Ices deposited on a series of cold substrates (20-300 K) vertically mounted on a copper holder connected to a closed cycle cryostat, a 360° rotation stage and a z-linear translation stage
The ice composition and the physico-chemical changes induced upon ion irradiation are monitored by infrared spectroscopy in either a transmission or a reflection mode. Temperature programed desorption (TPD) studies can be performed on both non-irradiated and irradiated ices in order to identify molecules desorbing from the ice layer. A quadrupole mass spectrometer is also attached to the chamber for mass analysis of the desorbed products during irradiation or TPD.
