The influence of the secondary electrons induced by energetic electrons impacting the Cassini Langmuir probe at Saturn

Gurnett, D. A.; Lewis, G. R.; Coates, A. J. +7 more

The Cassini Langmuir Probe (LP) onboard the Radio and Plasma Wave Science experiment has provided much information about the Saturnian cold plasma environment since the Saturn Orbit Insertion in 2004. A recent analysis revealed that the LP is also sensitive to the energetic electrons (250-450 eV) for negative potentials. These electrons impact the…
