Target Plate Particle and Power Flux During ELM Suppression Experiments on DIII-D

Radial profiles of target plate plasma conditions measured with Langmuir probes during ELM suppression using $n=3$ resonant magnetic perturbations [1] have been compared with IRTV heat flux profiles and ```fast'' thermocouples embedded in the divertor tiles. During ELM suppression, $J_{sat}$ and $T_e$ increase and the $J_{sat}$ profile broadens compared to profiles measured between ELMs. An observed three-peak structure appears during ELM suppression and agrees with the spacing and $q_{95}$ dependence predicted by the TRIP3D code. The heat flux calculated from Langmuir probe data (using sheath factor =10 to agree with IRTV) is observed to increase $>$2$\times$ during ELM suppression compared to between ELMs before the RMP is turned on. Global power and particle accounting as well as sheath power transmission at the target plate will be examined.\par \vskip6pt \noindent [1] T.E.
