Abstract:
At the BESSY II electron storage ring running by the Helmholtz-Zentrum Berlin (HZB) a transmission soft X-ray microscope (TXM) is operated very successfully for both tomographic imaging of cells [1,2] and for NEXAFS studies in materials science [3-5]. Here, we present the setup of a newly designed beamline (Fig. 1) that will significantly enhance the performance of the HZB TXM. Faster data acquisition over the whole accessible photon energy range together with a possible extension into the tender X-ray range is given. Furthermore, within the photon energy tuning range, two new important absorption edges, namely sulfur and phosphorus, will become accessible for element-specific 3D imaging, in addition to those already available, e.g. at carbon, calcium, titanium and oxygen. Another advantage of this new beamline is that phase contrast X-ray microscopy for thicker specimens will become possible in the tender X-ray photon energy range.
