Development of new apertures for coherent X-ray experiments.
When one performs a coherent small-angle X-ray scattering experiment, the incident beam must be spatially filtered by slits on a length scale smaller than the transverse coherence length of the source which is typically around 10 microm. The Fraunhofer diffraction pattern of the slit is one of the important sources of background in these experiments. New slits which minimize this parasitic back...
متن کاملX-ray film of the month.
X-ray examination of the chest revealed a large circumscribed area of absent aeration in the central portion of the left lung which extended from the axillary portion of the chest to the hilum, merging with the mediastinal structures. In the lateral projection, this circumscribed area was superimposed over the heart. An aneurysm could not be excluded; the area of diminished aeration was thought...
متن کاملDevelopment Of A High Brilliance X-ray Source For Advanced Thin Film Characterization
X-ray based metrology techniques have demonstrated their capabilities for the measurement of critical process parameters on complex microelectronic thin film structures such as layer crystallinity or texture analysis (X-ray Diffraction, XRD), multilayer thickness (X-ray Reflectivity, XRR), material composition (X-ray Fluorescence, XRF) [1]. Achieving the X-ray beam spatial resolution and photon...
