= Faraday cup
{wiki=Faraday_cup}
A Faraday cup is a device used in various fields of physics and engineering, particularly in the study of charged particles and electron beams. Named after the scientist Michael Faraday, it serves as a tool for measuring the current of charged particles, such as electrons or ions, by collecting them and allowing for the measurement of the charge. The basic structure of a Faraday cup consists of a conductive cup or chamber that can capture and hold charged particles.
