The resulting current can be measured and used to determine the number of ions or electrons hitting the cup. [1] The Faraday cup is named after Michael Faraday who first theorized ions around 1830. 1 How it works 2 Error sources 3 See also 4 References 5 External links When a beam or packet of Ions hits the metal it gains a small net charge while the ions are neutralized. The metal can then be discharged to measure a small current equivalent to the number of impinging ions. Essentially the faraday cup is part of a circuit where ions are the charge carriers in vacuum and the faraday cup is the interface to the solid metal where electrons act as the charge carriers (as in most circuits).
