Neutrinos account for as much of the mass of the universe as do stars, they play a crucial role in the production of the chemical elements in the explosions of stars, and they may well explain the origin of the neutrons, protons and electrons that are the building blocks of all the atoms in the universe. “Nothing could be further from the truth. "Neutrinos are always referred to as ghostly particles, as if they are of little interest and have to be apologized for,” Turner says. Michael Turner, NSF’s Assistant Director for Mathematics and the Physical Sciences, believes the neutrinos’ infinitesimal mass belies their significant and ubiquitous impact. The Department of Energy provides the major share of funding for NuMI-MINOS project, with additional support coming from the National Science Foundation (NSF) and from the United Kingdom’s Particle Physics and Astronomy Research Council. MINOS scientists will then use the change from one type of neutrino to another as the key to discovering neutrinos’ secrets. Nonetheless, the detector there should be able to tell if some fraction of the neutrinos have changed from one kind to another during the 2.5-millisecond trip. It will be much the same story in Minnesota as in Illinois. The rest will pass right through with no effect. Because neutrinos interact so rarely, trillions of them will pass through the MINOS near detector each year, but only about 1,500 per year will collide with atoms inside the detector and produce a signal. The other, the 6,000-ton MINOS far detector located a half-mile underground in the Soudan iron mine of northeastern Minnesota, will serve as the final target. ![]() ![]() ![]() One, the 1000-ton MINOS near detector at Fermilab, will monitor the neutrino beam as it heads outward. MINOS refers to a pair of huge underground particle detectors that together comprise the Main Injector Neutrino Oscillation Search. NuMI stands for Neutrinos at the Main Injector, the facility that produces the neutrino beam at the Fermi National Accelerator Laboratory in Batavia, Illinois, outside Chicago. Where do neutrinos come from? What are their masses? And how do they change from one kind to another? The researchers will attempt to answer such questions with the newly completed NuMI-MINOS experiment, which will send pulses of neutrinos on a 450-mile path through the Earth.
