Content

Modern x-ray imaging methods provide us with images of the invisible. They use bright x-rays which are produced by dedicated synchrotrons. Using a wide range of imaging methods chemical composition, molecular orientation, electron density, magnetism and many other properties of almost any material can be visualized. Because the wavelength of x-rays is much shorter than that of visible light, structures as small as 10nm can be visualized. In addition the pulsed nature of the synchrotrons lends itself to time resolved imaging down to the 102 fs scale.
The Swiss Light Source (SLS) at Paul Scherrer Institut is an example of such a facility. Based on work done there, a range of imaging methods will be presented and it will be shown how they can be used for the scientific projects at Empa.
