Voyager Cosmic Ray Subsystem (CRS)
The CRS looks only for very energetic particles in plasma, and has the
highest sensitivity of the three particle detectors. Very energetic
particles can often be found in the intense radiation fields surrounding
some planets (like Jupiter). Particles with the highest-known energies
come from other stars. The CRS looks for both.
The CRS makes no attempt to slow or capture the super-energetic particles.
They simply pass completely through the CRS. However, in passing through,
the particles leave signs that they were there.

Cosmic Ray Experiment
To measure the energy spectrum of electrons from 3 - 110 MeV.
To measure the energy spectra and elemental composition of all cosmic
ray nuclei from hydrogen through iron over an energy range from
approximately 1 - 500MeV/nuc.
To provide information on the energy content, origin, acceleration
process, life history, and dynamics of cosmic rays in the galaxy, and
contribute to an understanding of the nucleosynthesis of elements in
cosmic ray sources.
To provide information on the transport of cosmic rays, Jovian
electrons, and low energy interplanetary particles over an extended
region of interplanetary space.
To measure the three-dimentional streaming patterns of nuclei from
Hydrogen through Iron and electrons over an extended range.
To measure particle charge compostion in the magnetosphere of
Jupiter, Saturn, Uranus, and Neptune.
