太阳、异常和磁层粒子探测器（SAMPEX）上的质子/电子望远镜（PET）旨在提供来自太阳、银河和磁层源的高能电子和轻核的测量。PET是一种全固态系统，其将测量从大约1到大约30 MeV/核子的电子以及从大约20到大约300 MeV/核子的H和He核的微分能谱，其中H和He的同位素分辨率从大约20扩展到大约80 MeV/核子。由于SAMPEX在其近极轨道上扫描所有当地时间和地磁截止点，PET将描述太阳活动下降期间沉淀的相对论电子事件，并将检查沉淀电子在中层大气中产生奇数氮和氢分子的速度是否足以影响O/sub 3/耗尽。此外，PET将通过提供H、He和电子的测量，补充SAMPEX上对高能重（Z>2）核的元素和同位素组成的研究。最后，PET从潜在的自然和人造来源中识别高能正电子的能力有限。>

The proton/electron telescope (PET) on SAMPEX (Solar, Anomalous, and Magnetospheric Particle Explorer) is designed to provide measurements of energetic electrons and light nuclei from solar, Galactic, and magnetospheric sources. PET is an all solid-state system that will measure the differential energy spectra of electrons from approximately 1 to approximately 30 MeV and H and He nuclei from approximately 20 to approximately 300 MeV/nucleon, with isotope resolution of H and He extending from approximately 20 to approximately 80 MeV/nucleon. As SAMPEX scans all local times and geomagnetic cutoffs over the course of its near-polar orbit, PET will characterize precipitating relativistic electron events during periods of declining solar activity, and it will examine whether the production rate of odd nitrogen and hydrogen molecules in the middle atmosphere by precipitating electrons is sufficient to affect O/sub 3/ depletion. In addition, PET will complement studies of the elemental and isotopic composition of energetic heavy (Z>2) nuclei on SAMPEX by providing measurements of H, He, and electrons. Finally, PET has limited capability to identify energetic positrons from potential natural and man-made sources. >
