Neutrino FAQs

These neutrino FAQs are still in need of answers. Photos: Reidar Hahn

Dogged Fermilab reporters recently approached scientists during Neutrino Action Week to find out what they most want to understand about the neutrino.

See their responses in the pictures above. These frequently asked questions still don't have answers, but as we continue to study neutrinos from accelerators and the cosmos, we will get closer to grasping the nuances of these renegade particles.

Antimatter will surf on plasma waves in the particle colliders of the future

From Gizmodo, Aug. 30, 2015

The best way to study the subatomic particles that make up the most fundamental building blocks of our universe is, of course, to smash them into each other with as much energy as possible. And now physicists at SLAC National Accelerator Laboratory say they've found a better way to do that.

Researchers at SLAC's Facility for Advanced Accelerator Experimental Tests (FACET) are especially interested in what happens when they crash high-energy beams of electrons into beams of positrons, their antimatter opposites. To answer the next generation of questions about these particles, however, physicists would need particle accelerators six miles long or more, with current accelerator technology.

Why I love neutrinos

It's Neutrino Action Week here at Fermilab. Today we're launching a new series of videos called Why I Love Neutrinos. We've asked neutrino experts to tell us, in 30 seconds or so, why they love those ghostly, mysterious particles. We've posted the first three videos, and more will be added to the Fermilab YouTube channel in the coming weeks. Subscribe to the YouTube channel to be alerted when a new video is posted.

Construction approved for world's most powerful digital camera

The US Department of Energy has approved the start of construction for a 3.2-gigapixel digital camera — the world's largest — at the heart of the Large Synoptic Survey Telescope. Assembled at SLAC National Accelerator Laboratory, the camera will be the eye of LSST, revealing unprecedented details of the universe and helping unravel some of its greatest mysteries.

The construction milestone, known as Critical Decision 3, is the last major approval decision before the acceptance of the finished camera, says LSST Director Steven Kahn: "Now we can go ahead and procure components and start building it."

Starting in 2022, LSST will take digital images of the entire visible southern sky every few nights from atop a mountain called Cerro Pachón in Chile. It will produce a wide, deep and fast survey of the night sky, cataloguing by far the largest number of stars and galaxies ever observed. During a 10-year time frame, LSST will detect tens of billions of objects — the first time a telescope will observe more galaxies than there are people on Earth — and will create movies of the sky with unprecedented detail. Funding for the camera comes from the DOE, while financial support for the telescope and site facilities, the data management system, and the education and public outreach infrastructure of LSST comes primarily from the National Science Foundation.

The telescope's camera — the size of a small car and weighing more than three tons — will capture full-sky images at such high resolution that it would take 1,500 high-definition television screens to display just one of them.

The search for 'dark matter' and 'dark energy' just got interesting

From The Conversation, Aug. 20, 2015

Only about 5 percent of the universe consists of ordinary matter such as protons and electrons, with the rest being filled with mysterious substances known as dark matter and dark energy. So far, scientists have failed to detect these elusive materials, despite spending decades searching for them. But now, two new studies may be able to turn things around as they have narrowed down the search significantly.

Dark matter was first proposed more than 70 years ago to explain why the force of gravity in galaxy clusters is so much stronger than expected. If the clusters contained only the stars and gas we observe, their gravity should be much weaker, leading scientists to assume there is some sort of matter hidden there that we can't see.
