Název v původním jazyce

Gaseous Kr-83m generator of monoenergetic electrons based on Rb-83 deposited in zeolite

Popis výsledku v původním jazyce

The gaseous Kr-83m electron source is currently used in neutrino mass experiments KATRIN and Project 8, dark matter experiments XENON, LUX and DarkSide, and ALICE (CERN) experiment. The main attractive features of this radioactive noble gas are its monoenergetic conversion electrons with well known energies and a half-life of 1.8 h, which is short enough to avoid any long-lasting contamination of the system. The long half-life of the mother Rb-83 isotope (T-1/2 = 86.2 d) enables more time demanding measurement. Particularly, in the neutrino mass experiments with gaseous tritium in which the Kr-83m is applied in the same manner as the tritium, the K-32 conversion electrons with energy conveniently close to the beta spectrum endpoint represent an important test and calibration tool. Here, the design and characteristics of the gaseous Kr-83m generator, including the Kr-83m source itself, for KATRIN (KArlsruhe TRItium Neutrino) experiment are presented.
