Focused Ion BeamFocused Ion Beam (FIB) technology has become a crucial tool in microfabrication, microelectronics, and materials science due to its ability to precisely modify materials at the micro and nanoscale. FIB systems may produce sub-micron sized ion beams, such as gallium, using liquid metal ion sources. [...]

The reference AmSel system extracts americium, Am(III), from PUREX raffinate solutions. It is based on the co-extraction of Am(III), Cm(III) and Ln(III) using the TODGA extracting agent, followed by selective extraction of Am(III) using a water-soluble ligand, SO3-Ph-BTBP.In addition to published data, the coordination of Ln(III) with SO3-Ph-BTBP and its protonation was studied in detail using UV-Vis and NMR. [...]

New water-soluble ligands to selectively strip Am(III) from a solvent loaded with Am(III), Cm(III) and Ln(III) were developed and tested. The former reference ligand, SO3-Ph-BTBP, has the drawback of containing sulphur atoms. [...]

A new CHON AmSEL system was developed based on PrOH-BPTD as the americium-selective complexant. Previous investigations (see deliverable D1.1) found it to show sufficient efficiency and selectivity for americium over trivalent lanthanides and curium. [...]

This document provides the results of an experimental demonstration and validation of a spiked AMSEL flowsheet test, which was conducted at FZJ. The AmSEL process uses TODGA as an extractant and SO3-Ph-BTBP as an Am(III) selective complexant. [...]

This document provides the approach adopted to develop a model for the AmSEL process, using TODGA as an extractant and SO3-Ph-BTBP as a complexing reagent. The constant of the model was determined using single-stage centrifugal contactor experiments. [...]

Halfway through the second period of the Programme oriented Funding (PoF-2), the Institutefor Nuclear Physics (IKP) is focusing on tasks along the lines outlined in the correspondingdocuments for the Helmholtz Association (HGF): foremost this comprises thedesign of and preparations for the High Energy Storage Ring (HESR) of FAIR (Facilityfor Antiproton and Ion Research) as well as for the PANDA experiment. It also includeshadron physics experiments at the Cooler Synchrotron COSY, exploiting the internal experimentsANKE, PAX andWASA and TOF with the extracted COSY beam. [...]

The achievements of the Institut für Kernphysik (IKP) in 2016, the second year of the ongoing period of the"Programme oriented Funding" (PoF), have again been remarkable and clearly demonstrated the scientificvirtue of our research. IKP is an indispensable key player in various projects and a reliable partner inscientific collaborations.The EDM project accomplished a number of important steps towards a high precision storage ring basedEDM measurement.
