Building the LCLS: An Image Gallery

Inside the cavernous Far Experimental Hall.

by Brad Plummer

Construction of the Linac Coherent Lights Source (LCLS) continues at a rapid pace. Since the completion of tunneling earlier this year, crews have finished out the Far Experimental Hall and X-ray Tunnel, installed utility systems in the Central Utilities Plant and throughout the facility, and are approaching completion of the Near Experimental Hall (NEH). Support pedestals are now in place inside the Beam Transport Hall and Undulator Hall, and soon installation of vacuum chambers and beam steering magnets will begin. Next week crews will arrive to pave the parking lot adjacent to the NEH.

Over the next few weeks, the focus of the LCLS project will change from conventional facility construction to hardware installation, as major construction draws toward completion.

"Two years ago, among the Stanford Band and notable dignitaries, LCLS broke ground and started construction for the LCLS Conventional Facilities,"said Jess Albino, associate project director of civil construction for LCLS. "Today, the dedication shown by the LCLS team, especially Conventional Facilities staff and Turner Construction, is apparent as we rapidly approach completion and the handover to the technical installation folks. It’s truly amazing—and at the same time humbling."

Views of the latest progress appear in a new gallery of LCLS facility images.

From the Director: Taking a Break

by Persis Drell

(Photo - Persis Drell) This is the time of year when many people at the lab take vacations with their families, and I am no exception! Today and next Friday, there will not be a "From the Director" column because I will be out of town on holiday. I hope that each of you will be able to enjoy some time with your family and friends this summer as well. This has been a challenging year for all of us and I know that I will benefit from some time to rest and gain perspective on the events of the recent months.

New DOE High Energy Physics Web Site

by Elizabeth Clements, Fermilab Today

The drive to understand the world around us is a basic part of our humanity, says the new P5 report. Research in fundamental science—such as high energy physics (HEP)—provides the ideas and discoveries that form the long-term foundation for science and technology as a whole, which in turn drive the global economy, our very way of life and a newly launched Department of Energy (DOE) Web site.

The new DOE Office of High Energy Physics Web site provides resources describing how particle physics benefits society, as well as in-depth information about the nation’s current program and a vision for future plans.

"Particle physics has a compelling story to tell," said Glen Crawford, director of the Research and Technology Division in the Office of High Energy Physics. "From the congressional staffer learning about particle physics to the budget officer investigating a grant proposal, we hope that the new site will serve as a useful resource and tell the story well."

SLAC Safety Review

In August, the Department of Energy (DOE) will conduct a review of SLAC safety programs. In the past several years, SLAC has adopted a strong, formal approach to creating a safe work environment. This program, known as the Integrated Safety and Environment Management System (ISEMS), was reviewed previously by the DOE to validate its content. From August 4–15, five to seven DOE representatives will return to SLAC for an annual review to assess how well we are implementing the safety (non-environmental) aspects of our ISEMS. SLAC staff can view the plan for this review on SLAC Space.

This review offers an excellent opportunity to remind laboratory staff about ISEMS. As the first in a series of ISEMS refresher articles, this story describes the overall program and its five core functions and seven guiding principles. Daily articles next week will cover each of the five core functions in more detail, one core function each day, with relevant examples to help illustrate each function's intent. Read more...

Word of the Week:
Charge Density Wave

by Brad Plummer

In a normal conductive metal, electrons persist in a "sea" wherein they are evenly distributed and the ions, left behind, form a perfectly periodic lattice. A charge density wave occurs under certain circumstances that cause the electrons and ions to couple together to lower their energy. A change in the ions' positions and "waves" in the electron sea are observed, creating new arrangements that prevent the electrons from conducting. Charge density waves are considered quantum mechanical phenomena akin to superconductivity.
