SLAC Today

Monday - May 22, 2006

LCLS Opens Drive Laser Facility

SLAC celebrated another major LCLS milestone Friday with the commissioning and ribbon-cutting ceremony of the Sector 20 building.

A festive atmosphere of refreshments and balloons prevailed and approximately 30 attendees looked on as Project Manager Robert Law, Conventional Facilities Systems Manager David Saenz, and University Technical Representative Jo Beth Folger presented Director of LCLS Construction John Galayda with a symbolic Very Large Key (VLK) to the building.

Since 1962, the Sector 20 site has consisted of a small alcove positioned about a third of the way down the linac.  Read more...

GLAST: One Step
Closer to Launch

Congratulations to the
Worldwide LAT Team

When a large truck, whose interior is atmospherically controlled, rolled out of the SLAC gates on May 11, it marked an important moment for SLAC and its worldwide collaborators. The truck carried the Large Area Telescope (LAT), an instrument that owes its existence to particle physics detectors and the people who know how to make them. As exemplified by its main detection devices, namely silicon strip charged particle tracking devices and cesium iodide calorimeters, the LAT is BaBar in space. It's been a long road for the SLAC staff and a dedicated group of collaborators from France, Italy, Japan, Sweden and the U.S. who designed, modeled, built, assembled and tested the LAT and its many components. Producing a "space-worthy" instrument, as we have come to fully understand, is an extremely demanding engineering task. The instrument, part of the Gamma-ray Large Area Space Telescope (GLAST) mission, has safely arrived at the Naval Research Laboratory (NRL) in Washington, D.C. for pre-launch testing. Following testing, the LAT will go to the spacecraft vendor and, in the fall of 2007, NASA will boost it into space using a massive Delta II rocket.

I want to congratulate the entire LAT collaboration who has worked long and hard to meet the exacting demands of space instrumentation while maintaining extremely tight cost and schedule challenges. It is most gratifying to know that the LAT performs exceptionally well as has been demonstrated these past few months by detailed tests at SLAC using cosmic rays. The LAT meets its design technical specifications and thus provides a grand window into our universe, illuminating exciting questions such as the nature of dark matter, the evolution of stars, and the accelerating powers of super-massive black holes. We at SLAC are most fortunate to host the Instrument Science Operating Center, thus placing us at the center of this exciting scientific adventure.  Read more...

SLAC Seeks Tour Guides

Tour Coordinator Maura Chatwell is looking to recruit SLAC employees and graduate students to talk the talk and walk the walk.

Each day, at least one busload of science enthusiasts makes its way around the site on a tour. This number increases during the summer months. Each tour needs a tour guide: someone who's enthusiastic about science and doesn't mind taking a few hours each month to share this excitement with others.

"I always like explaining things to the general public," said Adam Cunha, a BaBar collaborator who started giving SLAC tours last year. "I think I'm a teacher at heart."  Read more...

Electrical Safety Tip:
Tampering With Lock and Tag

(Photo - LOTO tag)In 2005, lockout/tagout (LOTO) ranked number five among the list of Top 10 OSHA violations. LOTO was also one of the Top 10 most-cited "willful" violations.

Once a lock has been installed and the danger tag has been attached, no one should tamper with a LOTO isolating device without authorization. Changing the status or position of a locked or tagged device is dangerous because others may already have started work under its protection and could be exposed to a hazard they believed isolated. The time to verify the effectiveness of a locking device is at the initial installation.

LOTO is a critical part of the Integrated Safety and Environmental Management System and it only works as well as those using it!
