Gaseous source of super(83m) Kr conversion electrons for the neutrino experiment KATRIN

The metastable super(83m) Kr with short half-life of 1.83 h is intended as a space distributed source of monoenergetic electrons for energy calibration and systematic studies in the Karlsruhe tritium neutrino experiment (KATRIN).

Description
Summary:The metastable super(83m) Kr with short half-life of 1.83 h is intended as a space distributed source of monoenergetic electrons for energy calibration and systematic studies in the Karlsruhe tritium neutrino experiment (KATRIN). The efficient production of the parent radionuclide super(83) Rb at cyclotron U-120M was implemented. The release of the super(83m) Kr from zeolite (molecular sieve), in which the parent radionuclide super(83) Rb (T sub(1/2)= 86.2 d) was trapped, was studied under various conditions using the gamma spectroscopy. Residual gas analysis of ultra high vacuum over the zeolite was performed as well.
