All segments of first light-generating system installed in world’s brightest X-ray laser

01.03.2016

In the metropolitan area of Hamburg, the installation of the 35 segments of the first of three X-ray light producing components of the European XFEL has been completed. Set into one of the facility’s tunnels, the segments are the core part of three systems called undulators, which are each up to 210 metres long and will produce X-ray laser light exceeding the intensity of conventional X-ray sources by a billion times. These pulses of X-ray radiation are the basis for new revolutionary experimental techniques that will allow scientists to study the nanocosmos, with applications in many fields including biochemistry, astrophysics, and materials science.

The undulator installation is a major step towards the completion of the European XFEL, a 3.4 km-long X-ray free-electron laser facility that will be the world’s brightest X-ray source when completed. It is also one of Europe’s largest research projects and is due to open to users for research in 2017.

“With the 35 segments of the first undulator beam line in place, we have clearly reached a very important milestone in the construction of our facility”, says European XFEL Managing Director Prof. Massimo Altarelli. “The X-ray flashes produced in these systems are the basis for the future research at the European XFEL. We are looking forward to 2017, when they will be used to investigate the smallest details of the structure and function of matter in the molecular world.”

Each of the 35 segments is 5 m long, weighs 7.5 t, and is composed of two girders facing one another, each holding a line of alternating strong permanent magnets. When accelerated electrons pass through the field of alternating polarity generated by the magnets, ultrashort flashes of X-ray laser light are produced. Components between adjacent segments help ensure a consistent magnetic field between them, and control systems allow mechanical movement of components within the undulator, which allows generation of a large spectrum of photon wavelengths.

Design, development, and prototyping work started approximately eight years ago in a joint collaboration with DESY, European XFEL’s largest shareholder. The same technology is also used in a number of projects at DESY, including the X-ray free-electron laser FLASH and the PETRA III storage ring light source.

The undulator system was built through a multinational collaboration. The challenging production involved DESY and Russian, German, Swiss, Italian, Slovenian, Swedish, and Chinese institutes and companies under the leadership of the undulator group of the European XFEL. This includes a number in-kind contributions such as electromagnets for the electron beamline designed and manufactured at several institutes in Russia and tested in Sweden; temperature monitoring units from the Manne Siegbahn Laboratory in Sweden; and movers, phase shifters, and control systems designed and manufactured by the research centre CIEMAT in Spain.

“This was a true synergetic collaboration”, says Joachim Pflüger, group leader of the European XFEL undulator group. “The resources and experience of DESY were essential for the development of the undulator systems. Now there is a great mutual benefit!”

This first completed undulator will generate short-wavelength “hard” X-rays that will be used for experiments with a focus on structural biology and ultrafast chemistry. All three of the undulators planned for the starting phase of the European XFEL will be operational by the end of 2016.

About European XFEL

The European XFEL, currently under construction in the Hamburg area, will be an international research facility of superlatives: 27 000 X-ray flashes per second and a brilliance that is a billion times higher than that of the best conventional X-ray sources will open up completely new opportunities for science. Research groups from around the world will be able to map the atomic details of viruses, decipher the molecular composition of cells, take three-dimensional “photos” of the nanoworld, “film” chemical reactions, and study processes such as those occurring deep inside planets. The construction and operation of the facility is entrusted to the European XFEL GmbH, a non-profit company that cooperates closely with the research centre DESY and other organizations worldwide. By the time the facility starts user operation in 2017, the company will have a workforce of about 280 employees. With construction and commissioning costs of 1.22 billion euro (at 2005 price levels) and a total length of 3.4 kilometres, the European XFEL is one of the largest and most ambitious European research projects to date. At present, 11 countries have signed the European XFEL convention: Denmark, France, Germany, Hungary, Italy, Poland, Russia, Slovakia, Spain, Sweden, and Switzerland.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
