| Abstract: | The Rosetta dual Langmuir probe instrument, LAP, utilizes the multiple powers of a pair of spherical Langmuir probes for measurements
of basic plasma parameters with the aim of providing detailed knowledge of the outgassing, ionization, and subsequent plasma
processes around the Rosetta target comet. The fundamental plasma properties to be studied are the plasma density, the electron
temperature, and the plasma flow velocity. However, study of electric fields up to 8 kHz, plasma density fluctuations, spacecraft
potential, integrated UV flux, and dust impacts is also possible. LAP is fully integrated in the Rosetta Plasma Consortium
(RPC), the instruments of which together provide a comprehensive characterization of the cometary plasma.
The LAP Team is listed in Table III. |
