A model is presented that describes the excitation of density perturbations and parallel electric fields by standing shear Alfven waves on dipole fields in Earth's magnetosphere. The model includes the effects of electron inertia and gyro-kinetic dispersion, accounting for field-aligned...
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...
Deformation and evolution of solar wind discontinuities through their interactions with the Earth's bow shockDownload
Kabin, Konstantin, Keika, Kunihiro, Rankin, Robert, Carr, C. M., Carlson, C. W., Glassmeier, Karl-Heinz, Magnes, Werner, Lucek, Elizabeth, McFadden, J. P., Dandouras, Iannis, Auster, H. U., Sibeck, D. G., Fornacon, K.-H., Angelopoulos, Vassilis, Baumjohann, W., Nakamura, Rumi
The present study examines the interaction of solar wind discontinuities with the Earth's bow shock, using multipoint observations in the magnetosheath by Time History of Events and Macroscale Interactions During Substorms (THEMIS), Cluster, and Double Star TC1. We focus on the deformation and...
Development of Liquid Chromatography Mass Spectrometry Methods for the Identification and Quantification of Acylcarnitines in Biological SamplesDownload
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...
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)....
Inverse resonance absorption in an inhomogeneous magnetized plasma
The linear mode conversion of a plasma wave to a light wave in a magnetized plasma has been examined theoretically and by computer simulation. This conversion is the inverse of resonance absorption exhibiting an identical dependence on magnetic field and density scale length with an optimum...
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...
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...
We present theory and numerical simulations of strong nonlinear effects in standing shear Alfven waves (SAWs) in the Earth's magnetosphere, which is modeled as a finite size box with straight magnetic lines and (partially) reflecting boundaries. In a low beta plasma it is shown that the...
