  • Apparatus operating with contact ionization for the production of a beam of accelerated ions
    Patent number: 4983845
    Abstract: An apparatus operating by contact ionization for the production of a beam of accelerated ions comprises an ionization electrode (1) in the form of a small tube, which forms a duct, the inside of which is used for contact ionization of the atoms for ionization, and which has capillary dimensions at least adjacent its exit, which is situated opposite an acceleration electrode (3).

  • Double-focussing mass spectrometer
    Patent number: 3949221
    Abstract: A double-focussing mass spectrometer having an electrostatic field energy alyser followed by a magnetic field momentum analyser. The entrance diaphragm is essentially annular and thus the entrance aperture of the spectrometer defines a hollow cone with its apex at the ion source. The number of ions received per second by such an aperture is significantly larger than for a conventional spectrometer entrance aperture.
