704. Non-Linear MHD Simulations for ITER & Non-Linear MHD Modelling of Edge Localized Modes and their Interaction with Resonant Magnetic Perturbations in Rotating Plasmas

Mr Guido Huijsmans (ITER Organization)

Oral

A Validation of MHD models and MHD simulations on current experiments is needed to provide a physics basis for the application of these models to ITER. This paper describes the progress made towards validation in the area of the stability of the H-mode edge pedestal and ELM control. ELM control: pellet pacing The injection of pellets is one of the methods foreseen to control ELM energy losses...

44. Simultaneous Measurement of the ELMs at Both High and Low Field Sides and ELM Dynamics in ELM Crash-Free Period in KSTAR

Mr Hyeon Park (Republic of Korea)

Oral

Following successful characterization of the growth, saturation and bursting process of the Edge Localized Mode (ELM) [1] by a 2D/3D Electron Cyclotron Emission Imaging (ECEI) system in KSTAR H-mode plasmas, the observed mode structure is verified via synthetic image reconstruction based on the BOUT++ code. In successive KSTAR campaigns, a wide range of toroidal mode numbers (~4 < n < ~16) of...

51. Three-Dimensional MHD Analysis of Heliotron Plasma with RMP

Mr Katsuji ICHIGUCHI (Japan)

17/10/2014, 11:25

Oral

In the recent study of magnetically confined fusion plasmas, resonant magnetic perturbations (RMPs) are studied from the viewpoint of the magnetohydrodynamics (MHD) stability against pressure driven modes, because RMPs can locally change the pressure gradient. Particularly, in heliotrons, since pressure driven modes are the most dangerous, the change of the pressure gradient can directly...
