The Physics of Hard Spheres Experiment (PHaSE) ... will be performed in a multi-angle Light Scattering Instrument (LSI). Within the LSI, seven hard-sphere samples of varying concentrations of three components will be housed in individual glass cells mounted onto a precision rotary stage. The exact ratio of the three components is dependent on the specific volume fraction of solids to liquids desired; each sample will have a slightly different ratio. During operation, each of the samples will be rotated into position for light scattering/data collection activities using both static and dynamic laser sources. Data will be collected using both a high-definition CCD [Charged Coupled Device] camera to record images of the cells and photon counters to measure light scattering.
