Dynamics in Ices

This project is concerned with the dynamics of laser- or electron-induced reaction on ices under ultra-high vacuum conditions. For irradiation experiments on condensed (adsorbed) water under ambient conditions, see Water Irradiation.

Lab set-up

We have worked on the electron irradiation of ices with mass-spectrometric and laser-spectroscopic detection of the fragments ejected from the ice. We have collaborated with Dr Greg Kimmel at PNNL on electron-induced within ices using RAIRS of CO as a probe molecules, and have modelled electron-induced experiments of layered ices from the group of Prof McCoustra at Heriot-Watt in Edinburgh.

We are currenlty working with the group of Prof Jean-Hugues Fillion at Sorbonne/Paris on adapting our Surface Velocity Map Imaging Spectrometer to study the UV laser-induced dissociation on and desorption from ice surfaces.
