摘要
2006 年 6 月 15 日，PAMELA 卫星搭载实验从拜科努尔航天发射场发射升空，自 2006 年 7 月起一直在收集数据。该装置包括飞行时间系统、硅微条磁谱仪、硅钨电磁量能器、反符合系统、簇射尾部计数器闪烁体和中子探测器。这些设备的组合使得能够在宽能量范围 (100 MeV - 数百 GeV) 内对带电宇宙辐射进行高统计量的精确研究。主要科学目标是测量反质子和正电子能谱，以寻找奇异源，例如暗物质粒子湮灭。PAMELA 还在寻找原初反原子核（反氦），并通过精确测量反粒子能谱以及对轻核及其同位素的精确研究来检验宇宙射线传播模型。我们回顾了该装置的状态，并介绍了关于反粒子测量和暗物质间接搜寻的初步结果。
