Outline of Final Research Achievements

In order to establish low-dose inspection with X-ray or Gamma-ray, high-efficiency gamma-ray imager was developed. Firstly, photon-electron converter was designed and its prototype was fabricated. As for the readout system, an original ASIC called STRIPIX was used so that S/N ratio would be improved. For system verification, X-ray transmission imaging was performed. In addition, X-ray diffraction on powder crystal sample was demonstrated.
