Description

In previous experiment, some papers reported that circular truncated shape can make suitable radiation output for radiography in comparison with cylinder target. Therefore, we carried out experiments to confirm the influence of the tip shape of the titanium target in the radiation dose using the x-ray tube, which have used by former experiment. It visualized an x-ray source using the Computed Radiography (CR) system and it measured the spatial distribution of the radiation dose relatively. At the same time, tube voltage and current was measured by high-voltage divider and current transformer, respectively. Prepared target shapes are cylinder and circular truncated cone. As the result, in this experiment, a beam spot was seen only with the tip of the target. Moreover, radiation dosage is influenced in distance between target and graphite cathode, rather than in shape of the target. In present study, we did not clearly recognize improvement of x-ray output dosage by using circular truncated cone target as before.
