Description

The KArlsruhe TRItium Neutrino (KATRIN) experiment is a large-scale experiment with the objective to determine the effective electron anti-neutrino mass with an unprecedented sensitivity of 0.2 eV/c² at 90% C.L. in a model-independent way. The measurement method is based on precision $\beta$-decay spectroscopy of molecular tritium.

The experimental setup consists of a high luminosity windowless gaseous tritium source, a magnetic electron transport system with differential and cryogenic pumping for tritium retention, and an electro-static spectrometer section for energy analysis, followed by a segmented detector system for counting transmitted $\beta$-electrons. Initial commissioning measurements with tritium were performed in 2018.

This talk will give an overview of the KATRIN experiment and its current status.
