Tungsten sputtering rates and density profiles predicted using the edge plasma codes EDGE2D-EIRENE and DIVIMP are found to agree within a factor of 4 with measurements of neutral and singly-ionized W spectral line emission in the JET low-field side (LFS) divertor. and within a factor of 2 with SXR. VUV. and bolometric calculations of the W density in the main plasma. https://www.roneverhart.com/Krave-Glass-Beaker-Orb-FREE-GRINDER/
