DONUT (Direct observation of the nu tau, E872) was an experiment at Fermilab dedicated to the search for tau neutrino interactions. The detector operated during a few months in the summer of 1997, and successfully detected the tau neutrino.[1] It confirmed the existence of the last lepton predicted by the Standard Model.[2] The data from the experiment was also used to put an upper limit on the tau neutrino magnetic moment[3] and measure its interaction cross section.[4]
