Iron at JYFL

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.
