High time-resolved, 2D imaging of type-I ELMs in DIII-D using a image-intensified CID camera
The evolution of 2D emission profiles of D-alpha and C III during type-I edge localised modes (ELMs) has been investigated in DIII-D using a tangentially viewing gated, intensified charge-injected device (CID) camera. The measured CIII emission profiles indicate transient inner leg attachment with the arrival of the ELM heat pulse. The measured D-alpha emission profiles during an ELM cycle show...
متن کاملDivertor heat loads in RMP ELM controlled H-mode plasmas on DIII-D
In this paper the manipulation of power deposition on divertor targets at DIII-D by application of resonant magnetic perturbations (RMPs) is analysed. It has been found that heat transport shows a different reaction to the applied RMP depending on the plasma pedestal collisionality. At pedestal electron collisionality above 0.5 the heat flux during the ELM suppressed phase is of the same order ...

متن کاملTH/P4-19 RMP Enhanced Transport and Rotation Screening in DIII-D Simulations
The application of resonant magnetic perturbations (RMP) to DIII-D plasmas at low collisionality has achieved ELM suppression, primarily due to a pedestal density reduction. The mechanism of the enhanced particle transport is investigated in 3D MHD simulations with the NIMROD code. The simulations apply realistic vacuum fields from the DIII-D I-coils, C-coils and measure intrinsic error fields ...
متن کاملPlasma Vertical Stabilization in the Presence of Coil Voltage Saturation in the DIII-D Tokamak∗
An anti-windup compensator is implemented for a given nominal plasma vertical controller guaranteeing global vertical stabilization of the plasma in the presence of actuactor saturation for all reference commands. The anti-windup synthesis problem is to find a nonlinear modification of the nominal linear controller that prevents vertical instability and undesirable oscillations but leaves the n...
