952. (POS-53) The impact of spatio-temporal laser parameters on betatron x-ray generation from a laser-wakefield accelerator

Laser-wakefield acceleration (LWFA) occurs when an intense laser pulse drives a high-amplitude plasma wave in under dense plasma, trapping and accelerating electron bunches to relativistic energies over millimeter to centimeter scales. During the acceleration process, transverse electron oscillations within the plasma wakefield produce high-brightness, ultrashort "betatron" x-rays. The small...

The fluctuation-induced dynamo electric field has been measured in the core of high-temperature EAST tokamak plasmas using Faraday-effect polarimetry and electron cyclotron emission (ECE). The magnetic amplitude of the kink mode (m/n = 1/1) saturates at 30–50 Gauss inside the q = 1 resonant surface. Electron temperature fluctuations reach up to 10% near the resonant surface, where the gradient...

1025. (POS-55) Multivariate Quantification of Gold Nanoparticles Using Nanoparticle-Enhanced LIB

Poster (Non-Student) / Affiche (Non-étudiant(e))

Accurate quantification of gold nanoparticles (AuNPs) is critical for applications in nanotechnology, biomedicine, and functional materials. In this study, nanoparticle-enhanced laser-induced breakdown spectroscopy (NELIBS) is developed as a quantitative optical sensor for direct determination of AuNP concentration using
multivariate calibration.

NELIBS relies on the deposition of...

1069. (POS-56) Experimental investigation of late-time nonlinear evolution of ion-Weibel filaments

Plasma Physics / Physique des plasmas (DPP)

Poster (Non-Student) / Affiche (Non-étudiant(e))

The Weibel instability is a candidate mechanism for the generation of astrophysical seed fields: PIC simulations suggest that Weibel-generated fields might scale much more favorably for long length scales (B ∝ λ^0) than the Biermann-generated fields (B ∝ λ^-1). This possibility, however, requires a mechanism to explain how Weibel field structures grow to large length scales. Existing theory...
