The current world leading upper limit on the neutrino mass is provided by the KATRIN Experiment with $m_{\nu_e}<0.45\,$eV/c$^2$. To improve the sensitivity on the neutrino mass by at least one order of magnitude new technologies are necessary. In addition to new detector technologies, transitioning from a molecular tritium source to an atomic tritium source is required. Various commercial devices are available that can dissociate H$_2$ and in principle T$_2$ as well. The Karlsruhe Mainz Atomic Tritium Experiment (KAMATE) collaboration aims to investigate the most suited technology and is therefore comparing two thermal dissociators and a plasma based dissociator. The latter is an inductively coupled plasma (ICP) source.
This work presents the characterization of the ICP source with non-radioactive hydrogen by utilizing Optical Emission Spectroscopy (OES). By comparing OES measurements with theoretical calculations from collisional radiative (CR) models, plasma parameters and eventually the number of atoms can be determined. The source can be operated in an capacitive (E-) mode and an inductive (H-) mode. In this poster, results of OES measurements for both modes in terms of line stability, pressure, electron density and electron temperature are presented.
