  • Dual-detection residual gas analyzer
    Patent number: 8916822
    Abstract: A detector in a residual gas analyzer (RGA) is configured to receive ions traveling in a downstream direction along a beamline and includes a steering electrode offset from the beamline. A first ion-receiving electrode is at least partly on the opposite side of the steering electrode from the beamline. A second ion-receiving electrode is at least partly offset from the beamline, at least partly across the beamline from at least a portion of the steering electrode, and at least partially upstream of at least a portion of the steering electrode. A shielding electrode is arranged at least partly between the beamline and the second ion-receiving electrode. A source applies a potential to the shielding electrode. A residual gas analyzer (RGA) includes an ion source, an analyzer, and such a detector.
