Theory and Application of Thomson Scattering to Particle Transport and Magnetic Field Measurements in Laser-Produced Plasmas
DownloadSpring 2023
The particle transport, plasma currents, and magnetic fields were investigated in laboratory plasmas, both with the Optical Thomson Scattering (OTS) diagnostic and in theory and numerical simulations. %despite the presence of hot ion tails, which would be more suppressed by collisions in real...

Putative ante-mortem indicators of Alzheimer’s dementia: Analysis of fluid biomarker and neuroimaging studies
DownloadSpring 2019
Dementia is a clinical state, characterized by symptoms indicative of deterioration of memoryand cognitive functions that interferes with social or occupational functioning. According to2018 statistics, around 50 million people are living with dementia, and this number will increaseto 131.5...

Langmuir amplitude modulations and harmonic waves, generated by solar wind electron beams, are commonly observed in type III solar radio bursts. Various mechanisms have been proposed for the origin of these waves, but there is still ongoing debate on how the observation of continuous type III...

The effect of partial coherence of a probe on the spectrum of Thomson scattered radiation from plasma is investigated. The coherence of a probe is described in terms of the electric field Gaussian correlation function of the finite correlation time (longitudinal coherence) and the finite...

In this thesis we present Particle-in-Cell (PIC) plasma simulations designed to model large amplitude whistler waves. There are significant nonlinear effects that arise due wave-wave and wave-particle interactions. There are two related sections to this report: one investigating the evolution of...

On 23 November 2012, a sudden dropout of the relativistic electron flux was observed after an interplanetary shock arrival. The dropout peaks at ∼1 MeV and more than 80% of the electrons disappeared from the drift shell. Van Allen twin Probes observed a sharp electron flux dropout with clear...

Laser plasma interactions with high intensity laser pulses can produce extremely high magnetic fields in the MG range. In particular, the application of circularly polarized or orbital angular mode (OAM) laser beams can be used to generate such large fields using the Inverse Faraday Effect (IFE)....

Development of Liquid Chromatography Mass Spectrometry Methods for the Identification and Quantification of Acylcarnitines in Biological Samples
DownloadFall 2012
The field of metabolomics follows the Greek premise where metabolic changes are believed to be indicative of disease. Acylcarnitines, for example, can be dysregulated in the presence of various diseases including genetic metabolic disorders and multiple sclerosis. Liquid chromatography mass...

Fast ignition (FI) decouples the compression and ignition in normal Inertial Confinement Fusion schemes, and can rely on hot electron transport to ignite the compressed core. In order to study electron transport, characteristic K-alpha X-ray emission from copper tracer layers is often employed. A...
