Strumentazione ed Esperimenti per Campi, Particelle e Onde:
Ion & Neutral Mass Spectrometer (INMS)
Team Leader: Dr. J. Hunter Waite
INMS General Description:
The Ion and Neutral Mass Spectrometer (INMS) is intended to
measure positive ion and neutral species composition and structure
in the upper atmosphere of Titan and magnetosphere of Saturn,
and to measure the positive ion and neutral environments of Saturn's
icy satellites and rings.
INMS Scientific Objectives:
To measure ion and neutral species composition and structure
in the upper atmosphere of Titan.
To study Titan atmospheric chemistry.
To investigate the interaction of Titan upper atmosphere
with the magnetosphere and solar wind.
To measure ion and neutral species compositions during ring
plane crossings and icy satellite flybys.
INMS Sensing Instruments:
Closed source (neutrals only) and open source (ion and neutrals)
Lens System
Quadrupole Mass Analyzer and Detector, 1-99 amu
INMS Instrument Characteristics:
Mass (current best estimate) = 9.25 kg
Average Operating Power (current best estimate) = 27.70 W
Average Data Rate (current best estimate) = 1.50 kilobits/s
