At extremely high intensities, X-rays stop behaving like the ones in your doctor’s office and begin interacting with matter in very different ways. This “nonlinear” behavior can only be seen at X-ray free-electron lasers; and recent experiments at SLAC have revealed a new, unexpected twist in that behavior that may be one for the textbooks and could change the way these powerful lasers probe matter.

The DOE 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 (LSST).  Assembled at SLAC, the camera will be the eye of LSST, revealing unprecedented details of the universe and helping unravel some of its greatest mysteries.

In 2019, the Large Synoptic Survey Telescope (LSST) will revolutionize our understanding of supernovae. LSST is designed to collect more light and peer deeper into space than ever before. It will move rapidly across the sky and take more images in larger chunks than previous surveys. This will increase the number of supernovae we see by hundreds of thousands per year. - from Symmetry
Exploding stars have an immense capacity to destroy—and create.

Scientists have revealed never-before-seen details of how our brain sends rapid-fire messages between its cells. They mapped the 3-D atomic structure of a two-part protein complex that controls the release of signaling chemicals, called neurotransmitters, from brain cells. Understanding how cells release those signals in less than one-thousandth of a second could help launch a new wave of research on drugs for treating brain disorders.

It is possible that many of these new objects could be satellite galaxies of these larger satellite galaxies, which would be a discovery by itself. “That result would be fascinating,” said Risa Wechsler of SLAC. “Satellites of satellites are predicted by our models of dark matter. Either we are seeing these types of systems for the first time, or there is something we don’t understand about how these satellite galaxies are distributed in the sky.”
The Dark Energy Survey has now mapped one-eighth of the full sky (red shaded region) using the Dark Energy Camera on the Blanco telescope at the Cerro Tololo Inter-American Observatory in Chile (foreground). This map has led to the discovery of 17 dwarf galaxy candidates in the past six months ...

Researchers from SLAC and Stanford University have developed a manufacturing technique that could double the electricity output of inexpensive solar cells by using a microscopic rake when applying light-harvesting polymers.

A new scientific instrument at SLAC  promises to capture some of nature’s speediest processes. It uses a method known as ultrafast electron diffraction (UED) and can reveal motions of electrons and atomic nuclei within molecules faster than a tenth of a trillionth of a second – information that will benefit groundbreaking research in materials science, chemistry and biology.

A study led by researchers at SLAC and the University of California, Los Angeles has demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons. The method may help boost the energy and shrink the size of future linear particle colliders – powerful accelerators that could be used to unravel the properties of nature’s fundamental building blocks.

Graham George and Ingrid Pickering have worked for decades, much of that time at SSRL,  to understand how contaminants in water and soil are taken up by the body and affect human health. Now they are co-leading a new study in Bangladesh that is testing whether giving people selenium supplements can protect them from arsenic poisoning caused by naturally contaminated drinking water.

In the early 1900s, there was no such concept of the age of the universe, says Stanford University associate professor Chao-Lin Kuo of SLAC National Accelerator Laboratory. “Philosophers and physicists thought the universe had no beginning and no end.” - from Symmetry
How can we figure out when the universe began?

Accelerator technology pioneered at SLAC is on its way to powering X-ray science in South Korea. On August 6, the lab shipped one of its unique radio-frequency amplifiers – an XL4 klystron – to Pohang Accelerator Laboratory, where it will become a key component for the optimal performance of a new X-ray free-electron laser under construction.

Story
Tagline
SLAC researchers and facilities explore the frontier questions of science.
Introduction
SLAC National Accelerator Laboratory is one of the 10 Department of Energy (DOE) Office of Science national laboratories and is operated by Stanford University on behalf of the DOE. Since its opening in 1962, SLAC has been helping create the future. We've built the world’s longest particle accelerator, discovered fundamental building blocks of matter and lead countless experiments to test and explore the physical nature of the universe.
