Title: Low energy charged particles at Saturn

Journal Article · · Johns Hopkins APL Technical Journal; (United States)
OSTI ID:5022439

The Low Energy Charged Particle (LECP) experiment measures charged particles with energies greater than about 20 kiloelectron volts and can provide information about the chemical composition of the particles. In addition, the instrument scans through a full 360 deg and is thus the only detector on board Voyager capable of determining actual flow anisotropies of charged particles. An overview of representative particle data from the Saturn encounter is shown in a graph. The LECP instrumentation was able to measure perturbations in the corotational flow of plasma caused by the relative motion of Titan. The composition of the Saturnian magnetosphere is particularly interesting. At energies sampled by the LECP detectors, nearly all the ions are protons. The proton to helium ratio can be as large as 5000:1 and is larger than that seen in any other magnetosphere. The large ratio suggests that plasma within Saturn's magnetosphere does not originate within Saturn's magnetosphere.
