A chamber measuring 14cm diameter, 15cm tall. Temperature: Down to -150°C. Pressure: Down to ~10-5 . Atmospheric Composition: CO2/N2. It provides a facility capable of simulating conditions on icy bodies such as Europa, Ganymede and Enceladus. Illumination is achieved through a dedicated top viewport to irradiate samples using a solar simulator, and there are a variety of viewports (horizontal and angled) to allow observation of the sample and spectral data collection (i.e. spectral reflectance, etc). Using the horizontal viewports for illumination permits low temperature sample transmission measurements to also be performed.
