MMS 2 Electric Particle Detector, Fly's Eye Energetic Particle Sensor (EPD, FEEPS) Electrons, Level 2 (L2), Burst Mode, 0.3025 s Data

Fly's Eye Electron Proton Spectrometer (FEEPS) Burst Data. The Energetic Particle Detector (EPD) investigation aboard the four MMS spacecraft consists of two instrument designs, the FEEPS and the EIS (Energetic Ion Spectrometer). A FEEPS consists of six Heads, each composed of two Eyes. Each eye is a particle telescope with a single silicon detector. There are nine electron eyes and three ion eyes per FEEPS. The energy coverage is from 25 keV to 650 keV for electrons and 45 keV to 650 keV for ions. Each eye has sixteen energy channels, the spacing of which can be modified by command. The fields of view and pointing of each eye are designed to provide a broad, instantaneous field of view for the twelve eyes per FEEPS.

复眼式电子质子能谱仪（Fly's Eye Electron Proton Spectrometer，FEEPS）爆发数据。搭载于4颗MMS航天器的高能粒子探测器（Energetic Particle Detector，EPD）探测系统包含两种仪器构型：复眼式电子质子能谱仪（FEEPS）与高能离子能谱仪（Energetic Ion Spectrometer，EIS）。每台FEEPS包含6个探测头，每个探测头由两个探测眼组成。每个探测眼均为搭载单硅探测器的粒子望远镜。每台FEEPS配备9个电子探测眼与3个离子探测眼。电子的能量覆盖范围为25 keV至650 keV，离子的能量覆盖范围为45 keV至650 keV。每个探测眼拥有16个能量通道，其通道间距可通过地面指令调整。各探测眼的视场与指向均经过设计，可为单台FEEPS搭载的12个探测眼提供宽广的瞬时视场。
