  • Method And Apparatus To Enhance Output Current Linearity In Tandem Electron Multipliers
    Publication number: 20140265829
    Abstract: A tandem electron multiplier device includes an input end position electron multiplier generating an electron emission; an output end position electron multiplier receiving the electron emission and generating an output electron emission; an electron collector to receive the output electron emission; a power supply; and an electrical biasing network coupled to the power supply, the electrical biasing network supplying voltages to connections at the input end position electron multiplier and the output end position electron multiplier, the voltages supplied to provide output current linearly with respect to input current across the tandem electron multiplier device.

  • Tandem continuous channel electron multiplier
    Patent number: 7687978
    Abstract: A channel electron multiplier including a single channel CEM for receiving an input particle. A multi-channel CEM is positioned after the single channel CEM for receiving emissions from the single channel CEM. An electron collector is positioned after the multi-channel CEM for generating a pulse current in response to emissions from the multi-channel CEM.

  • Ion detection system with neutral noise suppression
    Patent number: 7465919
    Abstract: An ion detection system includes a mass analyzer generating an ion beam along an ion beam longitudinal axis. A field generator generates a field for altering the direction of ions in the ion beam away from the ion beam longitudinal axis. A conversion dynode includes an ion collision region on a conversion dynode surface. A conversion dynode axis passes through the ion collision region perpendicular to the conversion dynode surface, the conversion dynode axis being offset from and not intersecting the ion beam longitudinal axis. An electron multiplier receives secondary charged particles from the conversion dynode generated in response to the ion collision with the conversion dynode surface.
