For charging investigations around Jupiter and Saturn, a description of the plasma environment has been described by Garrett and Hoffman [RD.11]. This describes the environments as either a Maxwellian distribution or a Kappa distribution or a sum of the two, as follows
Maxwellian:
|
|
(H-3) |
Kappa:
|
|
(H-4) |
where
Γ is the Gamma Function.
[RD.11] lists appropriate parameters for various regions in the magnetospheres of Jupiter and Saturn.
Worst-case plasma parameters, i.e. corresponding to the highest calculated charging level in eclipse in [RD.11], are given in Table H-8.
