Research Abstract

We have developed CdTe semiconductor imaging detectors with fine position resolution and high energy resolutions for high sensitive observations of gamma-ray lines in the universe. We have achieved and established the CdTe double-sided strip detector which has a few hundredμm position resolution, 1.2 keV energy resolution, and 3.2cm x 3.2 cm large imaging area. Moreover, we applied the CdTe double-sided strip detectors to the compact coded mask camera and the Si/CdTe semiconductor Compton camera, and evaluated the performance of the gamma-ray imaging.
