1. Following the central region of the Saturnian nightside plasma sheet
Master-uppsats, Uppsala universitet/Rymd- och plasmafysikSammanfattning : We use magnetic field data from Cassini’s on board magnetometer (MAG), plasma measurements by Cassini Plasma Spectrometer (CAPS) and electron density measurements from the RPWS Langmuir probe (LP) on board Cassini, for an extended set of orbits from 2004 to 2010 and for distances up to 30 Rs from the planet. The central region of the nightside plasma sheet is identified using the radial component of the magnetic field Br, in contrary to solely geometrical criteria used in previous studies, such as the vertical distance z from the equatorial plane.

2. Energetic O+ ions upstream from the Saturnian bow shock, measured by Cassini
L3-uppsats, Institutionen för fysik och astronomi; Institutet för rymdfysik, UppsalaavdelningenSammanfattning : We use particle and magnetic field data from the Ion and Neutral Camera (INCA) and the magnetometer (MAG) onboard Cassini to detect and examine an energetic particle event that occurred upstream from the Saturnian bow shock during DOY 229/2007. The energetic (>100 keV) O+ ions are observed only when the Interplanetary Magnetic Field (IMF) connects the spacecraft with the planetary bow shock. LÄS MER
