ce3ZrSb5 and Pr3TiSb5 using Sn flux growths. We find that Pr3TiSb5 exhibits similar magnetic transitions at high field as Ce3TiSb5.

C3.00005: Measuring Q-Values and Elastic Nuclear Scattering Cross Sections for Protons on Lithium Fluoride Kassie Marble, James Florence, Daniel Marble Elastically scattered protons and nuclear reaction products have been measured for MeV energy protons incident upon thick Lithium Fluoride targets. Spectra for protons on lithium fluoride show three separate interaction mechanisms: Rutherford scattering, nuclear elastic scattering, and nuclear reactions. Modeling of the elastic scattering portion of the spectra with RUMP for protons incident upon lithium fluoride supports incident beam energy of 1.29 MeV but, the ratio of the lithium to fluorine yields from the elastic scattering portion of the spectra deviates from the Rutherford Z$^{\mathrm{2}}$ dependence indicating the presence of elastic nuclear scattering. In addition to nuclear scattering effects, the spectra also showed multiple peaks with energies greater than the incident ion beam energy due to nuclear reactions. Using these high energy peaks, Q-values are obtained that are within 7{\%} of accepted values for the $^{\mathrm{6}}$Li (p,$^{\mathrm{3}}$He) $^{\mathrm{4}}$He reaction, the $^{\mathrm{7}}$Li (p,$^{\mathrm{4}}$He) $^{\mathrm{4}}$He reaction, and the $^{\mathrm{19}}$F (p,$^{\mathrm{4}}$He) $^{\mathrm{16}}$O nuclear reaction. A discussion of our experimental results will be presented along with our work to improve measurements of elastic nuclear scattering cross sections as a function of incident energy for protons on lithium by using special enriched ultra-thin lithium targets deposited on a thin-layer of gold on carbon combined with Rutherford scattering of helium on lithium.

C3.00006: Research paper on "dye doped nematic liquids used in detecting gravitational wave in less sophisticated method" Lasin Abdurahiman, Muhammad Sajeer p In the present work, non linear properties of liquid crystal is applied to detect and study Gravitational waves in LIGO, even with the use of much sophisticated devices like Seismic isolator and Vacuum tubes, complete vacuum could not be attained. We hereby propose an alternative method usingDye doped Nematic liquid crystals to produce electro magnetic soliton which maintains it s amplitude and energy without any lose. When Gravitational waves are passing through the crystals, there would be small change in the orientation of the crystal causing chaotic changesin the refractive index these changes indicates the presence of Gravitational waves.

C3.00007: Wireless Data Transmission Colton Watson, Josh Mclain, Braylon Johnson, Edgar Garcia, Rodrigo Sanchez A series of different tests will be applied to the product that will revolve around the satisfaction of the client. A transmission test will assure the capabilities of the Xbee Pro 900 XSC S3B and its ability to transmit data wirelessly. The team will become familiar with the software that is needed to program the system. Software familiarization will allow for communication between the transmitter and receiver, which is vital for this testing phase. Different size text files will be sent between the two modules to analyze the quickness of the process and their range of transmission. [Preview Abstract] |
