Secondary ion yield and fragmentation of biological molecules by employing [sup](35)Cl primary ions within the MeV energy domain

In the frame of the project we installed a channeltron detection kit, which is detecting the arrivals of each primary ion, and is installed behind the sample. We are able to measure exactly the primary ion flux and normalize the yields of secondary ions per single primary ion. We demonstrated that the fragmentation of organic molecules under the MeV-SIMS conditions is decreasing with rising primary energy. In addition, we determined the efficiency of the micro-channel plate detector for large molecular ions.

Contrasting allocation of magnesium, calcium and manganese in leaves of tea (Camellia sinensis (L.) Kuntze) plants may explain their different extraction efficiency into tea

With elemental mapping at the high energy focused ion beam we demonstrated specifics in the elemental distribution of physiological elements in the leaf tissue of Camelia Sinensis (tea) plant, and implicated the observed distributions for large variations in the extraction efficiency in the tea.

Arabidopsis halleri shows hyperbioindicator behaviour for Pb and leaf Pb accumulation spatially separated from Zn

With elemental mapping at the high energy focused ion beam we demonstrated specifics in the elemental distribution of accumulating Pb and Zn in arabidopsis plant, which is behaving as hiperaccumulator plant for this heavy elements.
