The prototype of a novel particle detection system for the international Deep Underground Neutrino Experiment successfully recorded its first accelerator neutrinos.
Waves describe some of the most extraordinary phenomena in the world. Waves can be simple—the sound of a flute playing a sustained, single note—or they can be complicated mixtures—a musical chord, for example, which is a combination of many sound waves.
Speaking experimentally, the past decade has been the "Decade of the Neutrino." It produced neutrino experiments across three continents, going from the lab, to the nuclear reactor, to the atmosphere, to the sun, and back to the nuclear reactor.
Not only are neutrinos hard to catch, but they also change form as they travel through space. New experiments hope to understand their chameleonic nature.
As spring arrived, so did the kids. Their knees wobbly and eyes wide open, they stayed close to their moms. Dad, weighing more than 2500 pounds, made sure that no harm came the babies' way.
Neutrinos are like no other particle in the universe. The more we learn about these "little neutral ones," the less we seem to understand them. Physicists do not even yet know what type of particle the neutrino is.
As the sun rises each day, warming the grounds and buildings of the Stanford Linear Accelerator Center, the entire SPEAR3 synchrotron facility expands in response.
