Twelve European countries contribute to Hamburg XFEL X-ray laser.

€1.22 billion commissioning for the X-ray laser to European XFEL project. Generated incredibly hot intense beam of light to study the structure of matter begun. The so-called injector produced the first electron bunches and accelerated it to speed of light. This project is a master-peace between Engineering and modern Science.

An important part of the X-ray laser European XFEL started operating: the injector, the 45 m-long front stretch of the superconducting particle accelerator, has accelerated the first electrons. The 45 m covered the elementary particles in 0.15 microseconds. The recording of the injector test mode marked an important milestone on the way to the completion of the plant: scientists will find their unique opportunities to develop new materials and environmental protection to take forward.

This injector, which stands on the site of the German Elektro-Systems (DESY) from Hamburg, will enable the underground route of the accelerator with electrons. The electron bunches in so-called Undulators from its orbit are distracted in two experimental halls at a distance of 2.2 and 3.4 km distance.

In each turn, in which the electrons are forced, they emit a sharp X-ray Flash material researchers from all over the world want to use, to develop better catalysts for Chemistry, environmental protection, and energy conversion. Even the Atomic details of living body cells can explore with the X-ray flashes.

Laser pulse strikes billion electrons from an electrode. Remarkably twelve European countries contribute to Hamburg XFEL X-ray laser project.

The injector has a length of 45 m. It hides an ultraviolet laser, which beats out a few billion electrons from an electrode from photocatode with every pulse. These form a package of high-frequency electromagnetic waves 0.13 seconds millionths of to almost the speed of light is accelerated.

This frenzied packages are formed into fine rays in the linear accelerators of superconducting electromagnets, whose winding on cooled to minus 271 C, and kept up speed. Eventually they come undulations in the underground experimental halls in Osdorfer born in Hamburg area.

“Ambitious discovery engine”

“The first electrons in the injector is a milestone for this ambitious discovery engine”, says Professor Helmut Dosch, the Chairman of the Governing Board of the DESY. XFEL will be the world’s most powerful system for the production of X-rays.

In the “gun”, the electrons are released and accelerates bundled packages.

DESY operates three-ring Accelerator and a small electron Laser in Hamburg. All of these large appliances generate X-rays for research. Initial experiments began in the year 2017. 2016 the linear accelerator was moved to Osdorfer re-born as completed and fully commissioned. The first experiments are planned for 2017. Scientists from around the world making this applications useful in different fields. The X-ray laser costs (esimated in 2005 prices) €1.22 billion. Germany bears the brunt. Contribution was made by twelve European countries, including Russia.
