Development of Surface Eroding Thermocouples in Small Angle Slot Divertor in DIII-D

Journal Article Ren, J. ; Donovan, D. ; Watkins, J. G. ; ... - IEEE Transactions on Plasma Science

The Surface Eroding Thermocouple (SETC) has proved to be a useful fast local temperature and heat flux diagnostic since its application in DIII-D. The SETC system in DIII-D was upgraded and seven new SETCs were installed in the Small Angle Slot (SAS) divertor to create a localized poloidal array to provide heat flux profiles with sub 10ms temporal resolution. In addition, a smaller SETC was developed to increase the spatial resolution and simplify installation in the SAS divertor. Here, the SETC-containing tiles were re-engineered with double-wide format so that the distance between SETCs and the tile edges is extended tomore »« less

Experimental observation of heat flux mitigation during divertor detachment in the DIII-D small angle slot divertor

Journal Article Ren, J. ; Donovan, D. C. ; Watkins, J. G. ; ... - Nuclear Materials and Energy

Employing an array of surface eroding thermocouples (SETCs), the heat flux measured at the outer strike point of the DIII-D Small Angle Slot (SAS) divertor was found to be reduced by ~50% when the plasma reached the detachment regime compared to the attached state. Reduction in heat flux of similar magnitude has been found in both toroidal field directions (obtained by ramping up the plasma density) but with different characteristics: With the ion B × ∇B drift direction toward the SAS divertor, the heat flux measured by the SETCs first increased as plasma density increased, which may due to reductionmore »« less

3D modeling of boron transport in DIII-D L-mode wall conditioning experiments

Journal Article Effenberg, F. ; Bortolon, A. ; Frerichs, H. ; ... - Nuclear Materials and Energy

DIII-D L-mode experiments with local boron powder injection for real-time wall conditioning have been interpreted for the first time with the 3D plasma edge transport Monte Carlo code EMC3-EIRENE. Local B sourcing in plasma scenarios with upstream densities 1.5•10¹⁹ m^–3 and 2.2 MW heating results in a non-axisymmetric B distribution in the scrape-off layer (SOL) and on the divertor. The SOL frictional flows at high plasma density cause a strong inboard drag of injected impurities (≈90%), while lower background plasma densities tend to result in a more uniform distribution. The thermal forces prevent B deposition in the near SOL whilemore »« less

Utilization of outer-midplane collector probes with isotopically enriched tungsten tracer particles for impurity transport studies in the scrape-off layer of DIII-D (invited)

Journal Article Donovan, David C. ; Unterberg, Ezekial A. ; Stangeby, P. C. ; ... - Review of Scientific Instruments

Triplet sets of replaceable graphite rod collector probes (CPs), each with collection surfaces on opposing faces and oriented normal to the magnetic field, were inserted at the outboard mid-plane of DIII-D to study divertor tungsten (W) transport in the Scrape-Off Layer (SOL). Each CP collects particles along field lines with different parallel sampling lengths (determined by the rod diameters and SOL transport) giving radial profiles from the main wall inward to R-R_sep ~ 6 cm. The CPs were deployed in a first-of-a-kind experiment using two toroidal rings of distinguishable isotopically enriched, W-coated divertor tiles installed at 2 poloidal locations inmore »« less

Fast ion transport during applied 3D magnetic perturbations on DIII-D

Journal Article Van Zeeland, Michael A. ; Ferraro, Nathaniel M. ; Grierson, Brian A. ; ... - Nuclear Fusion

Measurements show fast ion losses correlated with applied 3D fields in a variety of plasmas ranging from L-mode to resonant magnetic perturbation (RMP) edge localized mode (ELM) suppressed H-mode discharges. In DIII-D L-mode discharges with a slowly rotating n = 2 magnetic perturbation, scintillator detector loss signals synchronized with the applied fields are observed to decay within one poloidal transit time after beam turn-o indicating they arise predominantly from prompt loss orbits. Full orbit following using M3D-C1 calculations of the perturbed fields and kinetic profiles reproduce many features of the measured losses and points to the importance of the appliedmore »« less
