Interplanetary Monitoring Platform (IMP-8) Low-Energy Proton and Electron Differential Energy Analyzer (LEPEDEA) Data

[ Get Data ]

Abstract: IMP-8 (IMP-J) was launched by NASA on October 26, 1973 to measure the
magnetic fields, plasmas, and energetic charged particles (e.g.,
cosmic rays) of the Earth's magnetotail and magnetosheath and of the
near-Earth solar wind. IMP-8 continues to operate.

These experiments were designed to measure the energy spectra of
low-energy electrons and protons in the geocentric range of 30 to 40
