The neutrino mass determination is of particular interest for particle physics, astrophysics, and cosmology. The next generation of the neutrino mass experiment (KATRIN)aims at a model independent determination of the absolute mass of electron neutrino with an unprecedented sensitivity of 0.2eV/c2(90% Confidence Level), by investigating the electronspectrum of the tritium beta-decay. The large-scale experiment is about 70m long from the source section, through the transport sections and a tandem of spectrometers to the detector section. The experiment is currently under construction at the Karlsruhe Institute of Technology(KIT), Campus-North, Germany. I will introduce you to the overview of the KATRIN experiment with its main design and report on its current status.
