Scientific paper

The cosmic ray experiment instrument aboard Voyager 2 which measured the electron fluxes in the middle magnetosphere of Uranus is described along with the analysis procedure used to model the electron intensity spectrum. Model fits are presented to the differential intensity spectra from observations between L values of 6 and 15. The spectra are well represented by power laws in kinetic energy with spectral indices between five and seven. The phase space density at fixed values of the first two adiabatic invariants generally increases with L, indicating an external source. However, there are also local minima associated with Ariel and Umbriel, indicating either a local source or an effective source due to nonconservation of the first two adiabatic invariants. For electrons which mirror at the highest magnetic latitudes, the local minimum associated with Ariel is radially displaced from the minimum L of that satellite by about 0.5.
