An Investigation of Tungsten-Based Z-Pinch Planar Wire Array and Benchmarking Experiments
Wire array z-pinches provide an accessible means to research plasmas of high density and temperature and have valuable applications in the fields of inertial confinement fusion (ICF),astrophysics, and radiation studies. The purpose of this work is tungsten/aluminum z-pinch study and to aid in the …

Spectroscopic Measurements of Magnetic Field and Electron Density on Wire Array and Laser Plasmas
… laser plasmas and magnetized exploding wire array plasmas. We present spatially resolved magnetic field measurements from two different laboratory-produced plasmas using visible spectroscopy. We investigated the radial profiles of the magnetic field during the evolution of a plasma …

Development of a Single-Crystal X-ray Spectropolarimeter and Application to Wire-Array Z-pinches
… This instrument has been built and tested on wire array z-pinches. Since each x-ray emitting region potentially has a different polarization, the spectropolarimeter must be spatially resolved to obtain meaningful spectra. With the use of a collimating series of slits, the single-crystal x-ray …

Experimental Investigation of Sheared Flow Stabilization of Z-pinches
The wire array z-pinch is an efficient x-ray source [1] which has been proposed for use in indirect drive inertial confinement fusion schemes [2]. The z-pinch can become a more efficient x-ray source if its stability is improved. Cylindrical wire array z-pinch experiments where the Rayleigh-Taylor …

Theoretical and Experimental Studies of Radiation from Z-Pinch Complex Wire Arrays and Applications
… the process. The theoretical tools involve the Wire Ablation Dynamics Model (WADM) to infer z-pinch implosion characteristics and various non-local thermodynamic equilibrium (LTE) kinetic models to understand the radiative properties of plasmas, including a new model for L-shell Ag. The …

The Effect Of Stationary UV Excitation On The Optical Behavior Of Electrochemically Self-Assembled Semiconductor Nanowires
… optical response of the semiconductor quantum wire array when excited by stationary UV light. The array is synthesized by selectively electro-depositing the semiconductor material in electrochemically self-assembled porous alumina templates. Our studies are based on the optical behavioral …

Radiatively Cooled Magnetic Reconnection Experiments Driven by Pulsed Power
… Z (MARZ) experiments consist of a dual exploding wire array, driven by a 20 MA peak, 300ns rise time current generated by the Z pulsed-power machine (Sandia National Labs). The load generates oppositely-directed supersonic, super-Alfvénic, collisional plasma flows with anti-parallel magnetic …
