  • Compact dual ion composition instrument
    Patent number: 9613789
    Abstract: A relatively compact dual ion composition instrument and associated methodology for measuring plasma and ion populations in a variety of interplanetary and planetary environments. The unitary device can measure mass and ionic charge state compositions and 3D velocity distributions of 10 eV/q to 40 keV/q plasma and pick-up ions; and (2) mass composition, energy spectra and angular distributions of 30 keV to 10 MeV energetic ions.

  • Spectrograph time of flight system for low energy neutral particles
    Patent number: 7115861
    Abstract: A mass spectrometer is provided for identifying mass and velocity distributions in a continuous ion beam is configured with a circular dispersive system creating a rotating electromagnetic field, which is capable of deflecting the ion beam from an initial direction, and a circular position-sensitive detector intercepting the deflected ion beam and providing information from which the ion mass-per-charge ratio is determined
