摘要 阻滞势分析仪(RPA)可有效获得等离子体离子能量分布,针对空间电推力器产生的交换电荷等离子体羽流参数范围与特性,开展了专用RPA的设计,着重描述已用于航天器上搭载的RPA设计方法及影响因素分析。在轨测试表明,所设计RPA获得了理想的测试结果,通过对测试数据分析获得了羽流等离子体的离子能谱和束流密度。 Plasma ion energy per unit charge distribution can be measured effectively by Retarding Potential Analyzer ( RPA ). RPA should be designed specially according to plume plasma parameters range and feature of the Xe thruster. Major principles usable for good RPA design are discussed carefully. Design and the influence factors of RPA being used for on orbit spacecraft are described. On-orbit testing results show that desired data were achieved by the RPA. The data achieved by RPA are given and analyzed.
