World's first hard X-ray free-electron laser is on course to completion

Argonne reached another milestone in the design and construction of the Linac Coherent Light Source (LCLS) undulator system.

LCLS will be the world's first X-ray free electron laser to produce hard X-rays when it becomes operational at the Stanford Linear Accelerator Center (SLAC) in 2009. It will be the first X-ray laser to combine the brilliance of laser sources with the penetrating power and atomic sensitivity of X-rays. Argonne is a partner laboratory on the project and is responsible for the 130-meter undulator system, including magnets, support structures, beam diagnostics, controls and vacuum systems.

Undulators are the heart of the LCLS free electron laser, providing a precise magnetic field through which an electron beam will travel. The undulators' magnetic fields force the electrons to oscillate back and forth and produce large amounts of X-rays. These X-rays interact back on the electrons and force them to bunch at X-ray wavelengths. When this occurs, the electrons emit their light coherently, causing a large gain in radiation power that raises the X-rays' intensity.

“Argonne was tapped to participate in this project due to the expertise demonstrated with the Advanced Photon Source undulator systems,” said J. Murray Gibson, associate laboratory director of Argonne's Scientific User Facilities. “An X-ray laser such as LCLS will open up new scientific frontiers and represents an immense technical achievement for the United States. We could not have done this without the partnership of national laboratories, universities and industry.”

“The last of the 40 LCLS undulators was assembled and accepted by Argonne late last month, on time and within budget, from Hi-Tech Manufacturing in Illinois and Metalex Manufacturing in Ohio,” said Argonne LCLS Project Director Geoff Pile. “The LCLS project remains on course for completion in March 2009.”

“This is the first time such ultra-precise undulators were mass-produced in America by non-specialized small businesses,” said Emil Trakhtenberg, Argonne senior mechanical engineer at APS.

Each undulator comprises a precision-tuned array of ultra-strong neodymium-iron-boron permanent magnets and vanadium permendur magnetic poles. The magnets and poles are mounted in aluminum structures bolted into a 3.4-meter-long titanium strongback. The strongback secures the magnet and pole assemblies, counteracts the very high magnetic forces between the upper and lower magnetic arrays, and is critical in determining the thermal and mechanical stability of the undulator. Precision and stability requirements for the LCLS devices far exceed those for existing undulators at the Advanced Photon Source and other light-source facilities.

The pulses of X-ray laser light from LCLS, a fourth-generation light-source, will be shorter and a billion times brighter than can be produced by any other X-ray source available now or in the near future.

“These advanced characteristics will aid scientists in discovering and probing new states of matter, understanding and following chemical reactions and biological processes in real time, imaging chemical and structural properties of materials on the nanoscale, and many new and exciting discoveries we cannot even imagine today,” said Marion White, senior physicist at APS. “The LCLS will enable revolutionary new science.”

The LCLS project is funded by the U.S. Department of Energy and is being constructed by a partnership of three national laboratories: SLAC, Argonne and Lawrence Livermore National Laboratory.

With employees from more than 60 nations, Argonne National Laboratory brings the world's brightest scientists and engineers together to find exciting and creative new solutions to pressing national problems in science and technology. The nation's first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America 's scientific leadership and prepare the nation for a better future. Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy's Office of Science.
