Outline of Final Research Achievements

In this research the technology of growth, packaging and array of Strontium Iodide scintillator was established, which has good energy resolution, high light yield and low background radiation. A compton camera with the weight of less than 2kg was designed and fabricated as pin-hole Compton hybrid imager for detecting characteristic X-ray and 662 keV gamma-ray from 137Cs source. The crystals were evaluated by coupling with PMT, APD and SiPM. The resolution of 3% @ 662 keV with PMT and APD, 4% @ 662keV with SiPM was measured and achieved. The used Strontium Iodide scintillators were fabricated liquinert Bridgeman method.
