ABSTRACT
This study presents an analysis of long lasting (~2-3 hours) energetic (>~60 keV) ion and (>~40 keV) electron events observed by the HISCALE instrumentation on board Ulysses in the high latitude Jovian magnetosphere. The HISCALE data are consistent with: (1) the existence of large scale layers of energetic ions and electrons in the high latitude Jovian magnetosphere and (2) the quasi-periodic (~40 min) emissions of energetic particles from the poles as the primary source of these layers. The proposed concept of the high latitude magnetospheric large scale energetic particle layers provide us with the possibility of a new synthesis of a variety of Jovian observations.
