Angular dependence measurements of Magnum-PSI plasmas using MAST-U angled-tip Langmuir probes
Measurements made using flush-mounted Langmuir probes in tokamaks are difficult to interpret when operating at grazing angles of magnetic field incidence due to the effects of sheath expansion on the probe collection area.

Inferring the scrape-off layer heat flux width in a divertor with a low degree of axisymmetry
Plasma facing components (PFCs) in the next generation of tokamak devices will operate in challenging environments, with heat loads predicted to exceed 10 MW/m2. The magnitude of these heat loads is set by the width of the channel, the ‘scrape-off layer’

Abstract The nonlinear development of ballooning instability and the subsequently induced plasmoid formation in the near‐Earth magnetotail demonstrated in MHD simulations has been proposed as a potential trigger mechanism for substorm onset over the past decade, and their connections to the in situ satellite and ground all‐sky auroral optical ...

Experimental scaling of compressional Alfvén eigenmode stability
Both co-propagating and counter-propagating compressional Alfvén eigenmodes (CAE) are relatively ubiquitous in NSTX plasmas with toroidal field strengths of ⩽4.65 kG, but are largely absent in the NSTX-U plasmas with toroidal fields of 5.7–5.9 kG.

Abstract This article examines how data readiness for AI principles apply to large scientific datasets used to train foundation models. We analyze archetypal workflows across four representative domains—climate, nuclear fusion, life sciences, and materials—to identify common preprocessing patterns and domain‐specific constraints.

Global gyrokinetic simulations of kinetic ballooning mode in NSTX-U plasmas
Understanding the kinetic ballooning mode (KBM) is crucial for optimizing plasma performance in high- β spherical tokamaks. Global gyrokinetic simulations of KBMs in a projected NSTX-U shot are presented using realistic magnetic geometry and plasma ...

Resistive instabilities in toroidal anisotropic plasmas
Resistive singular layer equations are developed by applying the magnetohydrodynamic (MHD) model to toroidal anisotropic plasmas. This work extends the previous ideal MHD theory [Shi et al. Phys. Plasmas 23, 082121 (2016)] to the resistive case.

Relaxation Phenomena in Spherical Tokamak Plasma [PDF]
Dynamics of a relaxation phenomenon observed in Spherical Tokamak experiments, which is called Internal Reconnection Event (IRE), is studied by magnetohydrodynamic computer simulation. Coupling between the torus magnetic field and the external field induced by nonlinear growth of pressure driven instabilities, and resultant formation of tunnel-like ...
