People: Mark Hogan and the FACET Team Move from Theory to Experiments

Mark Hogan wears a T-shirt and running shorts most days of the week, donning slacks and a tie for appropriate events. But his wardrobe is less a fashion statement than a way of life. Hogan has made it a point to participate in at least one major triathlon every year, making time for smaller races when he's not coaching Little League or getting approvals for a state-of-the-art science experiment.

Hogan is the head of the plasma acceleration group in the Advanced Accelerator Research Department. He is a member of the team building FACET, the Facility for Advanced Accelerator Experimental Tests, which will make use of the first two-thirds of the SLAC linac. FACET's plasma acceleration experiments will accelerate electrons on waves of plasma, an approach that promises to accelerate particles up to 1000 times faster than existing technologies. In July, the project received both its Critical Decision 2 and 3 approvals, which recognized the cost, design and schedule of the experiment and authorized the start of construction, respectively.

"I'm looking forward to being a part of all the science," said Hogan, who arrived at SLAC in 1998 as a postdoc, and has been working with the FACET team specifying experimental requirements for the past several years. In a sense, FACET will continue the work accomplished by the Final Focus Test Beam, which operated for user-proposed experiments at SLAC from 1997 until 2006. Due to the unique capabilities of the SLAC linac, these world-leading experiments quickly advanced the field of plasma wakefield acceleration. The FFTB shut down in spring 2006 to make way for the Linac Coherent Light Source.  Read more...

Seasonal Flu Vaccine Coming in October

The fall equinox and end of summer are coming soon... along with flu season. Free seasonal flu shots will be available to SLAC employees beginning in October. Staff can receive vaccinations at an initial "kick-off" fair at the SLAC medical clinic in Building 41 on Tuesday, October 5 from 1:30 to 3:30 p.m. After that, the SLAC Medical Office will offer the vaccine on a walk-in basis every Thursday from 1:30 to 3:30 p.m. at the SLAC clinic.

For more information about seasonal flu and vaccination, see the Stanford University Flu Information page.

Seen Around SLAC: Fall Clean-up Continues

Early last Tuesday and Wednesday, seven dumpsters containing approximately 5000 concrete blocks—more than 200,000 pounds alltogether—were hauled away from the area known as the "Bone Yard," located on the north side of the Klystron Gallery between Sectors 12 and 14.

The blocks, old shielding that had been cleared for disposal, are only the first items to be removed in a continuing Department of Energy cleanup effort. Nine hundred additional large blocks of concrete and miscellaneous pieces of metal have also been relocated to the former RV storage area between Sectors 7 and 10 and prepared for eventual removal and, ideally, recycling.

"The ultimate goal of all our testing and sampling is to be able to find a way to reuse and recycle this material. That's my hope for the future," said Jo Beth Folger of the Facilities Division, who is managing the relocation effort. She emphasized that, regardless of the ultimate fate of the debris, it has all been tested for radiological and environmental hazards. "We're not sending anything offsite that's radioactive," Folger said.
