One more first author peer-review publication has been added to my list. This time a Conference Proceeding – International Conference on Electromagnetic Isotope Separators and Related Topics (EMIS) 2015, that I have participated with a poster contribution (see my Publications), is the Grand Rapids, Michigan, US.
The title is Target nanomaterials at CERN-ISOLDE: synthesis and release data and it is published in Nuclear Instruments and Methods in Physics Research B: Beams Interactions with Materials and Atoms. The full publication can be found in http://www.sciencedirect.com/science/article/pii/S0168583X16002093. Check out the abstract:
Five different nanostructured target materials were tested and operated at ISOLDE in the year of 2014, three of them being carbon-based nanocomposites. In most cases such target materials have higher radioisotope intensities than standard targets and with apparently longer release characteristics. Here, an isotope release profile from a standard calcium oxide (CaO) powder target is compared to the nanostructured one. For all target materials, the synthesis is the key process since it determines the material characteristics and maximum operation temperature which, in turn, defines the final isotope yields (especially for exotic isotopes). An unexpected release of Ar isotopes from a nanometric CaO powder target, with its oven set to room temperature is described and a release mechanism is proposed: spallation recoil momentum from the natCa(p,x)35Ar reaction.
