AQUILA: A Laboratory Facility for the Irradiation of Astrochemical Ice Analogues by keV Ions
R. Rácz, S. T. S. Kovács, G. Lakatos +11
The detection of various molecular species, including complex organic molecules relevant to biochemical and geochemical processes, in astronomical settings such as the interstellar…
Sulfur Ion Implantations Into Condensed CO2: Implications for Europa
D. V. Mifsud, Z. Kaňuchová, P. Herczku +12
The ubiquity of sulfur ions within the Jovian magnetosphere has led to suggestions that the implantation of these ions into the surface of Europa may lead to the formation of SO2.…
Energetic Electron Irradiations of Amorphous and Crystalline Sulphur-Bearing Astrochemical Ices
Duncan V. Mifsud, Péter Herczku, Richárd Rácz +10
Laboratory experiments have confirmed that the radiolytic decay rate of astrochemical ice analogues is dependent upon the solid phase of the target ice, with some crystalline molec…
Ozone Production in Electron Irradiated CO2:O2 Ices
Duncan V. Mifsud, Zuzana Kaňuchová, Sergio Ioppolo +9
The detection of ozone (O3) in the surface ices of Ganymede, Jupiters largest moon, and of the Saturnian moons Rhea and Dione, has motivated several studies on the route of formati…
Laboratory Experiments on the Radiation Astrochemistry of Water Ice Phases
Duncan V. Mifsud, Perry A. Hailey, Péter Herczku +8
Water (H2O) ice is ubiquitous component of the universe, having been detected in a variety of interstellar and Solar System environments where radiation plays an important role in…
Comparative Electron Irradiations of Amorphous and Crystalline Astrophysical Ice Analogues
Duncan V. Mifsud, Perry A. Hailey, Péter Herczku +8
Laboratory studies of the radiation chemistry occurring in astrophysical ices have demonstrated the dependence of this chemistry on a number of experimental parameters. One experim…
Mid-IR and VUV Spectroscopic Characterisation of Thermally Processed and Electron Irradiated CO2 Astrophysical Ice Analogues
DV Mifsud, Z Kaňuchová, S Ioppolo +19
The astrochemistry of CO2 ice analogues has been a topic of intensive investigation due to the prevalence of CO2 throughout the interstellar medium and the Solar System, as well as…
Electron Irradiation and Thermal Chemistry Studies of Interstellar and Planetary Ice Analogues at the ICA Astrochemistry Facility
Duncan V. Mifsud, Zoltán Juhász, Péter Herczku +10
The modelling of molecular excitation and dissociation processes relevant to astrochemistry requires the validation of theories by comparison with data generated from laboratory ex…
The Ice Chamber for Astrophysics-Astrochemistry (ICA): A New Experimental Facility for Ion Impact Studies of Astrophysical Ice Analogues
Péter Herczku, Duncan V. Mifsud, Sergio Ioppolo +11
The Ice Chamber for Astrophysics-Astrochemistry (ICA) is a new laboratory end-station located at the Institute for Nuclear Research (Atomki) in Debrecen, Hungary. The ICA has been…
Sulfur Ice Astrochemistry: A Review of Laboratory Studies
Duncan V. Mifsud, Zuzana Kanuchova, Peter Herczku +6
Sulfur is the tenth most abundant element in the universe and is known to play a significant role in biological systems. Accordingly, in recent years there has been increased inter…
Anion and cation emission from water molecules after collisions with 6.6-keV O ions
Zoltán Juhász, Béla Sulik, Elie Lattouf +9
Anion and cation emission following water dissociation was studied for 6.6-keV O + HO collisions. Absolute cross sections for the emission of all positively and…
Ionization of small molecules induced by H, He and N projectiles: comparison of experiment with quantum and classical calculations
S. T. S. Kovács, P. Herczku, Z. Juhász +3
We report the energy and angular distribution of ejected electrons from CH and HO molecules impacted by 1 MeV H, He and 650 keV N ions. Spectra were measured…
