        "Description": "Energetic Ion Spectrometer (EIS): EIS uses a time-of-flight/pulse-height sensor to provide ion composition measurements (protons vs. oxygen ions) and angular distributions over the energy range ~45 keV to 500 keV and with a temporal resolution of 30 s. EIS development is led by Co-I B. H. Mauk (Applied Physics Laboratory), who also heads the Energetic Particle investigation as a whole.",
