AB: Since July 2004 the Cassini spacecraft is in orbit around Saturn providing in-situ measurements of the Saturnian magnetosphere. Several magnetospheric regions could be identified including the intense radiation belts and ring current regions in the inner magnetosphere as well as the equatorial plasma sheet and the regions close to the outer boundaries of the magnetosphere from which the global structure as well as the dynamic of the Kronian magnetosphere can be studied. Using the energetic particle measurements from the MIMI instrument as well as the magnetic field measurements from the MAG instrument onboard Cassini we will discuss the derived pitch angle distributions, electron and ion energy spectra and periodicities in magnetic field components and particle parameters in various regions. Some of the results are (1) asymmetry in the particle fluxes between the day and night sector at comparable distances; (2) highly varying particle fluxes as a consequence of large-scale dynamic processes in the equatorial plasma sheet; (3) field-aligned bi-directional electron fluxes in the outer part of the Kronian magnetosphere with correlation to the Saturnian aurora; (4) variations of the magnetic field components and electron fluxes with the planetary rotation period pointing to a magnetic anomaly inside the planet or pointing to corotating structures in the Saturnian magnetotail; (5) injections and corotating structures in Saturn's magnetotail as a consequence of dynamical processes.
