Faraday Cup

Faraday cups are used for measuring the electrical current of a charged particle beams in real time and independent of the pressure. Our systems are suitable down to ultra-high vacuum conditions. They can be used for measuring the electrical current of an electron or ion beam in the range of fA and pA up to mA and are suitable for beam power loads of up to 200 W and beyond. A suppressor electrode is built in by standard for compensating the secondary electron emission, increasing the measurement precision in the process.
