| Outline of Final Research Achievements |
A high resolution X-ray imaging gaseous detector has been successfully developed with Glass GEM. The imaging system consists of a chamber filled with scintillating gas (Ar/CF4, Kr/CF4, Xe/CF4), inside of which Glass GEM (G-GEM) is mounted for high gain gas multiplication. Since the gas gain of the G-GEM is much higher compared to conventional GEMs, ultra high yield scintillation photons are produced during the avalanche process. These photons can be easily detected by a mirror-lens-CCD-camera system and a high resolution X-ray radiograph is formed. We demonstrate X-ray imaging performance of Glass GEM based X-ray imager with 20 - 60 kV X-ray tube, and combination of various gas (Ar/CF4, Kr/CF4, Xe/CF4). High spatial resolution, high speed image forming and 3D CT is also demonstrated.
