Recovering non-Maxwellian particle velocity distribution functions from collective Thomson-scattered spectra
Bryan C. Foo, Derek B. Schaeffer, Peter V. Heuer
Collective optical Thomson scattering (TS) is a diagnostic commonly used to characterize plasma parameters. These parameters are typically extracted by a fitting algorithm that min…
Two-dimensional Thomson scattering in high-repetition-rate laser-plasma experiments
H. Zhang, J. J. Pilgram, C. G. Constantin +7
We present the first two-dimensional (2D) optical Thomson scattering measurements of electron density and temperature in laser-produced plasmas. The novel instrument directly measu…
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…
Diagnosing Magnetic Fields in Cylindrical Implosions with Oblique Proton Radiography
P. V. Heuer, L. S. Leal, J. R. Davies +8
Two experiments on the OMEGA Laser System used oblique proton radiography to measure magnetic fields in cylindrical implosions with and without an applied axial magnetic field. Alt…
Evaluation of direct inversion of proton radiographs in the context of cylindrical implosions
J. R. Davies, P. V. Heuer
Direct inversion of deflectometry data, such as proton radiographs and shadowgraphs, is a well-posed problem with a unique solution for the transverse deflection of each particle o…
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…
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…
Development Considerations for High-Repetition-Rate HEDP Experiments
Scott Feister, Patrick L. Poole, Peter V. Heuer
This paper discusses experimental techniques and considerations associated with the transition to high repetition-rate experiments in High Energy Density Physics (HEDP). We particu…
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…
