Direct preemptive stabilization of neoclassical tearing modes by electron cyclotron current drive in the DIII-D low-torque ITER baseline scenario

Nuclear Fusion, 2023
We report the first preemptive direct stabilization of $m,n = 2,1$ neoclassical tearing modes (NTMs) in DIII-D low-torque ITER baseline scenario plasmas by electron cyclotron waves.

The onset distribution of rotating tearing modes and its consequences on the stability of high-confinement-mode plasmas in DIII-D

Nuclear Fusion, 2023
Analysis of a multi-scenario database of over 13 000 DIII-D H-mode discharges shows that the $m,n = 2,1$ magnetic islands are dominantly pressure gradient driven, stochastically triggered non-linear instabilities at all edge safety factor ( $q_\text{95}$

Machine learning control for disruption and tearing mode avoidance

Physics of Plasmas, 2020
Real-time feedback control based on machine learning algorithms (MLA) was successfully developed and tested on DIII-D plasmas to avoid tearing modes and disruptions while maximizing the plasma performance, which is measured by normalized plasma beta. The

A Study on Hot Tearing in Direct Chill Casting of Al-Mn-Mg Alloys Using a Multi-scale Approach [PDF]

, 2021
A multi-scale approach for simulating hot tearing during the DC casting of aluminum alloys is presented. The novelty of this approach lies in the combination of a macro-scale finite element simulation of the DC casting process with direct prediction of

Revealing hot tearing mechanism for an additively manufactured high-entropy alloy via selective laser melting

Scripta Materialia, 2019
Hot tearing mechanisms of a high-entropy alloy CoCrFeNi additively manufactured by selective laser melting have been investigated. Intergranular hot cracks are present regardless of various parameters used, suggesting poor laser-based printability for ...
