| Faraday cup | A faraday cup is a metal (conductive) cup meant to recatch secondary particles. (SeeBlack body#Details). When a package of ions hits the metal it will be charged while the ions are neutralized. The metal can then be discharged to measure a small current equivalent to the number of discharged ions. Essentially the faraday cup is part of a circuit where ions in the gas phase act as charge carriers during part of the circuit and the faraday cup is the interface to the solid phase where electrons act as the charge carriers (as in most circuits). By measuring the electrical current (the number of electrons flowing through the circuit per second) on the metal part of the circuit the number of charges being carried by the ions in the gas phase part of the circuit can be determined.

| Faraday cup detector | Meteorology & Standards | Used as a primary standard for measuring beams of charged particles. The beam falls on an electrode sufficiently massive to stop the beam as well as almost all the secondary particles resulting when the beam strikes the cup. This electrode is electrically insulated from its surroundings, so that the electric charge carried to it by the beam can be measured. Source: European Union. (references) | |
