Initial development of the DIII–D snowflake divertor control

Journal Article Kolemen, Egemen ; Vail, P. J. ; Makowski, M. A. ; ... - Nuclear Fusion

Simultaneous control of two proximate magnetic field nulls in the divertor region is demonstrated on DIII–D to enable plasma operations in an advanced magnetic configuration known as the snowflake divertor (SFD). The SFD is characterized by a second-order poloidal field null, created by merging two first-order nulls of the standard divertor configuration. The snowflake configuration has many magnetic properties, such as high poloidal flux expansion, large plasma-wetted area, and additional strike points, that are advantageous for divertor heat flux management in future fusion reactors. However, the magnetic configuration of the SFD is highly-sensitive to changes in currents within the plasmamore »« less

Time-dependent experimental identification of inter-ELM microtearing modes in the tokamak edge on DIII-D

Journal Article Nelson, Andrew Oakleigh ; Laggner, Florian M. ; Diallo, Ahmed ; ... - Nuclear Fusion

In a series of discharges on the DIII-D tokamak, fast vertical plasma jogs are used to induce current perturbations in the steep gradient region of the H-mode edge. These current perturbations directly influence the edge q profile, decoupling the resonant location and instability drive of pedestal-localized microtearing modes (MTMs.) By exploiting this effect, we develop and apply a new experimental technique to track the dynamical frequency evolution of MTMs in the pedestal region, providing a compelling validation of the MTM model. The frequency of potential MTMs is calculated as the Doppler-shifted electron diamagnetic frequency at rational q=m/n surfaces, showing remarkablemore »« less

Interpretative SOL modeling throughout multiple ELM cycles in DIII-D

Journal Article Nelson, A. O. ; Xing, Z. A. ; Izacard, O. ; ... - Nuclear Materials and Energy

Coupling between the UEDGE (edge fluid model), GINGRED (grid generation) and CAKE (equilibrium reconstruction) codes opens the door for automated interpretative scrape-off-layer (SOL) analysis over entire discharges, providing information that is essential in efforts to couple the SOL to core transport codes. In this work, we utilize new developments in the autoUEDGE code [Izacard, O. et al., 60th Annual Meeting of the APS Division of Plasma Physics 53, 11 (2018)] to investigate the behavior of the DIII-D SOL during the temporal evolution of an edge-localized mode (ELM) cycle. Modeled temperature and density profiles in UEDGE are automatically matched to experimentalmore »« less

Pedestal-to-Wall 3D Fluid Transport Simulations on DIII-D

Journal Article Lore, Jeremy D. ; Wolfmeister, Alexis Briesemeister ; Ferraro, Nathaniel M. ; ... - Nuclear Fusion

The 3D fluid-plasma edge transport code EMC3-EIRENE is used to test several magnetic field models with and without plasma response against DIII-D experimental data for even and odd-parity n=3 magnetic field perturbations. The field models include ideal and extended MHD equilibria, and the vacuum approximation. Plasma response is required to reduce the stochasticity in the pedestal region for even-parity fields, however too much screening suppresses the measured splitting of the downstream Te profile. Odd-parity perturbations result in weak tearing and only small additional peaks in the downstream measurements. In this case plasma response is required to increase the size ofmore »« less

Setting the H-mode pedestal structure: variations of particle source location using gas puff and pellet fueling

Journal Article Nelson, Andrew Oakleigh ; Laggner, Florian M. ; Groebner, Richard J. ; ... - Nuclear Fusion

Experiments in DIII-D show that a particle source location inside the top of the H-mode pedestal (pellets) maintains a higher pedestal pressure than an edge source (gas fueling) through a widening of the electron temperature pedestal with reduction of the temperature gradient. The effect of these two fueling schemes on the H-mode pedestal structure was examined in DIII-D by comparing controlled pellet-fueled and gas-fueled discharges across a fueling scan up to 40 torr 1 s^–1. High resolution electron profiles reveal that gas fueling lowers the pedestal pressure as the density profile shifts radially outwards and the separatrix density increases, whilemore »« less
