Planar Laser Induced Fluorescence Mapping of a Carbon Laser Produced Plasma
R. S. Dorst, C. G. Constantin, D. B. Schaeffer +2
We present measurements of ion velocity distribution profiles obtained by laser induced fluorescence (LIF) on an explosive laser produced plasma (LPP). The spatio-temporal evolutio…
Laser-Driven, Ion-Scale Magnetospheres in Laboratory Plasmas. I. Experimental Platform and First Results
D. B. Schaeffer, F. D. Cruz, R. S. Dorst +7
Magnetospheres are a ubiquitous feature of magnetized bodies embedded in a plasma flow. While large planetary magnetospheres have been studied for decades by spacecraft, ion-scale…
High Repetition Rate Exploration of the Biermann Battery Effect in Laser Produced Plasmas Over Large Spatial Regions
J. J. Pilgram, M. B. P. Adams, C. G. Constantin +7
In this paper we present a high-repetition-rate experimental platform for examining the spatial structure and evolution of Biermann generated magnetic fields in laser-produced plas…
Silica Raman scattering probe for absolute calibration of Thomson scattering spectrometers
Sofiya Ghazaryan, Marietta Kaloyan, Christoph Niemann
We have developed a solid state probe for an absolute irradiance calibration of the Thomson scattering system on the Large Plasma Device (LAPD), based on Raman scattering off silic…
Raster Thomson scattering in large-scale laser plasmas produced at high repetition rate
M. Kaloyan, S. Ghazaryan, C. G. Constantin +5
We present optical Thomson scattering measurements of electron density and temperature in a large-scale (~2 cm) exploding laser plasma produced by irradiating a solid target with a…
On the background-gyroresonant character of the Bell instability
Martin S. Weidl, Dan Winske, Christoph Niemann
We show that the Bell instability, which is widely considered potentially important for cosmic-ray acceleration, is the low-frequency limit of a gyroresonant interaction between th…
How it cramps the flow: three regimes for the saturation of parallel ion-beam instabilities
Martin S. Weidl, Dan Winske, Christoph Niemann
Motivated by recent advances in laboratory experiments on parallel ion-beam instabilities, we present a theoretical framework for and simulations of their evolution towards shock f…
Observations of a Field-Aligned Ion/Ion-Beam Instability in a Magnetized Laboratory Plasma
P. V. Heuer, M. S. Weidl, R. S. Dorst +8
Collisionless coupling between super Alfvénic ions and an ambient plasma parallel to a background magnetic field is mediated by a set of electromagnetic ion/ion-beam instabilities…
Demonstration of an optical mixing technique to drive Kinetic Electrostatic Electron Nonlinear waves in laser produced plasmas
J. L. Kline, B. Afeyan, W. A. Bertsche +4
A nitrogen gas Raman cell system has been constructed to shift a 70 J 527 nm laser beam to 600 nm with 20 J of energy. The 600 nm probe and a 200J, 527 nm pump beam were optically…
