FACET Passes Critical Decision 1 Review

On September 10, the FACET project received approval of Critical Decision 1, CD-1, from the Department of Energy, following a successful review in July. The CD-1 approval will move the project through its initial scope, schedule and budget definition phase, and into development of a detailed engineering design.
FACET will generate extremely intense beams with peak currents of roughly 20 kA and energies in excess of 20 GeV. "These beams will be used to study many aspects of beam physics, plasma physics and materials science, however the primary goal for FACET is to understand plasma acceleration," said Tor Raubenheimer, head of SLAC's Accelerator Research Division. "In plasma acceleration, the electric field in a plasma wave is used to accelerate charged particles, such as electrons and positrons, and accelerating fields can be generated that are more than 1000 times higher than in the SLAC linac."
What Is It and How Do I Protect Myself?
H1N1 influenza virus.
With the beginning of fall and the start of school, it's time to prepare for flu season. This year, the new strain of influenza virus H1N1, formerly called "swine flu," deserves added caution. During the past several months, the experience in the Southern Hemisphere's flu season has indicated that H1N1 cases have a severity comparable to seasonal flu. However, SLAC and Stanford are preparing information and health support resources to help the community have a healthy season and to be prepared in the case of a more serious outbreak of the H1N1 virus.
For full details and information about this strain, symptoms, guidance,
protection and more, the best reference is the U.S. Centers for Disease
Control (CDC) 2009
H1N1 Flu Web site.
According to the CDC, the single best way to protect against the flu is
to get vaccinated each year. Unfortunately the H1N1 strain is not
susceptible to the normal seasonal flu vaccine, so a vaccine is under
development for H1N1. The latest projections are that it will become
generally available for the public late in October. In the meantime, SLAC's
Medical Department will be administering the seasonal flu vaccine, for SLAC
employees only, beginning in early October. An announcement will be made
when the seasonal flu vaccines are available. Please be aware that certain
people should not get a flu vaccine without first consulting a physician;
these people are listed on the CDC Web site.
Stanford Report Launches Daily E-news

Today, the Stanford Report launches daily e-mail distribution of university news, events and more.
After 41 years as a weekly print newspaper, the Report
launched its first Web edition in 1997. Two years later, the online
version went to daily updates, while the print newspaper continued weekly. This summer, the publication
became all-electronic after its final print issue
on June 17. After a "beta" test of six weekly e-mails, Stanford Report
daily e-mail delivery today, with continued availability of Stanford news online.
"We're excited about launching the eNews daily for the entire community," said Elaine Ray, Stanford director of campus communications, who led the team that created the publication. "We hope it serves as a main portal of information for faculty, staff and others."
SLAC and Stanford staff, faculty, postdocs, as well as emeritus faculty and
staff will receive the e-mails automatically. Anyone who is interested can
subscribe, following the links on the Stanford Report eNews Web page.
Community members can also suggest story ideas online.
Colloquium Today: From Ostwald to Tesla—New Insights into the Catalysis of Fuel Cells
Today at 4:15 p.m. in Panofsky Auditorium, University of Houston and Technical University Berlin
researcher Peter Strasser will present, "From Ostwald to Tesla—New Insights into the Catalysis of Fuel Cells."
Following his "energetic imperative," Wilhelm Ostwald called upon the science and
engineering community of his time to develop more efficient electrochemical galvanic cells rather than combustion heat engines for energy conversion and power generation. With this demand, he was about 100 years ahead of his peers.
Since Ostwald's time, both electrochemical battery storage cells and electrochemical fuel cells with their distinct fields of application have seen recurring waves of attention. Materials research on either type of cell has yielded impressive new insights and components over past years. Recent highlights include high-energy Li-ion batteries for use in full-electric vehicles as well as low Pt Polymer Electrolyte Membrane fuel cells,
or PEMFCs, in fuel cell hybrid cars. But both of these still face formidable
technical challenges and hence require attention by fundamental science and
engineering, for example, to develop more active and stable electrocatalysts.
In this presentation, Peter Strasser will briefly review the status of battery and fuel cell research and will then focus on his group's recent progress in the materials science and surface catalysis of fuel cell electrocatalysts, to a large extent obtained by use of synchrotron X-ray analytical techniques for the investigation of novel nanostructured catalyst materials. Strasser's group has been able to clarify the extraordinary catalytic performance characteristics of a new class of nanoparticle catalyst, and recently developed X-ray scattering techniques to monitor and understand complex fuel cell catalyst stability behavior in-situ.
colloquium is free and open to all.
