The compact linear collider
As the Global Design Effort for the proposed International Linear Collider starts to take shape, an international collaboration of scientists simultaneously works on an alternative linear collider technology that pushes physics and engineering to the edge.

Office of Science Director Orbach outlines bright future for SLAC
Raymond Orbach, director of the Office of Science at the Department of Energy, lavished praise on SLAC's past accomplishments and promising future during a special address Thursday on the Lab's Green.

Ultra-fast science succeeds at SLAC
The Sub-Picosecond Pulse Source (SPPS) collaboration has published data from the first experiments ever using a linear accelerator-based femtosecond x-ray source, and has developed an important tool for ultra-fast science. SPPS makes the world's shortest bunches of electrons in the SLAC linear accelerator and turns them into very bright pulses of x-ray light one thousand times shorter than those made in synchrotron rings like SPEAR3.

The 2005 International Linear Collider Workshop kicked off March 18 by announcing the director for the newly formed Global Design Effort (GDE) for the proposed electron-positron collider.

X-ray blaze on an invisible world
The way that a horse trots intrigued Leland Stanford. After a term as California's governor and with a fortune assembled from building the US transcontinental railway, Stanford lived the life of a country gentleman near his Palo Alto Stock Farm.

Science from a hole in the ground
When Alice famously went down the rabbit hole, she ended up in Wonderland. Now, a group of US scientists from fields as diverse as microbiology and particle physics, rock mechanics and molecular evolution are proposing to go down their own version of the rabbit hole into the scientific wonderland of a Deep Underground Science and Engineering Laboratory.

Understanding the mysteries of high-temperature superconductors
High-temperature superconductors (HTSCs) operate in mysterious ways, but scientists are starting to understand their peculiarities by using a state-of-the-art spectroscopy system at SSRL.

SPEAR3 'breathes' in response to temperature changes
As the sun rises each day, warming the grounds and buildings of SLAC, the entire SPEAR3 facility expands in response. The change is minuscule, on the scale of a few microns--far too slight to observe with the naked eye.

Cosmic tune-up: Cosmic rays help prime BABAR systems
Cosmic rays harmlessly stream through everything on Earth--our bodies, the scintillator counters in the Visitor's Center and the BaBar detectors.

NuSTAR satellite approved for further study by NASA
The Nuclear Spectroscopic Telescope Array (NuSTAR) satellite may soon give astrophysicists a new window on the universe. Designed to image high-energy X-ray radiation, it will capture sharp images of black holes, supernovae, and galactic nuclei. And if NASA gives the project final flight approval early next year, it could be in orbit by the end of the decade.

Beyond the standard model
At almost any particle physics conference, meeting, or lunch table, the phrase "physics beyond the Standard Model" is heard over and over again. What's wrong with the Standard Model, anyway? Why are physicists so sure that there is something beyond it? And why do they think they can find it anytime soon?

Let it rain
Toward the end of a ten-year experiment in 1991, postdoc Hungye Dai of the University of Utah was puzzling over some really unusual data. The experiment was Fly's Eye, which pioneered a new method of studying ultra-high-energy cosmic rays by monitoring the faint flashes of ultraviolet light produced in the sky when the particles hit the upper atmosphere.

Sold on cold
One hot day in August, particle physicists turned cold. That's the day the International Technology Recommendation Panel (ITRP) announced the decision to pursue "cold" superconducting technology for what physicists hope will be the world's next big particle accelerator, the International Linear Collider. Going cold, instead of recommending a "warm" option that had also been under development, has far-reaching consequences for laboratories, scientists, industries and governments across the globe. What does "cold" mean, and why did particle physics choose superconducting technology?

Extreme neutrinos
Kurt Woschnagg has been waiting nine days to catch a plane to the South Pole. He flew for 15 hours from San Francisco to New Zealand, waited several days to spend another eight hours in a cargo plane to McMurdo Station in Antarctica, only to wait again for the weather to clear.

The growth of inflation
It was a true Eureka moment if there ever was one. On the night of December 6, 1979, an obscure Stanford Linear Accelerator Center postdoc was up late, sweating over an even more obscure problem about particles called magnetic monopoles. Looking at his calculations the next day, the usually low-key Alan Guth annotated the words "Spectacular Realization" at the top of the page. Guth had discovered cosmic inflation, an idea which some have later called the most important in cosmology since the big bang.

Fastest gun in the West
SLAC partnered with CalTech, Fermilab, CERN and the University of Florida, along with groups from the UK, Brazil and Korea to defend its title as one of the fastest guns in the West--or, more accurately, the largest bandwidth, which is the computing equivalent.

When it comes to accelerators, what is cold?
Superconductivity arises in special materials at super cold temperatures. At these temperatures--a few degrees above absolute zero--the materials' electrical resistance virtually vanishes.

Echoes of the past in silicon chips
Thermal oxide is the real on-off switch for your computer. The nanometers-thick film on the surface of silicon transistors helps turn on and off the flow of electricity through the transistor, providing the 0 and 1 binary signals modern electronics run on. There are several million transistors on each computer chip.

Shedding light on luminosity
What on earth is an inverse femtobarn and what does it have to do with the number of events an accelerator produces?Fittingly, it was in the farmlands of the Midwest that the term 'barn' was first applied to physics. In December 1942, at a dinner on the campus of Purdue University, physicists M. G. Holloway and C. P. Parker were lamenting the lack of a catchy name for discussing the size of an atomic nucleus.

How many Nobel laureates do you know well enough to nickname?
For Mark Allen (EC), a member of the BaBar collaboration and a graduate student of Aaron Roodman (EC), the answer is now 18. Allen was one of 64 young scientists from the U.S. to attend a five-day symposium of Nobel prize winners in the cobblestoned medieval city of Lindau on a tiny island in the south of Germany. Most of the laureates and researchers who attended this year are, like Allen, physicists.

Is dark matter actually black?
Gravity is the glue that holds together huge objects such as planets and galaxies. After looking at scores of galaxies, however, physicists realized something was amiss. On the outskirts of rotating galaxies, for example, stars were moving too fast for the galaxies to hold together by the gravity from the stars alone.
