DESCRIPTION:Speakers: Susanne Mertens (Max Planck Institute)\n\nThe KArlsr
 uhe TRItium Neutrino experiment (KATRIN) is searching for the minute impri
 nt of the neutrino mass in the endpoint region of the tritium beta-decay s
 pectrum. KATRIN employs a high-intensity gaseous molecular tritium source 
 and a high-resolution electrostatic filter with magnetic adiabatic collima
 tion to target a neutrino-mass sensitivity of 0.2 eV/c2\, thus improving o
 n previous experiments by an order of magnitude\, after five years of data
 -taking.\n\nThis presentation we will focus on the second data taking phas
 e which took place in autumn 2019. In this physics run\, the tritium-activ
 ity-to-background ratio increased by a factor of three with respect to the
  previous campaign and\, for the first time in the history of direct neutr
 ino mass experiment\, a sub-eV sensitivity to the neutrino mass could be a
 chieved. The talk will introduce the measurement principle of KATRIN\, pre
 sent the latest results\, and give a brief outlook to the ongoing and upco
 ming data taking campaigns.\n\nhttps://agenda.infn.it/event/28548/
