Time resolved collection and characterization of dust particles moving in the TEXTOR scrape-off layer
Source abstract
Abstract
Moving dust has been collected in the SOL of TEXTOR in a time-resolved way with silica aerogel collectors [1], [2], [3] . The collectors were exposed to the toroidal particle flux in NBI heated discharges during the start-up and flat top phase. Intrinsic dust was collected in several discharges. Other discharges were accompanied with injection of known amounts of pre-characterized dust (W, C flakes and C microspheres) from a position toroidally 120° away from the collector. Particle flux, composition and dust size distribution have been determined with SEM and EDX. Calibration allowed particle velocity estimates to be made. Upper limits for the deuterium content of individual dust grains have been determined by NRA.
