Description
The KATRIN (Karlsruhe Tritium Neutrino) experiment aims to measure the mass of the electron anti-neutrino with a sensitivity of 200 meV/$c^2$ by measuring the spectrum of the beta electrons close to the kinematic endpoint region.
For monitoring the isotopic composition in the gaseous tritium source a custom-made Laser-Raman-System (LARA) has been developed at the Tritium Laboratory Karlsruhe.
The two approaches used to calibrate the LARA system for trueness <3 % are: i) theoretical intensities together with a spectral intensity standard and ii) highly accurate gas mixtures.
Latest efforts have improved the in-situ calibration via spectral standard with re-calculated theoretical uncertainties and uncertainty analysis.
Recently, the TRIHYDE experiment has been setup which enables cross-checking of the calibration via gas mixtures of all six hydrogen isotopologues and further studies of systematic effects.
This poster presents the benefits and status of both complementary approaches.
