Modelling of pedestal transport during ELM suppression by external magnetic field perturbations

Nuclear Fusion, 2008
Particle and energy transport in the edge transport barrier is analysed in the presence of magnetic field perturbations from external resonant coils successfully used recently for the mitigation of type I edge localized modes (ELMs). The modification of transport due to charged particle and heat flows along perturbed field lines in a small region near ...

Lock-out Algorithm of Active-Intervention-Type Arc Suppression Device Based on ELM

2020 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia), 2020
The active-intervention-type arc suppression device can effectively prevent arc re-ignition and arc-overvoltage at the fault point in the distribution network. However, under some unfavorable working conditions, it is difficult for the device to extinguish the arc, so the corresponding equivalent circuit is established to derive the expression of the ...

ELM Suppression and Flow Damping with N=1 RMP Fields in Tokamaks Plasmas [PDF]

, 2021
Controlling large edge localized modes (ELMs) is critical for tokamaks operating in H-mode, due to potentially severe consequences on material damages caused by ELM bursts in future large scale devices such as ITER [1]. Resonant magnetic perturbation (RMP) has been extensively applied to mitigate or suppress ELMs [2].

The role of radial particle pinches in ELM suppression by resonant magnetic perturbations

Nuclear Fusion, 2011
The force balance in the plasma edge in a matched pair of DIII-D (Luxon 2002 Nucl. Fusion 42 6149) tokamak discharges with and without resonant magnetic perturbations (RMPs) is evaluated in order to investigate the effects on particle transport of RMP applied for the purpose of suppressing edge-localized modes (ELMs). Experimental

Demonstration of particle exhaust control during ELM suppression by resonant magnetic perturbations in DIII-D

Nuclear Fusion, 2009
A reduction in plasma electron density (‘pump-out’) during the application of resonant magnetic perturbations (RMPs) on DIII-D precedes the suppression of edge localized modes (ELMs) in discharges with low (⩽0.2) electron pedestal collisionalities.
