UVIS/HDAC Lyman-α observations of the geocorona during Cassini’s Earth swingby compared to model predictions

Keller, H. U.; Werner, S.; Korth, A. +1 more

The Hydrogen Deuterium Absorption Cell (HDAC) is part of the Ultraviolet Imaging Spectrograph (UVIS) experiment aboard the Cassini spacecraft. During Cassini's Earth swingby on August 18, 1999, HDAC was used as a photometer to measure solar Lyman-α radiation scattered by the neutral hydrogen atoms of the geocorona. These data provide information a…

Monte Carlo simulations of CASSINI/LEMMS

Livi, S.; Haggerty, D. K.

In an effort to characterize the response of the low energy magnetospheric measurements system (LEMMS) on the CASSINI spacecraft to energetic ions and electrons we have taken advantage of the excellent pre-launch beam calibrations in comparison to an extensive series of electron and ion Monte Carlo simulations. We selected the geometry and trackin…
