SSRL Beamline 13 Achieves First Light

Light shines into Beamline 13.

by Kelen Tuttle

On February 14, the first light shone into the Stanford Synchrotron Radiation Laboratory's newest beamline. Beamline 13, which has been under construction for the past two years, will allow new types of soft X-ray material science studies at SSRL.

"Beamline 13 is especially exciting because it has an elliptical polarizing undulator," said Beamline Development Engineer Michael Rowen, who has been working on this project for nearly five years. "With this new tool we can learn more about the magnetic properties of materials and the nature and orientation of chemical bonds."

When finished, the Department of Energy-funded beamline will be configured with three experimental stations: Beamline 13-1 for scanning transmission X-ray microscopy, which will allow the study of condensed matter and surface science and magnetism at the nanometer scale; Beamline 13-2 for photoemission and X-ray absorption spectroscopy, which shows the angles and lengths of bonds both inside materials and at their surfaces; and Beamline 13-3 for resonant coherent scattering and diffraction imaging experiments, which can reveal structure at the nanometer scale.

Commissioning experiments on Beamline 13-2 and Beamline 13-3 are expected to begin later this spring, with commissioning on Beamline 13-1 in the fall of 2008. User experiments on these new experimental stations will commence during the 2009 user run.

What You Need to Know About Stroke

by NIH News in Health

Each year in the United States, there are more than 700,000 strokes. Stroke is the third leading cause of death in the country. And stroke causes more serious long-term disabilities than any other disease. Nearly three-quarters of all strokes occur in people over the age of 65 and the risk of having a stroke more than doubles each decade after the age of 55.

For African Americans, stroke is more common and more deadly—even in young and middle-aged adults—than for any ethnic or other racial group in the United States.

Learning about stroke can help you act in time to save a co-worker, friend, or relative. And making changes in your lifestyle can help you prevent stroke.

Why is Stroke an Emergency?
New treatments are available that greatly reduce the damage caused by a stroke. But you need to arrive at the hospital within 60 minutes after symptoms start to prevent disability. Knowing stroke symptoms, calling 911 immediately, and getting to a hospital are critical. What is a stroke?

A stroke is serious—just like a heart attack. A stroke is sometimes called a "brain attack." Most often, stroke occurs when blood flow to the brain stops because it is blocked by a clot. The brain cells in the immediate area begin to die because they stop getting the oxygen and nutrients they need to function.

What causes a stroke?
There are two kinds of stroke. The most common kind of stroke, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind of stroke, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. Read more in NIH News in Health...

A Wearable History: SLAC Race T-Shirts

by Matt Cunningham

Every year, since 1972, memories are made in the SLAC Run and Walk. Now for the first time, every t-shirt designed for the race is available to be viewed and enjoyed in one place.

"The race itself is so transitory," Ruth McDunn, creator of the SLAC Race Web site and race committee member, said. "It happens on that one day, for a half-hour. This compilation makes it a little more tangible."

Memories are likely to come gushing back into consciousness after viewing the zany designs. Over the years many different people have had a hand in the design process.

Many of the early designs were conceived by Bob Gould and include depictions of Gandalf from The Lord of the Rings. In the following years, members of the SLAC community submitted their own designs before InfoMedia Solutions and McDunn took over.

Besides offering a window into past trends in style, some of the t-shirts serve as a timeline. They provide a superficial glimpse into the events of that specific year.

The Linac Coherent Light Source construction graced last year's t-shirt. Other major events immortalized by SLAC Run t-shirts include the discovery of the Z particle and the creation of the Kavli Institute for Particle Astrophysics and Cosmology.

"It's cool to see the entire 26 year collection of SLAC race shirts gathered together in one place," said InfoMedia Solutions' Terry Anderson. "The SLAC race is a unique event and the t-shirts provide a wearable snapshot of the lab's unique history."
