SAXS/WAXS System at IISER Mohali

Welcome to SAXS/WAXS System at IISER Mohali. This system will enable frontier research in the area of material science, in particular, in the determination of structural parameters/features of particle systems in terms of averaged particle sizes or shape etc. The facility is located in the ground floor of the informatics center.
