Nicknamed “SACLA” (SPring-8 Angstrom Compact Free Electron Laser), the new XFEL’s intense beams will open a unique window onto the minuscule structure of molecules and rapid reaction of chemical species.
When researchers study objects on the atomic scale, they are confronted with a fundamental limitation: they cannot “see” anything smaller than the wavelength of light they use. The new XFEL promises to overcome this limitation with light of a wavelength and intensity like none ever produced before, enabling researchers for the first time to directly observe individual atoms and molecules.
To check that the XFEL is functioning properly and indeed producing this “dream beam”, researchers at SACLA conducted a series of tests on various aspects of the new facility. While confirming the beam’s expected intensity, the tests also indicated that the beam’s wavelength, at 0.8Å (angstroms) or one ten-millionth of a millimeter, was right on the mark. Acceleration of the beam successfully reached a full 7.8 GeV, just shy of the target energy of 8 GeV.
The success of these initial tests marks the first step toward realizing the dream of Angstrom-scale measurements of atomic and molecular structure, setting the stage for full-scale experiments using the new XFEL. The success is also a triumph for Japanese craftsmanship, given that many of the components for SACLA were independently designed and built by Japanese manufacturers.
Pronounced “sa-cu-ra” and meaning “cherry blossom” in Japanese, the facility’s name commemorates these Japanese origins, while its logo symbolizes, among other things, the “8” GeV of energy it will generate once operating at full capacity (see Figure 1). With shared use of the new facility scheduled for the end of fiscal 2011, it will not be long before researchers begin using SACLA to push the boundaries of scientific knowledge, heralding a new era of exploration and discovery.

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
