      <Description>The objective of experiment (E6) was to study high-energy, charged,
          cosmic-ray particles of solar, planetary, and galactic origin in
          interplanetary space. Protons and alpha particles with
          eneries &gt;1.3 MeV/nucleon, and electrons &gt;0.3 MeV were measured within
          interplanetary space over the range from 0.3 to 1.0 AU. The instrument, a
          particle telescope with 55-deg field of view, consisted of five semiconductor
          detectors, one sapphire Cherenkov counter, and one scintillation counter, all
          enclosed by an anticoincidence cylinder. The telescope was calibrated prior to
          launch using radioactive sources, particle accelerators, and ground-level muons.
          It measured protons and alpha particles in six channels (1.3-3.3, 3.3-13,
          13-27, 27-37, 37-45, and &gt;45 MeV/nucleon) and electrons in five energy
          channels (0.3-0.8, 0.8-2, 2-3, 3-4, and &gt;4 MeV). For more detail see
          pp.253-257 of Raumfahrtforschung, v.19, n. 5, 1975.
