Production of 83Rb for the KATRIN experiment.
For the neutrino mass determination experiment KATRIN, the long-term stability of the spectrometer voltage is of crucial importance. Therefore, it is planned to control the voltage continuously in a smaller spectrometer, which monitors the position of the conversion electron line emitted in the 32 keV transition in the decay of (83m)Kr. Due to the short half-life of (83m)Kr (t(1/2)=1.83h), it has to be supplied by a long-lived (83m)Kr((83)Rb) generator (t(1/2)=86d). Here, a hitherto unexploited method for the efficient production of (83)Rb and its suitability for its application in the KATRIN monitor spectrometer is described.
