Abstract
Sintillation detectors have been widely for radiation detection. To achieve the high-sensitive, key elements for the scintillation detector performance are the photon production rate of the scintillator, the photon collection efficiency, the photo-electron efficiency and the energy resolution.
To obtain the high-sensitive, a new detector was developed. The detector consists of plastic-scintillator plates(6*6*1cm3*3layer) and a NaI scintillator(6*6*1cm3*1layer).
In this meeting, the performance of the new detector is discussed.
