2d Ion Temperature Maps From Twins Ena Data: Idl Scripts, Amy Keesee, Earl Scime, Anna Zaniewski, Roxanne Katus

Physics Scholarship

Energetic neutral atom (ENA) flux from the NASA TWINS mission (and previously the MENA instrument on the NASA IMAGE mission) is projected along the line of sight to the equatorial plane in GSM coordinates. A Maxwellian fit is used to calculate the ion temperature in each equatorial plane bin, creating 2D maps of ion temperatures. The files are IDL .pro scripts that can be read using a text editor. IDL software is required to run. The primary script is twins_master.pro. The scripts call other scripts that were developed by the TWINS mission team as well as publicly available IDL ...


3 - The Zeeman Effect And Its Potential In Molecular Spectroscopy, Megan L. Climer Nov 2018

3 - The Zeeman Effect And Its Potential In Molecular Spectroscopy, Megan L. Climer

Georgia Undergraduate Research Conference (GURC)

Zeeman Effect and Its Potential in Molecular Spectroscopy

Megan Climer

The Zeeman Effect is a splitting of energy levels or shells within an atom that is caused by an external magnetic field exerting torque on the electrons in the atom. The splitting itself is proportional to the strength of the magnetic field applied while the number of splits depends on the energy level of the atom itself. These splits can be observed in spectroscopy as distinct spectral lines that are formed in the place where only one was before. Studying this difference due to the magnetic field allows us to ...

Hygrothermal Performance Of Sealed Attics In Climate Zone 3a, Mikael Salonvaara, Achilles Karagiozis, William Miller Sep 2018

Hygrothermal Performance Of Sealed Attics In Climate Zone 3a, Mikael Salonvaara, Achilles Karagiozis, William Miller

International Building Physics Conference

Sealed attics with fiberglass have been in the US building codes for several codes cycles. Prior to the IRC 2018, air permeable insulation (such as fiberglass) was previously allowed to be deployed without continuous air impermeable insulation only in dry climate zones 2B and 3B in tile roofs systems. New research has revealed that asphalt shingles can also be allowed as implemented in the new IRC 2018 with a new addition to the section for sealed attics using air permeable insulations. The new building code also permits the use of air permeable insulation without air impermeable insulation in climate zones ...

Isotope Effect On Electron-Phonon Interaction In Multiband Superconductor Mgb2, Adam Kaminski, Daixiang Mou, Paul C. Canfield, Serguei Budko, Lunan Huang, Valentin Taufour, Yun Wu, Soham Manni Apr 2016

Isotope Effect On Electron-Phonon Interaction In Multiband Superconductor Mgb2, Adam Kaminski, Daixiang Mou, Paul C. Canfield, Serguei Budko, Lunan Huang, Valentin Taufour, Yun Wu, Soham Manni

Ames Laboratory Datasets

We investigate the effect of isotope substitution on electron-phonon interaction in multi-band superconductor MgB$_2$ using tunable laser based Angle Resolved Photoemission Spectroscopy. The kink structure around 70 meV in Sigma band, which is caused by electron coupling to E_2g phonon mode, is shifted to higher binding energy by ~3.5 meV in Mg^10B2. The changes of the kink energy reported here suggest that the anharmonicity of the E2g phonon in MgB2 is very small, which reopens the debate about the unusually small isotope coefficient in this material. These results are the benchmark for investigation of isotope effect in ...

Discovery Of Dirac Node Arcs In Ptsn4, Adam Kaminski, Paul C. Canfield, Serguei Bud'ko, Daixiang Mou, Eundeok Mun, Yun Wu, Lunan Huang, Yongbin Lee, Duane D. Johnson, Linlin Wang

Ames Laboratory Datasets

In topological quantum materials the conduction and valence bands are connected at points (Dirac/Weyl semimetals) or along lines (Line Node semimetals) in the momentum space. Numbers of studies demonstrated that several materials are indeed Dirac/Weyl semimetals. However, there is still no experimental confirmation of materials with line nodes, in which the Dirac nodes form closed loops in the momentum space. Here we report the discovery of a novel topological structure - Dirac node arcs - in the ultrahigh magnetoresistive material PtSn4 using laser-based angle-resolved photoemission spectroscopy (ARPES) data and density functional theory (DFT) calculations. Unlike the closed loops of line ...

Imaging The Magnetic Nano-Domains In Nd2fe14b, Adam Kaminski, Daixiang Mou, Paul C. Canfield, Valentin Taufour, Lunan Huang, Serguei Budko, Benjamin Schrunk, Tey Lamichhane Jan 2016

Imaging The Magnetic Nano-Domains In Nd2fe14b, Adam Kaminski, Daixiang Mou, Paul C. Canfield, Valentin Taufour, Lunan Huang, Serguei Budko, Benjamin Schrunk, Tey Lamichhane

Ames Laboratory Datasets

We study magnetic domains in Nd2Fe14B single crystals using high resolution magnetic force microscopy (MFM). Previous MFM studies and small angle neutron scattering experiments suggested the presence of nano-scale domains in addition to optically detected micrometer-scale ones. We find, in addition to the elongated, wavy nano-domains reported by a previous MFM study, that the micrometer size, star shape fractal pattern is constructed of an elongated network of nano-domains ~20 nm in width, with resolution-limited domain walls thinner than 2 nm. While the microscopic domains exhibit significant resilience to an external magnetic field, some of the nano domains are sensitive to ...

Selectivity Mechanism Of The Voltage-Gated Proton Channel, Hv1, Todor Dudev, Boris Musset, Deri Morgan, Susan M. Smith May 2015

Selectivity Mechanism Of The Voltage-Gated Proton Channel, Hv1, Todor Dudev, Boris Musset, Deri Morgan, Susan M. Smith

Faculty Publications

Abstract• Introduction• Results• Discussion• Methods• Additional Information• References• Acknowledgements• Author information• Supplementary information Voltage-gated proton channels, HV1, trigger bioluminescence in dinoflagellates, enable calcification in coccolithophores, and play multifarious roles in human health. Because the proton concentration is minuscule, exquisite selectivity for protons over other ions is critical to HV1 function. The selectivity of the open HV1 channel requires an aspartate near an arginine in the selectivity filter (SF), a narrow region that dictates proton selectivity, but the mechanism of proton selectivity is unknown. Here we use a reduced quantum model to elucidate how the Asp–Arg SF selects protons but ...
