On the release of 83mKr — •Makhsud Rasulbaev1, Reiner Vianden1, Karl Maier1, Henrik Arlinghaus2, Marcus Beck2, Tim Schäfer2, Christian Weinheimer2, and Miroslav Zboril2 — 1HISKP der Universität Bonn, Bonn, Germany — 2Institut für Kernphysik der Universität Münster, Münster, Germany
The mono-energetic electrons with the kinetic energy of 17.8 keV from 83mKr (t1/2=1.83 h), daughter isotope of 83Rb decay, are exploited for the calibration and monitoring of the main spectrometer voltage in the KATRIN experiment, which of utmost importance for the long term stability of the measurements. Until now there were problems with the release of 83mKr out of 83Rb source. It was investigated how heating of the Rb source, following vacuum evacuation of the volume can improve the release of 83mKr.
