Raman Microscope
A Raman microscope coupled with a customized design cryostat is installed in the CASICE laboratory. The aim of the set-up is to investigate the diffusion properties in ice mixtures, and between the ice layers and the substrate. Microspectroscopy is the primary technique to analyse spectroscopic properties in 2D and 3D space, enabling the study of composite materials. With this technique is thus possible to examine samples like meteorites and interstellar dust, and to assess the role of different substrates in the interaction with the ice mantles. The designed set-up is configured with a tunable gas inlet capable to deposit spatially resolved ice sample to address their surface diffusion properties.
