 Here at Aarhus University we have a very particular research infrastructure, which is called Astrid II, and what it is, it's a synchrotron radiation source, so it produces light in a very wide range of wavelengths, spanning all the way from ultraviolet light up to soft X-rays. So basically the principle is that we have a circulating beam of electrons very close to the speed of light. Just to put it into perspective, if you send these electrons from here to the moon, it will reach there a little bit more than the seconds. In this accelerator we don't accelerate the speed of the electrons in any way. What we exploit is that the circulating electrons, they are put in a close to a circular orbit. It's actually a polygon. This is for instance a bending magnet that will introduce an angle. And this is a tube which has been evacuated from the very good magnet in there. The number of air molecules in there is 100,000 billion times less than out here. This kind of synchrotron radiation is used to a wide variety of experiments and research within most of the natural sciences and including health sciences as well. This is a very particular thing about Aarhus University that we have access to such a big and large-scale facility like Astrid 2. And it's something that we readily make available to the students here to do projects.
