Detecting Neutrinos with the NOvA Detector

NOvA neutrino detector.

Why do neutrinos change flavour?

In less than 100 seconds, Kenneth Long describes neutrinos in the context of quantum mechanics, explaining how they can oscillate between varieties.

 

How to Make a Neutrino Beam

Neutrinos are elusive particles that are difficult to study, yet they may help explain some of the biggest mysteries of our universe. Using accelerators to make neutrino beams, scientists are unveiling the neutrinos' secrets.

 

Neutrinos: Nature's Identity Thieves?

The oscillation of neutrinos from one variety to another has long been suspected, but was confirmed only about 15 years ago. In order for these oscillations to occur, neutrinos must have a mass, no matter how slight. Since neutrinos have long been thought to be massless, in a very real way, this phenomena is a clear signal of physics beyond the known. In this video, Fermilab's Dr Don Lincoln explains how we know it occurs and hints at the rich experimental program at several international laboratories designed to understand this complex mystery.

 

Neutrinos: Nature's Ghosts?

Dr. Don Lincoln introduces one of the most fascinating inhabitants of the subatomic realm: the neutrino. Neutrinos are ghosts of the microworld, almost not interacting at all. In this video, he describes some of their properties and how they were discovered. Studies of neutrinos are expected to be performed at many laboratories across the world and to form one of the cornerstones of the Fermilab research program for the next decade or more.

 

The Search for Antimatter

If you don't have any idea what antimatter is, you don't have to feel bad - the brightest minds in the world have only recently begun to understand what it is and how it works. Hank gives us the run down on what we know about antimatter, and what we're still trying to figure out.

NOvA Neutrino Experiment Installs First Detector Block

Time lapse of Fermilab's NOvA neutrino experiment installing the first of 28 detector blocks in Ash River, MN. Each block is 51 x 51 x 7 feet and when installed will weigh 500 metric tons.

 

NOvA: Exploring Neutrino Mysteries

Neutrinos are a mystery to physicists. They exist in three different flavors and mass states and may be able to give hints about the origins of the matter-dominated universe. A new long-baseline experiment led by Fermilab called NOvA may provide some answers.

Science at the Theater: Extreme Science

On Feb. 27, 2012 at the Berkeley Repertory Theatre, four Berkeley Lab scientists presented talks related to extreme science - and what it means to you. Topics include: Neutrino hunting in Antarctica. Learn why Spencer Klein goes to the ends of the Earth to search for these ghostly particles. From Chernobyl to Central Asia, Tamas Torok travels the globe to study microbial diversity in extreme environments. Andrew Minor uses the world's most advanced electron microscopes to explore materials at ultrahigh stresses and in harsh environments. And microbes that talk to computers? Caroline Ajo-Franklin is pioneering cellular-electrical connections that could help transform sunlight into fuel.

 

Spencer Klein: Neutrino Astronomy in Antarctica

Spencer Klein presents a public talk at UC Berkeley on August 21, 2010, as part of the Science@Cal Lecture Series .

For the past 50 years, scientists have been studying cosmic-ray air showers consisting of billions of particles, produced when an ultra-high energy particle strikes the earth.  Despite enormous effort, we still have not found the cosmic accelerators that create these particles.

One way to find these accelerators is to search for the neutrinos that they produce. Neutrinos travel cosmic distances in a straight line, interact weakly, and can reach us even through dust clouds or other obstructions. Because of their weak interactions, huge detectors are required to observe these neutrinos. Antarctic ice is an attractive material, and several neutrino detectors are being built there. The 1-cubic-kilometer IceCube neutrino observatory is already in partial operation at the South Pole. The proposed 100 cubic-kilometer ARIANNA detector will be located on the Ross Ice Shelf, about 20 miles offshore.

Neutrino Faster Than Speed of Light

On Thursday, the world's biggest physics lab unveiled a shocking finding: that one type of subatomic particle was clocked going faster than the speed of light. If true, it could undercut Einstein's theories. (Sept. 23)
