Description
The KATRIN experiment will perform a measurement of the effective electron antineutrino mass with an unprecedented sensitivity of 0.2 eV/c$^2$ (90 % C.L.). An essential calibration and systematic tool in all tritium $\beta$-decay measurements is the metastable isotope $^{83\mathrm{m}}$Kr. With its unique decay characteristics it provides monoenergetic conversion electrons of suitable energies and line widths. The short half-life of 1.83 h allows to introduce the isotope into the experimental apparatus without the risk of long-term contamination.
In this poster we present the first spectroscopic measurements of gaseous $^{83\mathrm{m}}$Kr electrons performed with the full beamline of KATRIN. The results demonstrate the high-resolution performance of the KATRIN spectrometer and the ability to observe a spatially distributed isotropic source of electrons, both required for the tritium $\beta$-spectrum measurement.
