The E872 experiment a.k.a. DONUT (Direct Observation of NU Tau) was a part of the recently concluded Fermilab fixed target run. The tau neutrinos were created by 800-GeV/c Tevatron protons interacting in a beam dump, and neutrino interactions were detected in a nuclear emulsion aided by a downstream
