RIKEN and JASRI unveil “SACLA”, Japan’s first X-ray Free Electron Laser (XFEL)

12.04.2011
RIKEN and the Japan Synchrotron Radiation Research Institute (JASRI) have cut the ribbon on a new cutting-edge X-ray Free Electron Laser (XFEL) facility in Harima, the first such facility in Japan and only the second in the whole world.

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.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
