A toroidally-continuous row of bulk tungsten (W) tiles was installed near the typical location of the outer strike–point in the Alcator C-Mod divertor and was removed for analysis after two campaigns (3151 plasma discharges). External beam (in–air) particle induced X-ray emission (PIXE) analysis has been used to observe campaign–integrated Wmigration patterns in the otherwise Mo divertor using ...

Accuracy of PIXE analyses depends on inner-shell ionization cross sections. These cross sections are often calculated in the ECPSSR theory; results of its variant (that uses DHS wavefunctions) are employed in the GUPIX package. While the ECPSSR theory agrees well with massive compilations of K x-ray production, it deviates systematically from Lsubshell data – in particular, L1 and L2 cross sect...
