Research Abstract

Silica (SiO2) aerogel has been used as a dust collector in this experiment. Impacting or deposited dust particles are trapped in the aerogel where they remain after the vacuum vent. Then, information of dust transport such as the trapping angle and velocity as well as the particle properties such as size, shape and morphology will be evaluated by surface analysis. Since the amount of dust trapped in the aerogel is two times larger than the dust deposited on an Si target, this dust collection method is useful for estimation of the deposition process without the influence of changing pressure from a high vacuum level to atmosphere.
