Characterization of mono-energetic charged-particle radiography for high energy density physics experiments
… alphas, has recently been used to image various High-Energy-Density Physics objects of interest, including Inertial Confinement Fusion capsules during their implosions, Laser-Plasma Interactions, and Rayleigh-Taylorinstability growth. An imploded D23He-filled glass capsule - the backlighter - …

Design and qualification of an absolute thickness measuring machine
… Livermore National Laboratory develops various high energy density physics targets, which are used to study the interaction of materials when shot with high energy lasers. These targets consist of many different types of materials glued together including low density foams, plastics, and metals. …

Proton acceleration experiment by high intensity laser pulse interaction with solid density target at the Texas Petawatt Laser Facility
In recent, high intensity laser pulse interaction with solid density matter has been studied in several laboratory and facilities. Multi-MeV proton and ion beams from plasma produced by this interaction is one important application research area of HEDP. In this thesis, the basic theory of hot …

A study of stimulated Brillouin scattering in laser produced plasmas
The production of high power, short duration laser pulses is of interest to a wide variety of applications ranging from high-energy-density physics to laser-driven nuclear fusion. The exploitation of laser-plasma instabilities, in particular stimulated Brillouin scattering (SBS), for the creation …

On The Origin of Super-Hot Electrons in Intense Laser-Plasma Interactions
… laser which resulted in the observation of the highest known positron energies ever recorded. The positrons are created by the Bethe-Heitler process where an electron scatters and emits bremsstrahlung radiation which then interacts with an atomic nucleus and creates an electron-positron pair. …

The Effect of Anomalous Resistivity on the Electrothermal Instability
… dependent, occurring in nearly all Z-pinch-like high energy density platforms. ETI growth for high-mass density materials is predominantly striation form which corresponds to magnetically perpendicular mode growth. The striation form is caused by a resistivity that increases with temperature, …

Magnetohydrodynamic Simulations of Fast Instability Development in Pulsed-Power--Driven Explosions and Implosions of Electrical Conductors
… that lead to degradations in fusion yield. High levels of azimuthally-correlated MHD instability structures have been observed on cylindrical liner experiments without a pre-imposed axial magnetic field (Bz=0) elsewhere in the literature and are believed to be seeded from surface machining …

Electronic structure of warm dense matter
… with compressions greater than four times solid density and temperatures of around 10 eV. This resulted in red-shifts of the K-edge energy on the order of 10 eV. Also measured are differences in the edge energy with increasing density between the two types of chlorine samples, demonstrating how …

Increased Proton Energies - Above the ~ 60 MeV Empirical Barrier, from High-Contrast High-Intensity Short-Pulse Laser-Interactions with Micro-Cone Targets
Ultra-high intensity lasers enable the investigation of extreme states of matter and the study of high energy density physics in the laboratory, as well as the creation of various intense radiation sources, i.e. electrons, X-rays, and ions. Of particular interest to this dissertation is the …
