Popis: First comprehensive analysis with PGAA, Prompt Gamma-ray Activation Imaging (PGAI) and neutron tomography (NT) techniques at the research reactor FRM II was tested on a piece of the Allende meteorite. With the PGAA method the bulk elemental composition of the heterogeneous meteorite was determined. Due to the small dimension of the sample, only the 2D elemental distribution of the object was derived with position sensitive PGAI analysis. As an example 2D maps for Si, Fe and Mg are presented. Neutron tomography of the meteorite was carried out with the same cold neutron beam.
