Wide-angle Compact Ion and Neutral Mass Spectrometer and Energy Analyzer

We propose to combine the traditional plasma analyzer with a gated TOF ion and neutral mass spectrometer to enable a full characterization of the ion distribution function, total ion and neutral density, ion and neutral composition, ion temperature and drifts, and neutral winds (when augmented with the Optical Angular Resolution Front End developed through a parallel IRAD). The development of this highly adaptable and compact spectrometer with energy analysis directly supports proposals to ROSES HTIDES (1), SIMPLEX (1), and Explorer-Mission of Opportunity (2).

A laboratory prototype will be developed, including all of the critical sensor and electronics components from INMS, with added capabilities including higher max energy for scanning, increased mass resolution, and FOV deflectors.
