LCLS Undulator System Achieves Milestone at Argonne

The LCLS Project's first production undulator magnet arrived at Argonne National Laboratory (ANL) last week.

Undulators are the heart of the LCLS free electron laser (FEL). They are comprised of alternating permanent magnet blocks made of neodymium-iron-boron and vanadium permendur poles. The magnets and poles are mounted in precision aluminum structures and clamped into a massive 3.4-meter-long titanium strongback, a casing that secures the cylinder in the right position and counteracts the very high magnetic forces between the upper and lower magnetic arrays.

"The undulator magnetic fields and the electron beam are what make the free electron laser work," said Stephen Milton, LCLS project director at ANL. "They are the essence of the FEL." Read more...

Be Safe in the Rain

Slips, trips, and falls are some of our top hazards here at SLAC. During our current wet weather, we need to be especially careful.

While walking between buildings or out to your vehicle, be aware of the slip hazards. Uneven ground surfaces exist in abundance on a diverse and aging work site such as SLAC, and the rain makes it that much more hazardous. Also, mud is being tracked from dirt parking areas or paths into work areas, so we should be especially careful when coming in from the outdoors. While we're trying to stay dry, we also need to stay safe.

Be sure and wear shoes with good soles and low heels; even the fashion conscious should keep a pair of functional shoes to quickly change into for errands across site. (It's a good idea to keep them around as well for emergency response—do we really want to walk home after the big earthquake in 3" heels?)

Some safety suggestions to avoid falls are:
•Use designated paths, not shortcuts
•Avoid hazards like slippery grass and embankments
•Use the handrails on stairs—they're there to keep you safe!
•Stay aware of what you are doing; don't think about what you will do
•Dress for the adventure; use proper clothing and personal protective equipment

We're the best people to watch out for our own safety, so let's stay safe in the rain!

New Art Exhibit in the Research Office Building

The photography of SLAC’s John Van Pelt will grace visitors to the Research Office Building (ROB) beginning on Wednesday, March 22.

Van Pelt's photography focuses on flowers and the landscape of Northern California. Several of Van Pelt’s favorite shots (including the image shown above) were taken at SLAC.

Please join us for an opening reception on March 22 at 4:00 p.m. to meet the artist and enjoy his work.

Fred Kavli's Remarks at the Kavli Building Dedication

It is a special pleasure to be here today for the dedication of this beautiful building in the service of science.

First I want to remember and pay tribute to Leland Stanford and his wife, Jane, who laid the physical and spiritual foundation for this great university, and who in their foresight provided the ample land on which this building stands today.

We owe our gratitude to the many people who have been instrumental in making the Kavli Institute for Astrophysics and Cosmology and the building come about, and give special recognition to President Hennessy, Provost Etchemendy, and the Department of Energy, represented by Robin Staffin. We appreciate the capable work of Roger Blandford, Jonathan Dorfan, and Steven Kahn, who are the prime engines in this effort, and we recognize Steven Chu for his contribution in starting the Institute.
