摘　　要：小型化、高集成化是深空探测载荷发展的主要趋势。在我国自主火星探测计划中,设计了一种高集成化的火星离子与中性粒子分析仪。采用从传感器到电子学进行最大限度共用的设计思路,在一台仪器中实现对离子和能量中性原子进行能量、方向和成分的探测,大大降低了仪器对卫星平台的资源需求。仪器采取静电分析进行离子的方向和能量测量、采取飞行时间方法进行离子成分的测量。中性原子采用电离板电离成带电离子,后端的能量测量和成分测量与离子相同。鉴定件样机已经完成了初步的测试定标,结果表明其满足设计要求。The miniature and integrated design is a main trend in science payload development for deep space. An integrated ion and neutral particle analyzer is built for Chinese Mars exploration project. The measurements of ion and energetic neutral atom share the sensor and electronics and are integrated in a single instrument with lower mass and power. Electrostatic analyzing method is used to measure the ions’ energy and direction. Time of flight method is used to measure the ions species. The energetic neutral atoms are ionized firstly and the same measurement method with ions. The qualification model is calibrated and the results fulfill the requirements for the Mars project.
