I work at the EMIL beamline which is a very complex system. It provides light for the EMIL laboratory (Energy Materials In-situ Laboratory Berlin) by combining two undulators: UE48 for the soft X-ray range and cryo-cooled U17 for the hard X-ray range. It delivers an energy range from 80 eV to 10000 eV to five end-stations. It has ten mirror chambers to guide the light and three monochromators to select the required energies, and it has a length of 62 m while only 1 m width.Read More →

by Jonas Böhm The last finishing touches are being made to the cryogenic undulator CPMU-17 before it will be installed in the BESSY II storage ring next week. A good moment to look back. The long way of undulators: 70 years old and still up-to-date Home of the first undulator was Stanford. Its linear accelerator (you can see its tunnel in the image) is claimed to be “the world’s most straight object”. In 1952, the Austrian scientist Hans Motz and his team conducted the first experiment, in which a 100-Mev electron beam from the Stanford linear accelerator passed through the undulator. Light radiated by the beam wasRead More →

by Katharina Kolatzki With the new cryogenic undulator CPMU-17 being installed into the BESSY II storage ring, I thought it a good moment to get everyone who may not be that familiar with this essential part of the synchrotron up to speed. What is an Undulator? By now, you might have noticed that undulators are pretty cool things (even the room temperature devices) that are an essential part of synchrotron sources such as BESSY II. In order to understand a little bit more about them, here is a brief introduction to undulators. Synchrotron sources provide especially brilliant light that can be used to examine aRead More →
