High-resolution spectroscopy of gaseous Kr conversion electrons with the KATRIN experiment
K. Altenmüller, M. Arenz, W. -J. Baek +124
In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous Kr with the Karlsruhe Tritium…

Calibration of high voltages at the ppm level by the difference of Kr conversion electron lines at the KATRIN experiment
M. Arenz, W. -J. Baek, M. Beck +124
The neutrino mass experiment KATRIN requires a stability of 3 ppm for the retarding potential at -18.6 kV of the main spectrometer. To monitor the stability, two custom-made ultra-…
