LCLS Users Test X-ray Laser's Effects on Atoms, Molecules Next

It's been a busy few weeks at the Linac Coherent Light Source. The Atomic, Molecular and Optical instrument's second user group, led by The Ohio State University physicist Louis DiMauro, wrapped up a five-day run early Tuesday morning, and the third group is set to start science today.

The first user group has provided the first experimental test of the LCLS beam, and has given researchers fresh insight into how the world's brightest X-ray laser interacts with matter.

"Right now we are very limited in our knowledge about the actual photon beam," DiMauro said. "No one has ever had access to this kind of light before. So, in terms of learning about the LCLS beam, these events could provide much needed diagnostics."  Read more...

Recovery Act Funds from Fermilab Boost SLAC Accelerator Tech Development

This month, SLAC National Accelerator Laboratory will receive a major financial boost to help drive the design and fabrication of components for a prototype next-generation accelerator being built at Fermi National Accelerator Laboratory. Fermilab has apportioned $3 million in funding from the American Reinvestment and Recovery Act toward development and delivery of radio frequency power couplers and power distribution technology by the Linac and Radio Frequency Design Group in SLAC's Accelerator Research Division. The work has applications for proposed future accelerator projects.

Couplers are essential for delivering radio frequency power to superconducting accelerator cavities like the ones that are proposed to be used in next-generation accelerators. With support from Particle Physics and Astrophysics Division engineers and technicians, SLAC's Linac and Radio Frequency Design Group started providing Fermilab with couplers last May. Since then, they have delivered two pairs of the devices for Fermilab's small-scale prototype of a superconducting radio frequency accelerator


Archives Contest Entries Due Next Week

Break out and photograph that favorite or quirky SLAC tool, project memento or other item; next Tuesday is the final day for submissions in the 2009 Archives Month contest! Submissions will be judged by a diverse panel of SLAC staff recruited by the Archives and History Office, and contest results will be announced on Wednesday, October 28 in SLAC Today. Each submitter will be eligible for a participation prize. See the full contest announcement for more details.

SLAC Green Note: New Executive Order Will Further Sustainability Goals for Federal Agencies

On October 5, 2009, President Obama signed Executive Order 13514, Federal Leadership in Environmental, Energy, and Economic Performance. EO 13514 is intended "to establish an integrated strategy towards sustainability in the Federal Government and to make reduction of greenhouse gas emissions a priority for Federal agencies."

The order builds on and extends the sustainability goals of Executive Order 13423, Strengthening Federal Environmental, Energy, and Transportation Management, established in 2007.

Areas of focus of the new order include, but are not limited to, reporting and reduction of greenhouse gases, increasing energy efficiency; water resource conservation; fossil fuel reduction; waste reduction and pollution prevention; reduction of toxics purchased and used; acquisition of environmentally preferable materials, products and services; sustainable building and electronics stewardship.

The Department of Energy and other federal agencies are developing plans and reviewing existing directives that pertain to the Executive Order sustainability goals. For information on how an external requirement is implemented at SLAC, see SLAC Requirements Management.

For additional information on the new Executive Order, see the White House Press Release.
