SPARC is being designed to operate with a normalized beta of that rises linearly with a
change in the plasma current. Massive material injection is planned to reduce the disruption …

Two-fluid nonlinear MHD simulations using the TM1 code demonstrate that the formation of
magnetic islands at the top and bottom of the H-mode pedestal, together with the strong …

The effects of kinetic whistler wave instabilities on the runaway-electron (RE) avalanche is
investigated. With parameters from experiments at the DIII-D National Fusion Facility, we …

The interaction of externally applied small non-axisymmetric magnetic perturbations (MP)
with tokamak high-confinement mode (H-mode) plasmas is reviewed and illustrated by …

The plasma response from an external n= 2 magnetic perturbation field in ASDEX Upgrade
has been measured using mainly electron cyclotron emission (ECE) diagnostics and a rigid …

ABSTRACT A newly developed plasma response model, combining the nonlinear two-fluid
MHD code TM1 and toroidal MHD code GPEC run in ideal mode, quantitatively predicts the …

Resonant magnetic perturbations (n= 3 RMPs) are used to suppress large amplitude ELMs
and mitigate naturally occurring'grassy'-ELMs in DIII-D plasmas relevant to the ITER steady …

According to a recent paper [Hu et al., Phys. Plasmas 26, 120702 (2019)], mode penetration
at the top of the pedestal is a necessary and sufficient condition for the suppression of edge …

Areas of agreement and disagreement with present-day models of runaway electron (RE)
evolution are revealed by measuring MeV-level bremsstrahlung radiation from runaway …

Field-line localized ballooning modes have been observed at the edge of high confinement
mode plasmas in ASDEX Upgrade with rotating 3D perturbations induced by an externally …
