The Galileo Plasma Wave Receiver is described by Gurnett et al., 1992 [GURNETTETAL1992] which is provided in the DOCUMENT/PWS/INSTdirectory of the PDS/PPI data archive volumes.
Scientific Objectives:
The basic objective of this investigation is the study of plasmawaves and radio emissions in the magnetosphere of Jupiter. TheVoyager 1 and 2 flybys of Jupiter have now clearly shown that manycomplex types of plasma wave and radio-emission phenomena occur in theJovian magnetosphere. These include electromagnetic whistler modeemissions called chorus and hiss, electromagnetic continuum radiationtrapped in the magnetospheric cavity, electrostatic waves associatedwith harmonics of the electron cyclotron frequency, and a wide varietyof escaping radio emissions. Some of these waves, such as the whistlermode emissions, are believed to play an important role in the dynamicsof the magnetosphere by controlling the pitch-angle scattering and lossof energetic charged particles. In other cases plasma waves provide animportant diagnostic tool by revealing various characteristicfrequencies of the plasma, from which quantities such as the electrondensity can be computed.
