摘要
高能粒子探测器（HEPD-02）是第二颗中国地震电磁卫星（CSES-02）的有效载荷，由意大利利马杜合作组设计和建造。其目的是探测宇宙射线和辐射带俘获粒子，动能范围对电子为3-100 MeV，对质子为30-200 MeV。HEPD-02是首个使用基于单片有源像素传感器（MAPS）的径迹探测器的空间探测器。MAPS提供了高空间分辨率、低噪声、增强的鲁棒性和低生产成本。由于严格的功耗要求，在空间中运行MAPS面临重大挑战。为了满足这些约束，使用商用低功耗现场可编程门阵列（FPGA），设计并实现了定制的径迹数据获取（TDAQ）板和固件。本文论述了TDAQ单元的设计特点，使径迹探测器能够高效运行，并特别关注功耗性能。
