| 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.
