1. The current of each ion beam is then measured using a'Faraday cup 'or multiplier detector. 2. Some Faraday cup assemblies include a phosphor screen as well. 3. In a metal housing ( Faraday cup ) a particle filter is mounted on an insulator. 4. C _ F-capacity of Faraday cup . 5. Faraday cups are used e . g . in mass spectrometers being an alternative to secondary electron multipliers.6. A Faraday cup is a detector that measures the current in a beam of charged ( aerosol ) particles. 7. Signal from R _ F is the Faraday cup I-V characteristic which can be observed and memorized by oscilloscope 8. Typically, some type of electron multiplier is used, though other detectors including Faraday cups and ion-to-photon detectors are also used. 9. The signal from R _ F enables an observer to acquire an I-V characteristic of the Faraday cup by oscilloscope. 10. The advantage of the Faraday cup is its robustness and the possibility to measure the ion or electron stream absolutely.
