GAS MIXTURE ANALYZING DEVICE Russian patent published in 2006 - IPC H01J49/28 

FIELD: plasma investigations and mass-spectrometry.

SUBSTANCE: proposed device has gas mixture ionizer with ion-optic system, stigmatically focused mass-spectrometer, solid-state converter, electrostatic analyzer, and recording unit, all arranged in tandem along motion direction of particles. Converter is made of ultra-thin diamond-like foil disposed at 45 deg. to motion direction of particles and in same plane as one of plates of electrostatic analyzer made in the form of flat capacitor. Converter is enclosed by cylinder to form combined Faraday cylinder whose axis coincides with motion direction of particles; cylinder, converter, and electrostatic analyzer plate are electrically insulated from one another; input of charged-particles recorder is disposed in same electrostatic analyzer plate as converter. Charged-particles converter can be made in the form of amplifier on microchannel strip or in the form of set of secondary electronic multipliers.

EFFECT: ability of analyzing hydrogen-helium mixture with high definition of atoms having close values of mass-to-charge ratio.
