Theoretical and Experimental Studies of Radiation from Z-Pinch Complex Wire Arrays and Applications
… on the 1.7 MA Zebra generator at the Nevada Terawatt Facility (NTF) at the University of Nevada, Reno (UNR). Traditional nested cylindrical wire arrays with mixed materials (brass and Al, Mo and Al) were tested to understand how the inner and outer arrays implode and radiate. Novel planar …

Annealing for intrinsic point-defect control and enhanced solar cell performance : the case of H₂S and tin sulfide (SnS)
… as the PV industry grows toward the terawatt level. Growth of SnS is explored using RF sputtering and thermal evaporation. Thermal evaporation yielded phase pure films and a SnS solar cell device stack was developed using a ZnOxSy film as the n-type buffer layer. It is hypothesized …

Developing cuprous oxide thin film characterization techniques to illuminate efficiency-limiting mechanisms in photovoltaic applications
… whose resource bases cannot satisfy global, terawatt-level penetration. This necessitates the development of cheap, earth-abundant semiconductors for solar conversion such as cuprous oxide (Cu₂O). Poor solar energy conversion efficiency (<2%) has hindered the development of this material, yet …

An Investigation of Tungsten-Based Z-Pinch Planar Wire Array and Benchmarking Experiments
… Nevada, Reno (UNR) Physics Department's Nevada Terawatt Facility (NTF), which creates plasmas with typical radiationemission quantum energies up to 2 MeV. This radiation is studied using an extensive suite of diagnostics, including optical imaging systems, x-ray detectors, spectrometers, and …

Legal consideratios in developing and implementing the 2018 draft intergrated resources plan (IRP): a case study of the nuclear sector
… energy demand downwards from a projection of 525 Terawatt hours (TWh) of power in 2050 to 430 TWh for the most optimistic ‘high’ scenario. This revision is the main reason the new IRP no longer calls for massive new coal plants and has relegated nuclear to specific scenarios instead of the ‘base …

Electron Hydrodynamics in Crystalline Solids: Microscopic Origins, Mesoscopic Size Effects, and Macroscopic Observables
… With data centres already using an estimated 200 terawatt hours each year, and projected to make up as high as 8% of global demand by 2030, there is a pressing need to design energy-efficient nanoelectronics using bottom-up techniques. As high-quality single-crystal materials used in …

Theoretical and Experimental Studies of Radiation from High-Z Multiply Ionized L-shell Ions with Emphasis on X-ray Line Polarization
… experimental data are produced on the Nevada Terawatt Facility (NTF) Zebra generator at the University of Nevada, Reno. Spectroscopic analysis reveals the existence of two distinct plasma radiation sources, one which originates from the cross point and produces electron temperatures as high as …

Shock Waves in Gas and Plasma in Strong Magnetic Fields
… before. Experiments were performed at the Nevada Terawatt Facility(NTF). The platform uses the approximately 30 J, 0.35 ps-0.8 ns, 1056 nm Leopard laser focused onto 1-2.5 mm Cu rod loads positioned inside the Zebra pulsed-power vacuum chamber. A plasma piston produced by laser ablation drives a …

Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design
Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons …
