| Outline of Final Research Achievements |
In this research, to achieve a new flat-panel type radiation detector, a new radiation imaging detector based on gaseous radiation detector (glass gas electron multiplier, G-GEM) was proposed and demonstrated. To increase the detection efficiency to hard X-rays, the idea of introducing a solid state converter (tungsten mesh type) was proposed. The converter was designed with monte-carlo simulation. The result showed the converter will increase the detection efficiency of detector compared with the detector without converter. The converter was demonstrated by experiment. In this research, a new imaging signal processing and data acquisition system dedicated for G-GEM was also developed. The system was based on a new analog-to-digital conversion technique called dynamic ToT (dToT). In spite of its reduced number of circuit components, the large-area of 10 cm square was successfully imaged with X-ray.
