The Accelerator Neutrino Neutron Interaction Experiment at Fermilab, known as ANNIE, has seen its first neutrino events. (Neutrino events are interactions between neutrinos and water in the detector.) This milestone heralds the start of an ambitious program in neutrino physics and detector technology development.
It is also a cause for celebration by the international ANNIE collaboration, composed of groups from Germany, the United Kingdom and the United States, who have been working diligently over the last two years to design and build the experiment, writes Bob Svoboda, professor of physics in the UC Davis College of Letters and Science and a member of the ANNIE collaboration.
This first observation of neutrinos in the ANNIE detector is expected to be followed by several thousands more over the next two years. Results from ANNIE will help physicists understand the role of nuclear effects in neutrino interactions. Read the full story at Fermilab.
