14 GHz ECRIS, MIVOC method
Record Fe ion beams, shown in the table, were produced with the JYFL 14 GHz ECRIS using MIVOC method with commercially available natFe(C5H5)2 (Ferrocene). Ion source was optimised for Fe11+. Material Safety Data Sheets for safe use of Ferrocene can be found from here .
Mixing gas: No mixing gas was used in this run. Typically oxygen is used to maximise the intensities and to minimise the carbon contamination.
Microwave power: 350 W
Acceleration voltage: 10 kV (JYFL extraction system)
Material consumption: The material consumption was not measured in this experiment. Couple of months later the consumption rate of 1 mg/h for the enriched 54Fe was measured. In this experiment the intensity of 52 µA (54Fe11+) was extracted from the JYFL 14 GHz ECRIS. The intensity was not maximised. The enriched MIVOC compound (54Fe(C5H5)2) was synthesised at JYFL and used for the experiment.
