| 摘 要： | 本文通过对polar自主定位方法的研究,发展了基于gamma射线源在polar塑料闪烁体能量沉淀分布的定位方法,开展了polar自主定位方法的模拟试验验证,分析了polar自主定位可能的影响因素,提出了polar自主定位对电子学系统的设计要求和建议。该研究课题在没有专门定向仪器的情况下,仅采用polar基于Geant4模拟粗略分辨出gamma射线源从哪一个方向入射,分析其显著性。课题成果将应用于polar偏振探测器对gamma射线源的定位,同时可为评估polar电子学系统提供测试依据。

| Abstract: | This paper studied the POLAR self-location method based on the energy disposition.A simulation experiment of the self-localization method for POLAR was carried out.And an analysis was done to discover factors impacting on the self-localization method.Result showed that the impact of both the gamma ray source polarization and the energy resolution of instruments on the method can be neglected,while other factors such as energy spectrum,crosstalk can＇t be neglected. |
