eXTP——增强型 X 射线时序与偏振测量任务
摘要
eXTP 是一项旨在研究物质在极端密度、重力和磁场条件下状态的科学任务。其主要目标包括孤立和双中子星、强磁场系统（如磁星）以及恒星级和超大质量黑洞。该任务搭载了一套独特且前所未有的最先进科学仪器，首次实现了对 0.5-30 keV（及更高）能量范围内宇宙源的同时光谱-时序-偏振测量研究。有效载荷的关键组件包括：光谱聚焦阵列（SFA）——由 11 个 X 射线光学镜头组成，在 2 keV 和 6 keV 下的总有效面积分别约为 0.9 m^2 和 0.6 m^2，配备提供 <180 eV 光谱分辨率的硅漂移探测器；大面积探测器（LAD）——由 640 个可展开的硅漂移探测器组成，在 6 至 10 keV 之间总有效面积约为 3.4 m^2，光谱分辨率 <250 eV；偏振聚焦阵列（PFA）——由 2 台 X 射线望远镜组成，在 2 keV 下的总有效面积为 250 cm^2，配备成像气体像素光电偏振计；宽视场监视器（WFM）——由 3 个编码掩模宽视场单元组成，配备位置灵敏硅漂移探测器，每个单元覆盖 90 度 x 90 度的视场。eXTP 国际合作组织主要包括中国科学院和中国大学的主要机构，以及几个欧洲国家和美国的主要机构。eXTP 的前身 XTP 任务概念自 2011 年起已被选中并获资为中国科学院空间科学战略性先导科技专项中的所谓背景任务之一。欧洲的强力参与显著增强了 eXTP 的科学能力。该任务的计划发射日期早于 2025 年。
