Voyager 2 Plasma Spectrometer (PLS) Faraday Cups A-D Low Energy Resolution Current Ion Spectra, L Mode, for Proton Energies from 10 eV to 5950 eV, 96 s Data

These Ion Current Spectra in the Jovian Magnetosphere are from the Plasma Spectrometer (PLS) Instrument on Voyager 2 during July 1979 Flyby of Jupiter. The Instrument has four Faraday Cups A, B, C, and D, the Electron Data come only from Faraday Cup D. The Data are specified in Terms of Current per Faraday Cup in femto-amperes (10^-15 A equals 1 fA) versus Channel Number and Energy (eV). This Data Set is for the PLS L Mode covering Proton (H+ Ion) Energies from 10 eV to 5950 eV at Low Energy Resolution in 16 logarithmic Energy Channels. The PLS Instrument samples only one Mode of Electron (E1, E2) or Ion (L, M) Spectra in each Time Interval, so the L Mode Data are not continuous but consecutive with the other Modes in Time.

GIOTTO ION MASS SPECTROMETER HIGH ENERGY RANGE DATA V1.0

A wide range of ion species and velocity distributions are expected to be found as the Giotto spacecraft traverses the coma of Halley's Comet. The outer coma is characterized by the interaction between solar wind and cometary plasmas, the inner coma by the outflow of cometary neutrals and their ionization products. The resultant demands on instrument dynamic range preclude use of a single sensor for measurements of ion composition. The Giotto Ion Mass Spectrometer (IMS) therefore consists of two sensors: one optimized for the outer and the other for the inner coma, with each obtaining complementary information in the region for which it is not optimized. Both sensors feature mass imaging characteristics, thereby permitting simultaneous measurements of several ion species by means of multi-detector arrays. The prime objective of the High-Energy Range Spectrometer (HERS) is to measure the ion abundances and three-dimensional velocity distributions outside the cometary contact surface.

ACE Ultra Low Energy Isotope Spectrometer (ULEIS) Ion Fluxes, Level 2, Hourly Data

The Ultra Low Energy Isotope Spectrometer measures Ion Fluxes over the Charge Range from H through Ni from about 20 keV/nucleon to 10 MeV/nucleon, thus covering both Suprathermal and Energetic Particle Energy Ranges. Exploratory Measurements of Ultra-Heavy Species (Mass Range above Ni) will also be performed in a more limited Energy Range near 0.5 MeV/nucleon. ULEIS will be studying the Elemental and Isotopic Composition of Solar Energetic Particles, and the Mechanisms by which these Particles are energized in the Solar Corona. ULEIS will also investigate Mechanisms by which Supersonic Interplanetary Shock Waves energize Ions. To avoid Confusion and Misunderstanding, it is recommended that Users consult with the appropriate ACE Team Members before publishing Work derived from the Data. The ACE Team has worked hard to ensure that the Level 2 Data are free from Errors, but the Team cannot accept Responsibility for Erroneous Data, or for Misunderstandings about how the Data may be used. This is especially true if the appropriate ACE Team Members are not consulted before Publication. At the very least, Preprints should be forwarded to the ACE Team before Publication.

AMPTE-CCE Medium Energy Particle Analyzer (MEPA), Energetic Particles, H0, 0.1875 s Data

This dataset contains high time resolution MEPA rate channel data. MEPA is a particle telescope with an ION head and a TOF head. The TOF head can measure species and energy, while the ION head only measures the energy of the ions, which are mostly protons. In fact, the counts in the ION head are all assumed to be protons up to 1830 keV. The ION head has 10 energy channels, and so the first 8 channels, that are all below 1830 keV, are assumed to be all protons, and the 2 channels above this are assumed to be all alphas. The TOF head has 9 energy channels that are generic, ions of any species are counted, and some species specific channels for protons, helium, oxygen, and iron. The AMPTE data was divided into records, with each record holding data from 4 spins. In any record, all the TOF species channels are always present, but only one of either a, the 10 ION head channels or b, 9 TOF generic channels are present. The majority of records have the ION head channels. The AMPTE spacecraft had a spin period of about 6 seconds. The exact spin period varies slightly and is included in the data. MEPA data is sectored into 32 directions per spin. Nearly all channels are reported as sectored values, but to conserve telemetry, many channels are only read out every other spin, or every fourth spin. In this data, all values are summed so that they are reported every fourth spin. Note that in the original AMPTE datesets, there was a timing problem which required that 19.75 seconds, one Major Frame of telemetry, be added to time values extracted from the processing system. This correction has already been made in the particle data in this dataset.
