Primary Effects of Energetic Particles in Liquids under Extreme Thermodynamics Conditions




The generation of radical species triggered by nuclear reactions which produce elevated Linear Energy Transfer (LET) ionizing particles in aqueous media, as well as their reactivity, may be drastically affected by extreme thermodynamic conditions (temperatures higher than 300°C, pressures higher than 100 MPa, acidic or alkaline pH). Such effects are studied by experimental and computational techniques.



A related project under development concerns the use of new energetic particle sources driven by high intensity lasers. These sources deliver femtosecond bunches of MeV-electrons and also high LET protons, carbons which rendering possible the study of their interaction with various molecular systems, probed by optical spectroscopy.
