Graphalloy Bearings Focus Mesons at Fermilab
Graphite Metallizing Corp. (USA) said its Graphalloy bearings have been put to use by Fermilab, solving an ongoing problem with the focusing system for subatomic particles.
Fermilab is the U.S. Department of Energy's Fermi National Accelerator Laboratory, near Chicago in Batavia, Illinois. The lab focuses its research efforts on the physics of subatomic particles.
Fermilab's Main Injector Neutrino Oscillation Search (MINOS) project is a, "long baseline neutrino experiment designed to observe the phenomena of neutrino oscillations, an effect which is related to neutrino mass."
MINOS and a number of other neutrino oscillation detection experiments are being done to determine if neutrinos have mass -- and if so, what it is. Currently, physicists believe that detecting neutrino oscillation is a promising way to answer that question beyond calculations suggesting 0-15eV. Physicists and cosmologists also believe that understanding neutrinos is the key to understanding a universe of dark matter, supernovas, and even the sun's mechanisms.
The MINOS project involves generating and detecting neutrinos at Fermilab, while focusing them into a beam. That focused beam of neutrinos is aimed a half-mile down and 450 miles away at detectors in the Soudan Underground Mine State Park in northern Minnesota.
Neutrinos populating the beam are created by the NuMI (Neutrinos at the Main Injector) Beamline facility at Fermilab. NuMI focuses a 120 GeV/c proton beam on a graphite target. The collisions create charged mesons ( pions[
