Anisotropic regularization for inversion of fast-ion loss detector measurements

Nuclear Fusion
We introduce an anisotropic regularization framework for the reconstruction of distribution functions from measurements, utilizing an approach that applies distinct regularization techniques such as non-negative constrained Tikhonov, total variation, and

MHD flows through ferromagnetic rectangular ducts in liquid metal blankets

Nuclear Fusion
In most designs of liquid metal blankets, the reduced activation ferritic martensitic steel with high relative magnetic permeability is proposed as the structural wall material, which will have an obvious influence on the magnetic field distribution ...

First results of a newly built hard x-ray/soft gamma spectrometer imaging system: on the aspect of plasma disruptions

Nuclear Fusion
A new hard x-r ay and soft gamma-ray spectrometer imaging system (HXS) has been built for two-dimensional measurements of plasma emitted photons in the Experimental Advanced Superconducting Tokamak.

Efficient six-dimensional phase space reconstructions from experimental measurements using generative machine learning

Physical Review Accelerators and Beams
Next-generation accelerator concepts, which hinge on the precise shaping of beam distributions, demand equally precise diagnostic methods capable of reconstructing beam distributions within six-dimensional position-momentum spaces.

Rescattering of stimulated Raman side scattering in nonuniform plasmas

Matter and Radiation at Extremes
Rescattering of stimulated Raman side scattering (SRSS) is observed for the first time via two-dimensional (2D) particle-in-cell (PIC) simulations. We construct a theoretical model for the rescattering process, which can predict the region of occurrence ...

Equation of state for boron nitride along the principal Hugoniot to 16 Mbar

Matter and Radiation at Extremes
The thermodynamic properties of boron nitride under extreme pressures and temperatures are of great interest and importance for materials science and inertial confinement fusion physics, but they are poorly understood owing to the challenges of ...

Reducing the total stimulated brillouin scattering of two-color lasers through two-ion decay

Nuclear Fusion
A mechanism coupling the stimulated Brillouin scattering (SBS) of two-color lasers with wavelengths of 527 and 351 $\mathrm{nm}$ via the two-ion decay instability is proposed.
