SLAC Today

Filling the MMF

One morning in mid-July, a truck rolled into SLAC with a special first delivery. A forklift eased a crate off the flatbed and delivered it to the Magnetic Measurement Facility (MMF). There, MMF technicians Scott Jansson and Ralph Colon opened the box, and a crane lifted SLAC's first LCLS undulator to its test stand.

"That's one down, and thirty nine to go," said Zack Wolf, an engineering physicist at the MMF.

The undulators are part of the LCLS project. Each has a series of magnets positioned and tuned to send an electron beam into an S-shaped path, causing the electrons to emit photons. Wolf and MMF collaborators are currently in the process of tuning the magnetic strength of each of the undulator's 226 poles—as well as of other magnets placed between them along the beam—so the electron beam always follows a precise path.  Read more...

Turner and LCLS Safety

With start of LCLS construction just a few weeks away, safety is a subject that is weighing heavily on the minds of everyone involved. Turner Construction Company—the primary contractor responsible for construction—is taking steps to guarantee the safety of its workers, SLAC employees, and the subcontractors who will be participating in this enormous and complicated project.

Turner has long been considered by the construction industry as a leader in setting high safety standards. Turner's chief approach to job-site injury prevention is embodied in the Turner Building L.I.F.E. (Living Injury Free Everyday) philosophy. One of the program's major objectives is adherence to 100 percent fall protection. Turner's fall protection program stipulates that any individual working six feet or higher must wear fall protection equipment.  OSHA routinely uses Turner as a model of accident prevention in practice. Several workers owe their lives to this Turner policy. One specific example they use is Turner's experience during the renovation of Lambeau Field in 2001; in which two deaths were prevented thanks to their strict fall protection enforcement.

Turner is striving to continue its long tradition of safety during LCLS construction by working closely with its subcontractors to establish a high standard of expectation for adherence to safety guidelines. By working from the assumption that all injuries are preventable, pre-planning safety into their work and integrating worker feedback into their program, Turner and SLAC fully expect to achieve their "zero injury goal."

SLAC Celebrates
Kids Day Tomorrow

Tomorrow morning, 254 children will descend on SLAC for Kids Day '06.

"That's a record," says event co-organizer Teresa Troxel. "We're bursting apart at the seams!"

Children sponsored by a SLAC employee or user will spend the day at a series of workshops ranging from astrophysics to welding, from cryogenics to mechanics. In one session, students will make a vacuum chamber leak-tight; in another, a flashlight.

For a session on catapults, Carpenter Specialist Michael Hughes has just finished building the last of 80 trebuchets. After a lesson in mechanics, each child will put the finishing touches on a trebuchet, a launching device that uses a counterbalanced arm to fling items of choice.  Then they get to experiment with what they can do. Hughes has been able to launch a ping-pong ball about 15 feet.

"What makes Kids Day at SLAC unique is that it's one-on-one, in the workplace, with the people who do that work in a safe way," says Troxel. "There's nobody cooking this up in a classroom."

Volunteers are still needed for two-hour shifts at 9:30 and 12:30. If interested, please contact Teresa Troxel or Michelle Steger
