摘要：

A commercial CCD video camera has been used as a room temperature X-ray detector to measure microbeam X-ray beam profiles generated by conical glass capillaries from conventional X-ray tubes. Beam profiles were recorded for two capillaries of diameters 168 and 15 mum using a Cr tube operated at 15 kV, 5 mA. A standard framegrabber was used for image digitization and an image processing system was used for image quantification. Spatial distribution as well as angular divergence were determined by measuring the beam profile at various distances from the capillary exit cross section. Beam profiles from misaligned capillaries have been recorded and split event probability, spatial resolution and radiation damage are discussed.
