Hard X-ray Workshop: Taking the Unprecedented Even Farther

With the launch of the Linac Coherent Light Source just around the corner, scientists are already talking about ways to extend the capabilties of the world's first operating hard X-ray free electron laser, or FEL.

This was the point of focus for researchers attending last week's workshop, Science Drivers for Hard X-Ray Upgrades to LCLS, held July 29 to 31 in the Research Office Building's Redwood Conference Rooms. The workshop, which drew more than 70 participants from around the world, was organized for researchers to begin considering potential LCLS upgrades with a horizon covering the next 10 years.

When the LCLS sees its first scientific user experiments beginning this fall, the X-ray FEL will operate at energies around 800 eV, and will reach energies as high as 8 keV by the end of next year. Scientists at the workshop discussed ways to increase the energy reach by more than a factor of four, focusing on energies up to 30 and perhaps as high as 50 keV. The access to higher energy X-rays would give scientists an even better look at the properties of matter and would drive research in energy science, materials science and biology.

SLAC physicist Aymeric Robert, who was one of the organizers of the event, said that the workshop was a first step in establishing the scientific case for LCLS upgrades.

"The LCLS was the first machine of its kind to be created, but now that it has had such a startling turn-on we are getting more demanding," he said with a grin. "This workshop was really the start for thinking about what to do next."

Third LCLS Call for Proposals

Experiments with soft and hard X-rays at the AMO, SXR and XPP Stations

Closing date: October 1, 2009

SLAC National Accelerator Laboratory has built the world's first hard X-ray free-electron laser, the Linac Coherent Light Source. It is the goal of LCLS to attract a large number of users from diverse fields and to enable a broad set of important experiments that take advantage of the unique capabilities of LCLS.

The LCLS team invites the world's research community to submit scientific proposals for experiments to be carried out during the time period September through December, 2010. During this period, the two soft X-ray (AMO and SXR) and the hard-ray (XPP) experimental stations at LCLS will be operational. For further details, see the full Third LCLS Call for Proposals.

SLAC Cell Phone Survey

SLAC is very interested in improving cell phone coverage at SLAC. To assist in understanding the needs and negotiating with vendors, the SLAC Computing Division has put together a quick online survey of six questions to find out: how many cell phones are in use at SLAC; what service carriers are used; the number of users for each carrier; and the coverage, etc. An all-hands email was sent on the evening of Friday July 31, and by Monday at 9 a.m. there were already more than 600 responses.

If you have not already responded, please take a few minutes of your time to complete the survey. The more complete the answers, the better we will be able to make our case with carriers and improve coverage, so it is in your interests to participate. This survey will run until Friday, August 7. It is available through a SLAC internet link (requires SLAC Windows login credentials) or intranet link (requires a host on the SLAC network; the visitor's subnet does not work).

If you cannot access one of these sites, please contact Les Cottrell.

Thanks for providing your input.

H-P-S-what?

High Performing Sustainable Building Site Assessment Begins Today

Last December, the final Federal Guidance for High Performance Sustainable Building compliance, or HPSB Guidance, was issued. Since that time, SLAC has been working toward developing a plan that meets the goals and intent of the publication. The guidance document reiterates the requirements of Executive Order 13423 - mandating that all federal sites conform to the High Performance Sustainable Building practices for 15 percent of the site's enduring building population. These practices are outlined within the HPSB Memo of Understanding, signed by the Department of Energy and other federal departments, that describes five specific categories of compliance: integrated design, optimized energy performance, water protection and conservation, enhanced indoor environmental quality and reduced environmental impact of materials.

The practices of HPSB have been documented by the Federal Energy Management Program in what they refer to as the HPSB EB Toolkit, published in May of this year. The toolkit, based upon USGBC LEED for Existing Buildings, is being used as a compliance guideline for a site-wide assessment scheduled to be performed at SLAC beginning today and lasting through the end of September. There will be multiple audit teams surveying multiple building systems including; lighting systems, mechanical equipment, day-lighting systems, water fixtures, air-quality systems, materials and other related HPSB indices. Building managers, the Environment, Safety and Health Department and the Facilities Construction Safety group have been informed of the pending survey work.

So, if you see people in your building and they look suspiciously like engineering survey board-and-pencil-types, they probably are. Please assist the survey teams as you are able. If you have any questions or concerns please call the contract site representative Jonathan Kroeker (x3019). You can also contact Facilities Services (x4960) for immediate assistance.
