Labé : Le Centre de Formation de l’Elevage, un centre sous-régional sans personnel

Le Centre de Formation de l’Elevage de Labé communément appelé CFEL, situé au nord de la ville de Labé à quelques 600 mètres de la Nationale 8 Labé – Mali vit une situation difficile depuis plusieurs années, confronté au manque de personnel, le centre a été rénové par la Banque mondiale en 2018 mais la situation de personnel est sans précédent. Opérationnel depuis 1988, le CFEL vit une situation…

Novel Nozzle Saves Crystals

Thanks to an innovative nozzle, scientists can now analyse more types of proteins while using fewer of the hard-to-get protein crystals. The nozzle can reduce protein consumption eightfold in serial X-ray crystallography experiments, as the team of inventors, headed by DESY scientist Saša Bajt from the Center for Free-Electron Laser Science (CFEL), writes in the journal Scientific Reports. The re…

Dynamics of Electron Clouds Unravelled

Atoms consist of a positively charged nucleus surrounded by negatively charged electrons. In the quantum physics view, the electrons form a fuzzy cloud. The physicists sent bright flashes of an infrared laser into a chamber filled with xenon atoms and recorded the reaction of the xenon electrons with an extremely fast UV camera.

“In the light pulse, the electric field oscillates with a period of…

Laser Metronome Achieves Record Synchronization

Scientists at DESY have set up the world’s most precise ‘metronome’ for a kilometre-wide network. The timing system synchronizes a 4.7-kilometer-long laser-microwave network with 950 attoseconds precision. An attosecond is a quintillionth of a second, or a millionth of a millionth of a millionth of a second. Such installations can provide the beat for recording ultrafast X-raysnapshots of dynamic…

Scientists Shrink Electron Gun to Matchbox Size

In a multi-national effort, an interdisciplinary team of researchers from DESY and the Massachusetts Institute of Technology (MIT) has built a new kind of electron gun that is just about the size of a matchbox. Electron guns are used in science to generate high-quality beams of electrons for the investigation of various materials, from biomolecules to superconductors. They are also the electronso…

Light-driven Atomic Rotations Excite Magnetic Waves

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how the ultrafast light-induced modulation of the atomic positions in a material can control its magnetization. An international research team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matterat…
