Strontium at JYFL

JYFL 14 GHz ECRIS

Sr was evaporated by using the JYFL miniature oven at JYFL 14 GHz ECRIS.  SrO powder was mixed with Zr powder and then a pellet is pressed.  The oven was operated around 1000˚C to achieved the beam intensities presented in the table. As a result of heating zirconium reacts with SrO and forms ZrO. As a result, metallic Sr is evaporated into the plasma. 

Mixing gas: Oxygen

Microwave power: 400 W

Acceleration voltage: 10 kV (JYFL extraction system)

Material consumption: N/A

Note: Three short separate tests were performed with Zr. We do not have any information about the long term stability/durability.
