Monoenergetic conversion electrons from the Kr-83m isomeric state have been proven to be useful in the calibration of several tritium neutrino mass and dark matter experiments. In this paper the design and characteristics of the gaseous Kr-83m generator, including the Rb-83/Kr-83m source behavior in tritium, for the KATRIN experiment are presented. Using Si(Li) and silicon drift detectors (SDD) detectors, the half-life of the Kr-83m isomeric state was measured to be 1.8620 +/- 0.0019 h.
