The Relativistic Electron-Proton Telescope (REPT) instruments were designed to measure ∼2 to >18 MeV electrons and ∼18 to > 115 MeV protons as part of the science payloads onboard the dual Radiation Belt Storm Probes (RBSP) spacecraft. The REPT instruments were turned on and configured in their science acquisition modes about 2 days after the RBSP launch on 30 August 2012. The REPT-A and REPT-B instruments both operated flawlessly until mission cessation in 2019. This paper reviews briefly the REPT instrument designs, their operational performance, relevant mode changes and trending over the course of the mission, as well as pertinent background effects (and recommended corrections). A substantial part of this paper highlights discoveries and significant advancement of our understanding of physical-processes obtained using REPT data. We do this for energetic electrons primarily in the outer Van Allen belt and for energetic protons in the inner Van Allen zone. The review also describes several ways in which REPT data were employed for important space weather applications. The paper concludes with assessments of ways that REPT data might further be exploited to continue to advance radiation belt studies. The paper also discusses the pressing and critical need for the operational continuation of REPT-like measurements both for science and for space situational awareness.

相对论电子质子望远镜 (REPT) 仪器设计用于测量 ~2 到 >18 MeV 电子和 ~18 到 >115 MeV 质子，作为双辐射带风暴探测器 (RBSP) 航天器上科学有效载荷的一部分。REPT 仪器在 2012 年 8 月 30 日 RBSP 发射后约 2 天打开并配置为科学采集模式。 REPT-A 和 REPT-B 仪器均完美运行，直到 2019 年任务停止。本文简要回顾了 REPT 仪器设计、它们的操作性能、任务过程中的相关模式变化和趋势，以及相关的背景影响（和建议的更正）。本文的很大一部分强调了我们对使用 REPT 数据获得的物理过程的理解的发现和重大进步。我们主要针对外范艾伦带中的高能电子和内范艾伦带中的高能质子执行此操作。该评论还描述了将 REPT 数据用于重要空间天气应用的几种方式。本文最后评估了可以进一步利用 REPT 数据以继续推进辐射带研究的方式。该论文还讨论了在科学和空间态势感知方面对类似 REPT 的测量的操作连续性的紧迫和关键需求。本文最后评估了可以进一步利用 REPT 数据以继续推进辐射带研究的方式。该论文还讨论了在科学和空间态势感知方面对类似 REPT 的测量的操作连续性的紧迫和关键需求。本文最后评估了可以进一步利用 REPT 数据以继续推进辐射带研究的方式。该论文还讨论了在科学和空间态势感知方面对类似 REPT 的测量的操作连续性的紧迫和关键需求。
