Light scattering for complex fluids research on ISS - Investigator dreams and anticipated hardware development

Physics of colloids in space - Flight hardware operations on ISS

“…Two color cameras (1x and 10x magnification) provide realspace images on macroscopic length scales (to complement the Fourier-space light scattering on microscopic length scales). A detailed description of the PCS hardware has been previously given by Ansari et al, 3 while a detailed description of the PCS experiment objectives has been provided by Doherty et al 4 A detailed description of the hardware operations and command capability is provided by Bowen in the PCS Operations Manual. 5 The experiment focuses on the behavior of three different classes of colloid mixtures of tiny manmade particles of either polymethyl methacrylate (PMMA), silica or polystyrene.…”
