DESCRIPTION:Speakers: Christian Weinheimer (Institut für Kernphysik\, Uni
 versity of Münster\, Germany)\nSince the discovery of neutrino oscillatio
 n we know that neutrinos have non-zero masses\, but we still do not know t
 he absolute neutrino mass scale\, which is as important for cosmology as f
 or particle physics. The direct search for a non-zero neutrino mass from e
 ndpoint spectra of weak decays is complementary to the search for neutrino
 less double beta-decay and analyses of cosmological data.\nToday the most 
 stringent direct limits on the neutrino mass originate from investigations
  of the electron energy spectra of tritium beta-decay.\n\nThe next generat
 ion experiment KATRIN\, the Karlsruhe Tritium Neutrino experiment\, is imp
 roving the sensitivity from the tritium beta decay experiments at Mainz an
 d Troitsk of 2 eV by one order of magnitude probing the region relevant fo
 r structure formation in the universe. KATRIN uses a strong windowless gas
 eous molecular tritium source combined with a huge MAC-E-Filter as electro
 n spectrometer. To achieve the sensitivity\, KATRIN has been putting many 
 technologies at their limits. The full 70m long setup has been successfull
 y commissioned. From early 2019 on KATRIN is taking high statistics tritiu
 m data hunting for the neutrino mass.\n\nIn this talk a detailed presentat
 ion of the KATRIN experiment and its results from the first KATRIN science
  run will be given. The new results are already bringing KATRIN into the l
 ead position of the field. In the outlook the perspectives of KATRIN for t
 he coming years and new technologies to potentially improve further the se
 nsitivity on the neutino mass will be presented.\n\nhttps://indico.tlabs.a
