Implementation of the E×B and Grad‐B Drift in the EMC3 Code and Verification Using the Method of Manufactured Solutions

Contributions to Plasma Physics, EarlyView.
ABSTRACT Effective management of particle and power exhaust is essential for fusion reactor operation, requiring accurate 3D modeling of divertor physics. The EMC3 code is a well‐established Monte Carlo tool for plasma transport in stellarator edge regions, but until now lacked E×B$$ E\times B $$ and diamagnetic drifts.

Impact of error fields and error field correction on heat fluxes in SPARC

Nuclear Fusion
Using a single toroidal array of coils to reduce the $m,n = 2,1$ resonant error field (EF) produced by the misalignment of the axisymmetric coils in SPARC can result in the enhancement of the local divertor heat fluxes. Managing high divertor heat fluxes

Effect of Magnetic Islands on Neoclassical Heat Diffusivity in a Global Tokamak Simulation

Contributions to Plasma Physics, EarlyView.
ABSTRACT Resonant magnetic perturbations (RMPs) alter magnetic field topology via island formation and can modify core transport in toroidal fusion devices. Using the global gyrokinetic particle‐in‐cell code XGC‐S, originally developed for stellarator geometries, we quantify how island topology affects neoclassical heat transport in a circular tokamak ...

Towards a Mean‐Field Braginskii Model for Stellarators

Contributions to Plasma Physics, EarlyView.
ABSTRACT Experiments in the stellarator Wendelstein 7‐X indicate that particle drifts have a significant impact on the plasma in the scrape‐off layer. However, drift effects have been absent in the mean‐field transport codes such as EMC3‐Eirene. For this reason, we present the first steps towards a mean‐field model that incorporates drifts. The code is

Global Stochastic Optimization of Stellarator Coil Configurations [PDF]

, 2021
In the construction of a stellarator, the manufacturing and assembling of the coil system is a dominant cost. These coils need to satisfy strict engineering tolerances, and if those are not met the project could be canceled as in the case of the National

Fusion Energy and Tritium Fuel Cycle: Hydrogen Isotope Separation Technologies and Sorbent Materials

Small Methods, Volume 10, Issue 20, 26 October 2026.
This review surveys sorbent‐based materials for hydrogen isotope separation, a key challenge in fusion fuel processing. Different types of adsorbents are compared in terms of selectivity, kinetics, and operational practicality. Limitations of cryogenic operation and tritium compatibility are highlighted, providing guidance toward efficient, low tritium
