Fermilab Experiment Shoots the Muon

摘要

Batavia, illinols-nobody along the 700-kilometer beamline will notice the trillions of particles zooming underfoot-but scientists are certainly taking notice. Last week, a new experiment at the Fermi National Accelerator Laboratory (Fermilab) began sending neutrinos from an accelerator here to a detector deep underground in a Minnesota iron mine. Physicists working on the detector, known as NuMI/MINOS, have high hopes that the experiment will soon eclipse a similar one in Japan and put the most stringent limits on several properties of the mysterious neutrino.
