Description
The scanning X-ray microscopy beamline P06 is used frequently for microscopic X-ray imaging of the distribution of metals in biological material like cells, cell clusters and tissues. The experiment is optimized for fast mapping of trace elements from phosphorus to uranium by X-ray fluorescence spectrometry with sub-micrometer resolution. Two-dimensional projections, but also X-ray fluorescence tomography is measured within scan ranges from micrometer to millimeter. Cryogenic sample environments are available. X-ray fluorescence can be complemented by speciation analysis (XAS), and - in case of bones - by XRD. A new development for imaging at highest resolution is the addition of scanning coherent diffraction imaging (ptychography) for imaging of the light element matrix which is invisible for XRF at enhanced resolution. The capability of the instrument is illustrated by various user experiments.
