论文摘要
近年来，微孔雪崩光电二极管的进展使它们成为闪烁探测器的传感器的吸引力。闪烁检测器的性能与MAPD的物理特性密切相关。对于妻子的这一点，我们将研究三种类型的MAPD-3NK，MAPD-3NM和MAPD-3NM-II，以便在闪烁检测器中使用。研究的雪崩光电二极管具有以下参数，例如低操作电压（90V $ <$ <$ <$ <$ 50V），高像素密度（4000 Pixel/mm^2），高光检测效率（40％）和高增益（6*10^4）。基于MAPD检查了测试闪烁检测器的伽马射线检测性能，并使用不同的伽马射线检查。获得的结果以确认这种闪烁检测器可以成功用于医学中的下一代宠物摄像机。
Recent years getting progress in the area of micropixel avalanche photodiode makes them attractive as sensors for scintillation detectors. The performance of the scintillation detectors is strongly tied to the physical properties of MAPD. For this point of wives, we will investigate three types MAPD-3NK, MAPD-3NM and MAPD-3NM-II for possible use in a scintillation detector. Investigated avalanche photodiodes have the following parameters e.g low operation voltage (90V$<$U$<$50V), high pixel density (4000 pixel/mm^2), high photodetection efficiency (40%) and high gain (6*10^4). Gamma-ray detection performance of tested scintillation detector based on MAPD was checked with different gamma rays. Obtained results to confirm that this kind of scintillation detectors can be successfully used for the next generation of PET cameras in medicine.
