Tungsten and High-Z Impurity Transport Analysis using X-ray Spectroscopy at Wendelstein 7-X in Turbulence-Reduced Scenarios

W and high-Z impurity transport times have been observed to be an order of magnitude higher in ``turbulence-reduced" scenarios, compared to typical plasmas in the Wendelstein 7-X (W7-X) stellarator where turbulent transport dominates. Comparisons of transport times and inferences of the radial profiles of high-Z impurity diffusion coefficients in both scenarios will be presented. Observations of high-Z impurities during the OP2.2 and OP2.3 experimental campaigns in W7-X plasmas were made using the High-Resolution X-ray Imaging Spectrometer (HR-XIS). The HR-XIS is one of three X-ray Imaging Crystal Spectrometer (XICS) systems installed on W7-X that exploit the Bragg diffraction of crystals and is specifically designed for investigating impurity transport. The HR-XIS can make non-perturbative measurements of a selection of impurities such as Al, Ti, Fe, and W existing in charge states from Z of 12 - 49 between 1 - 7 Å by utilizing 8 separate crystals installed on a 3-axis translation and rotation stage. HR-XIS was recently upgraded with a new InSb crystal to view the very bright W46+ 5.6893 Å line. Impurities were injected into W7-X by the Laser Blow-Off system in typical and so-called ``turbulence-reduced" plasma programs, where neoclassical transport is expected to be more influential, to investigate the characteristics of impurity emission lines. The impurity transport diffusion coefficient profiles are inferred through an optimization loop using experimental data and the 1.5D AURORA transport code.
