The focus of the experiment was the assessment of f-element thin films prepared with a novel method. The targets were produced in Mainz and brought to GANIL. Terbium thin films were used as targets because of similar behavior of these lanthanides to americium and curium. The thin films were produced by electrochemical deposition from organic solvents such as DMF, DMA or DMSO and deposited on titanium foil with a thickness of 2.1 µm. The terbium triflate salts were dissolved in these solvents and deposited with a constant current density of 2 mA/cm2. The goal was to produce targets with a layer thickness of 1500 µg/cm2 of terbium. Two targets were made with every solvent. Additionally, two targets were made with the classical molecular plating technique with a layer thickness of 500 µg/cm2 as a comparison. Together with a blank titanium foil as a target and two terbium triflate targets, which were prepared and irradiated in 2023, 11 targets were prepared. The targets were brought to GANIL, mounted on the designed wheel and irradiated with an 40Ar6+ ion beam for several hours. While the irradiation happened, the wheel was rotating to distribute the ion beam equally on all targets. After the first irradiation from 08.07 to 10.07 one target from each method and one targets, which was irradiated 2023 were removed and replaced with targets, which were prepared last year but not irradiated yet. That way we can see changes of the targets between the two irradiation steps.
