Abstract: The objective of the present work is the measurement of diffraction
patterns of polycrystalline materials in a short time. A method is proposed
which opens possibilities to generate real time diffraction patterns using a
normal x-ray CCD camera without cooling. The key element is an effectively
focusing capillary lens. Using the transmission focusing scheme according to
Guinier diffraction patterns of molybdenum and zirconium polycrystals have been
recorded. A 30 Watt x-ray tube with Mo anode and a capillary lens with a focus
spot of 35 μm diameter were employed for that purpose.
Procedures to further improve the quality of the diffraction pattern are
discussed.
