Status of the neutrino mass experiment KATRIN — •Florian Fränkle for the KATRIN collaboration — Institute for Nuclear Physics, Karlsruhe Institute of Technology (KIT)
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 200 meV/c2 at 90% CL in a model-independent way. The measurement method is based on precision β-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 β-electrons. First commissioning measurements of the complete beamline were performed in November 2016.
This talk will give an overview of the current status of the KATRIN experiment and will present results from the first beamline commissioning measurements.
