Workshop: Neutrons for geoscience
Report
The aim of the workshop was to bring together experienced as well as young researchers using neutron beams for Geoscience. 50 scientists of the leading German institutes for Geoscience discussed the different applications: from basic science in studies of structure of material to the high temperatures and pressure in the inner earth.
Another application is the defining of age in minerals with neutron activation analysis. The geoscience is not limited to the earth. At FRM II meteorites of Mars have already been analyzed. With its high precision instrumentation FRM II offers especially for geoscience an ideal research environment.
Prof. Winfried Petry announced, that the experimental facilities will be expanded. Part of the plans is a facility, where conditions of the earth crust can be simulated: extremely high pressure combined with high temperatures. It could help to understand, how water solves in magma under high pressure and temperature and changes the fluidity.
