摘要
掠入射聚焦型X射线脉冲星望远镜是XPNAV-1卫星的主载荷,其首要科学探测任务是以PSR B0531+21脉冲星为观测目标,根据在轨实测数据恢复脉冲轮廓,实现基于掠入射聚焦型X射线脉冲星望远镜"看得见"PSR B0531+21脉冲星的目标。掠入射聚焦型X射线脉冲星望远镜主要由多层嵌套准Wolter-I X射线光学系统、硅漂移探测器、磁偏转器、电子学、高能粒子防护罩、高稳定结构等关键部组件组成。介绍了脉冲星探测需求、有效载荷工作原理与设计原则、探测任务、主要技术指标以及在轨观测主任务期间观测数据的初步分析结果。
The Grazing Incidence Focusing X-Ray Pulsar Telescope（ i FXPT） is the main payload of XPNAV-1 satellite. With PSR B0531 ＋ 21 pulsar as observation target,the pulsar profile was recovered based on the data obtained by the i FXPT,realizing the main objective that ＂observing＂PSR B0531 ＋ 21 with the i FXPT for the first time in China. The i FXPT is composed of Wolter-I X-ray optics,silicon drift detector,magnetic diverter,electronics,high-energy particle shield and high stable structures. The observation requirements, working principle and design rationale of i FXPT, exploration task, main technical indexes,and the preliminary analysis results of in-orbit data were introduced in this paper.
