Data Set Abstract |
As its name implies, the Cosmic Ray
Subsystem (CRS) was designed for cosmic ray studies.
It consists of two high Energy Telescopes (HET), four Low Energy
Telescopes (LET) and The Electron Telescope (TET). The detectors have
large geometric factors (~ 0.48 to 8 cm^2 ster) and long
electronic time constants (~ 24 [micro]sec) for low power
consumption and good stability. Normally, the data are
primarily derived from comprehensive ([Delta]E[1], [Delta]E[2]
and E) pulse-height information about individual events.
Because of the high particle fluxes encountered at Jupiter and
Saturn, greater reliance had to be placed on counting rates in
single detectors and various coincidence rates. In inter-
planetary space, guard counters are placed in anticoincidence
with the primary detectors to reduce the background from
high-energy particles penetrating through the sides of the
telescopes. These guard counters were turned off in the Jovian
magnetosphere when the accidental anticoincidence rate became
high enough to block a substantial fraction of the desired
counts. Fortunately, under these conditions the spectra were
sufficiently soft that the background, due to penetrating
particles, was small. |
