Transport of tungsten to collector probes in DIII-D
Collector probes have long been used to measure impurity fluxes in the scrape off layer (SOL) of tokamaks.In this study, collector probes were inserted in the main SOL of DIII-D during the tungsten Metal Rings Campaign, and the W deposits on the probes were analyzed ex situ 1073spx using Rutherford backscattering spectrometry analysis to obtain rad
