"High-precision Penning-trap determination of the electron capture Q-value in 163-Ho for the determination of the electron neutrino mass"^^ . "The ECHo and HOLMES experiments investigate the effective electron neutrino mass following the least model-dependent approach by studying the kinematic of the electron capture in 163-Ho using cryogenic microcalorimeters.\r\nPossible systematic shifts in the calorimetric measurements can originate from the decay of 163-Ho within the solid gold absorber material of the calorimeter.\r\nIn order to assess if such a systematic shift is present on the current sensitivity level of those experiments, the Q-value of this decay from microcalorimetry is compared to an independently measured one.\r\nThis cumulative thesis is based on the experimental developments towards and the independent measurement of the Q-value of 163-Ho electron capture using Penning-trap mass spectrometry.\r\nIn the first part of this thesis, an injection system for an electron beam ion trap capable of operating with rare isotopes, specifically the artificially produced 163-Ho, was developed for the creation of highly charged ions.\r\nFor the Penning-trap measurement, a single highly charged ion in the correct charge state is required and has to be selected from the different charge states produced within in the electron beam ion trap.\r\nA Bradbury-Nielsen gate and a very fast high-voltage push-pull switch based on silicon carbide MOSFETs was developed within this thesis to separate the different charge states according to their time-of-flight in the beamline following the electron beam ion trap.\r\nThese technical developments allowed a measurement of the Q-value of 163-Ho with the Penning-trap mass spectrometer PENTATRAP as the main result of this thesis."^^ .
