Abstract :
For non-destructive inspection of relatively massive objects, hard X-ray or gamma-ray of a few hundred keV can be used so that the ray penetrates the target objects. In this energy region, detection of the ray is difficult compared to the one less than ~100keV. To establish electronic readout of large-area gamma-ray imaging, we have developed a GEM-based imaging sensor. The system overview and results of hard X-ray imaging tests are reported.
