Faraday cup
From Mass Spec Terms
| DRAFT DEFINITION |
| Faraday cup |
|---|
|
A hollow collector, open at one end and closed at the other, used to measure the ion current associated with an ion-beam. On arrival at the earthed metal plate the ions are neutralized either by accepting or donating electrons. A small electric current is produced which can be amplified. The device whilst simple and robust is not sensitive. |
| Considered between 2004 and 2006 but not included in the 2006 PAC submission |
