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 using Rutherford backscattering spectrometry analysis to obtain radial profiles of W deposition. https://www.spidertattooz.com/Powell-Mahoney-Bloody-Mary-Mix-750ml/
