A synchrotron light source is a source of electromagnetic radiation produced by a storage ring, for scientific and technical purposes. The major applications of synchrotron light are in condensed matter physics, materials science, biology and medicine. Metrology Light Source(MLS) is a minor light source near BESSY II. It like a small replica of BESSY. Accelerator and us, just like patient and doctors. We need a stethoscope to know the situation of the patient. My work here is to develop a tool to monitor and adjust the chromacity of this storage ring. The chromacity here is not for the synchrotron light, it is a parameter toRead More →

At the end of the 90s, a consortium of several German research institutions proposed a multi-purpose infrared beamline for the new electron storage ring BESSY II under the acronym IRIS (InfraRotInitiative Synchrotronstrahlung). Funded by two proposals to the BMBF the beamline started operating in 2002 as a Cooperative Research Groupe (CRG) beamline and turned into a BESSY-operated beamline in 2004 at the end of the BMBF funding period.Read More →

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 →

Time is an intriguing concept, isn’t it? We could summarize our own existence in terms of seconds, but there is so much more happening in shorter periods of time, and that’s the main objective of my project. We care about “picoseconds”, an incredibly small subdivision of the second. To help putting things into perspective, there are as many picoseconds in a second as seconds are in THIRTY ONE THOUSAND AND SEVEN HUNDRED years. Yeah, that´s right. But what the hell happens during that time? Well, electrons happen. The guys responsible for driving our whole world as we know it today happen to have an incredibly rich andRead More →
