This experiment measured charged-particle composition and spectra using four detector systems: (1) the main telescope, consisting of seven elements and providing energy spectra (approximately 3 to 68 MeV for protons and 10 to 150 MeV/nucleon for oxygen), element resolution (through oxygen), and isotope resolution (for H and He); (2) the low-energy subsystem telescope, consisting of two elements and using a very small thin first element to extend the high-sensitivity proton measurements below 1 MeV (0.3 to 9 MeV) in the presence of a high gamma-ray background aboard the spacecraft; (3) the electron-current detector (ECG), consisting of a beryllium-shield silicon detector operated in current mode to measure high fluxes of electrons with energies above 3 MeV; and (4) the fission cell detector, recording fission fragments from the nucleon-induced fission of thorium 232 sandwiched between two large-area silicon detectors to measure fluxes of protons (above 30 MeV) in the presence of high fluxes of electrons. The experiment sample time was synchronized with the spacecraft spin, permitting sectoring of the readout of the main and low-energy telescopes into eight octants about the spin axis. Data also include the interplanetary region.

Instrument Overview
  ===================
    The charged particle detector had four measuring systems: two
    particle telescopes that operated in interplanetary space, and two
    that measured the intense trapped electrons and protons inside the
    Jovian radiation belts.
 
    During the interplanetary phase of the mission, before and after
    encounter with Jupiter, the experiment sought to identify the
    chemical elements hydrogen, helium, lithium, beryllium, boron,
    carbon, and nitrogen, and to separate hydrogen, deuterium, helium-3
    and helium-4 in an attempt to differentiate between particles coming
    from the Sun and those from the Galaxy. The instrument was also used
    to determine how the streams of high energy particles from the Sun
    travel through interplanetary space. The main telescope of seven
    solid-state detectors measured the composition of cosmic rays from 1
    to 500 million electron volts (MeV), and a three-element, low
    energy telescope measures 0.4 to 10 MeV protons and helium nuclei.
 
    Two types of sensors were used to cope with the extremely high
    intensities of trapped radiation in the magnetosphere of Jupiter. A
    solid-state electron current detector, operating below -40
    degrees C, was designed to detect those electrons above 3 MeV that
    generate the decimetric radio waves emitted from Jupiter. A trapped
    proton detector contains a foil of thorium which undergoes nuclear
    fission when impacted with protons above 30 MeV, but is insensitive
    to electrons.
