GITR simulations of W transport in the SAS-VW, compared with experimental data, provide a validation opportunity for GITR predictions in a tokamak. The gross erosion rate of W at 3 locations along the SAS-VW was experimentally measured using a multi-chordal divertor spectrometer and a filterscope to quantify characteristic W-I photon emission. The S/XB method is used to calculate the experimental gross erosion flux for direct comparison to GITR results.
