The coincident measurement of neutron-proton pairs from the photodisintegration of lithium-6
A 100 % duty cycle bremsstrahlung beam with a 67 Mev endpoint energy was used to produce neutron-proton coincidences from the photodisintegration of 6Li. The proton energy was measured with a 6E-E scintillator telescope; the neutron energy was determined by measuring its time of flight across two …

Coincident neutron/proton pairs from lithium-6 photodisintegration with 40-100 MeV photons
Bremsstrahlung photons with endpoint energies from 55 to 100 MeV were used to photodisintegrate $\sp6$Li nuclei, and emitted neutron/proton pairs were observed in coincidence. Measurement of the energies and angles of the emitted pair allowed reconstruction of the photon energy, as well as the …

Lithium-6 filter for a fission converter-based Boron Neutron Capture Therapy irradiation facility beam
… A storage system was designed to contain the lithium-6 filter safely when it is not in use. A mixed field dosimetry method was used to measure the photon, thermal neutron and fast neutron dose. The measured advantage depth is 9.3 ± 0.1cm without filter and 9.9 ± 0.1cm with 8mm lithium-6 …

Helium-3 elastic, inelastic, and charge-exchange scattering from lithium-6 at 24.6 and 27.0 MeV
A target consisting of 6Li evapOlrated OlntOl a carbon foil backing was bombarded with the 3He beam from the University of Illinois cyclotron. Solid state detectors in /\E - E' telescopes were used tc obtain energy spectra of the scattered 3He and of tritons from the charge exchange reaction. …

Evaluation of the Relative Neutronic Risk of Alternative Fusion Fuels
… Deuterium-Helium 3, Deuterium-Lithium 6, and Hydrogen-Boron 11. Simplistic shielding and activation models were carried out in standardized 500MW reactors.

Strongly-interacting fermions in an optical lattice
… the second focuses on the pairing of fermionic lithium-6 pairs in an optical lattice within the strongly interacting BEC-BCS regime. Common to both sets of studies is the use of a magnetically tunable Feshbach resonance to manipulate interactions between the atoms. In the first experiment, we …

Towards a quantum gas microscope for fermionic atoms
… system capable of cooling and trapping gaseous lithium-6 atoms in a 3D Magneto-Optical Trap. Second, we discuss the realization of a 2D Magneto-Optical Trap which, in our experiment, acts as a high-flux source of cold potassium-40 atoms. These two systems are critical first steps in cooling the …

Building an apparatus for ultracold lithium-potassium Fermi-Fermi mixtures
… and built laser systems to cool, trap and image lithium-6 and potassium-40 atoms. I also constructed the vacuum system for the experiment and experimentally tested a new method to coat the chamber with a Titanium-Zirconium- Vanadium alloy that acts as a pump. The final apparatus will use a 2D …

Detection of Antineutrinos at the North Anna Nuclear Generating Station
… CHANDLER detectors adopt a novel design using lithium-6 ($^6$Li) loaded zinc sulfide (ZnS) scintillator to tag neutron capture events, which significantly improves the IBD detection efficiency. The use of the Raghavan optical lattice brings enormous enhancement of light collection towards high …

Sp¨ate Annihilation wird also zu einer erhoehten Helium-3 und Lithium-6 Haeufigkeit im Vergleich zum Standardszenario fuehren. Als ein wichtiges Ergebnis meiner Arbeit habe ich auf Grund dieser Effekte Schranken sowohl an den …

Magnetically activated and guided isotope separation
… a scalable magnetic field gradient to enrich lithium-7 (Li-7) by suppressing lithium-6 (Li-6) throughput in a lithium atomic beam. We first evaporate lithium metal in a crucible in order to generate thermal, high flux beam. We then perform optical pumping on Li-6 atoms, magnetically polarizing …

Identification of battery products and intermediates through NMR spectroscopy
… of products and intermediates formed in the lithium-oxygen, lithium-sulfur, and lithium-ion battery systems. Interest in the species formed in cycled batteries is motivated by incomplete knowledge of the discharge mechanisms and products formed, where knowledge of these species can allow the …
