Abstract
Satellites orbiting within the magnetospheres of the giant planets are effective absorbers of trapped radiation, forming the characteristic and dominant structure of the radiation belts. The study of satellite absorption signatures observed by charged particle detectors involves simulating the detector response to particle distributions that include the effects of the time- and longitude-dependent absorption, guiding center drifts, and diffusion. The calculations are most easily carried out by separating solutions of the transport equation into time-dependent and -independent parts, that typically lead to small and large scale features called micro- and macro- signatures respectively. In this paper, methods for calculating the two types of signatures are described, and applied to the case of electron absorption by Saturn's satellite Mimas. The results are compared with data from Pioneer 11 and Voyager 2.

The idea of further investigating the interpretation of the Mimas microsignatures was suggested to me by Chris Goertz during fruitful discussions that we had on this subject.
