Observation of tungsten emission spectra up to W46+ ions in the Large Helical Device and contribution to the study of high-Z impurity transport in fusion plasmas

Nuclear Fusion
Spectroscopic studies of emissions released from tungsten ions combined with a pellet injection technique have been conducted in Large Helical Device for contribution to the tungsten transport study in tungsten divertor fusion devices and for expansion ...

Recent advance progress of HL-3 experiments

Nuclear Fusion
Since the first plasma realized in 2020, a series of key systems on HL-3 (known as HL-2M before) tokamak have been equipped/upgraded, including in-vessel components (the first wall, lower divertor, and toroidal cryogenic/water-cooling/baking/glow ...

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 ...

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.

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.

Zig-zag deformations of toric quiver gauge theories. Part I. Reflexive polytopes

Journal of High Energy Physics
We study one-parameter families of U(1)2 preserving deformations relating pairs of toric quiver gauge theories on D-branes probing local toric (pseudo) del Pezzo surfaces.

The dynamics of three-forms in thick branes

Journal of High Energy Physics
In this work, we investigate thick brane models with a single three-form field. We find novel solutions for thick braneworlds where only three-forms exist and interact gravitationally in the bulk, both with and without matter fields. We use an additional

The ambient space formalism

Journal of High Energy Physics
We present a new formalism to solve the kinematical constraints due to Weyl invariance for CFTs in curved backgrounds and/or non-trivial states, and we apply it to thermal CFTs and to CFTs on squashed spheres.
