X-ray optics and nano imaging research

Senior scientist(s): Ulrich Vogt

X-ray imaging with x-ray nanobeams [1] is one of the most rapidly developing areas at synchrotron radiation and x-ray free-electron laser facilities around the world. Exciting applications of these nanobeams, i.e., x-ray radiation focused to very small spot sizes in the 10 – 100 nm range, can be found in many fields of science. The unique quality of x-ray nanobeam imaging is the opportunity for direct in-situ and in-operandi experiments exploring very challenging physical environments and giving direct correlation between structure and physical properties.

We design and manufacture diffractive zone plate optics (cf. Fig. 1) with diffraction-limited resolution in the 10 – 100 nm range [2, 3] for nanobeam imaging in the soft and hard x-ray range. Together with partners from Lund University we build the NanoMAX beamline and novel x-ray microscopes at the new Swedish synchrotron source MAX IV. The long term goals are x-ray imaging and diffraction experiments on the 10 nm resolution level. In the past, we investigated the applicability of diffractive zone plates at hard x-ray free electron laser sources [4].
