The MINOS Experiment and NuMI Beamline

NuMI - Neutrinos at the Main Injector

The NuMI Beamline is a facility at Fermilab, near Chicago, which uses protons from the Main Injector accelerator to produce an intense beam of neutrinos which are utilized by the MINOS Experiment; the neutrino beam is directed along a line connecting the two endpoints of the experiment.

MINOS - Main Injector Neutrino Oscillation Search

The MINOS Experiment is a long-baseline neutrino experiment designed to observe the phenomena of neutrino oscillations, an effect which is related to neutrino mass. MINOS uses two detectors, one located at Fermilab, at the source of the neutrinos, and the other located 450 miles away, in northern Minnesota, at the Soudan Underground Mine State Park in Tower-Soudan.

News and Updates

Since MINOS announced results from it's first year of running in March 2006, there have been many talks given at various conferences and seminars. The MINOS for Scientists page, link at left, collects results, presentation slides, and other public information from the MINOS experiment.

A thumbnail summary of results from MINOS compared to other neutrino experiments is given here, expressed as a contour plot in the measured neutrino parameters of Δm² versus sin²2θ
