  • Radiation shield
    Patent number: 10755827
    Abstract: An apparatus for radiation shielding is provided. The apparatus includes a first housing element and a first plurality of magnetic elements arranged in a first array on the first housing element. The first array is configured to generate a first tapered magnetic field and, using the first tapered magnetic field, deflect incoming radiation away from a protected element.

  • Space ion analyzer with mass spectrometer on a chip (MSOC) using floating MSOC voltages
    Patent number: 10319572
    Abstract: A space ion analyzer in a spacecraft includes an axis and an aperture to receive an ion stream. An ion focuser to focus the ion stream along the axis responsive to a focus voltage, and an ion deflector deflects ions from the axis based on energies of the ions and a deflector voltage difference applied across plates of the ion deflector. A mass spectrometer on a chip (MSOC) directs ions from the ion deflector to an ion detector array responsive to an MSOC voltage difference applied to the MSOC. A focus voltage generator generates the focus voltage as a variable voltage referenced to a spacecraft ground. A deflector voltage generator generates the deflector voltage difference with a controllable magnitude and referenced to the spacecraft ground. An MSOC voltage generator generates the MSOC voltage difference with a controllable magnitude and referenced to a breaking potential controllable relative to the spacecraft ground.
