High Speed X-ray Imaging and Spectroscopy with pnCCDs: XRF, XRD and PIXE measurements (and others)
(2016)
For many years pnCCDs have been well known as X-ray detectors for spectroscopic imaging in
many fields of science: X-Ray Fluorescence analysis (XRF), X-ray Diffraction (XRD) with light
sources in large accelerator facilities as well as with laboratory light sources or with X-rays from
celestial sources in X-ray astronomy. A brief introduction in GEXRF (Grazing Emission XRF)
measurements with a laboratory laser produced plasma source will be given, PIXE (Particle Induced
X-ray Emission) measurements and D2XRF (Double Dispersive X-Ray Fluorescence) and Slicing
experiments with pnCCDs coupled to polycapillary optics performed at the BESSY synchrotron will
be shown. Energy-dispersive Laue diffraction with ultra-hard X-rays for the analysis of defects
in metals will conclude the overview of spectroscopic X-ray imaging measurements in the field of
structure and dynamics of matter.
