(a) Faraday cup collector

(b) Channeltron

(c) Micro-channel plate

(d) Electron multiplier transducer

This question was posed to me in unit test.

I need to ask this question from Ion Transducers in section Mass Spectrometer of Analytical Instrumentation

Answer 1

Correct option is (d) Electron multiplier transducer

For explanation: Electron multiplier transducer is similar to photo multiplier transducer. The difference is that its primary cathode detects ions rather than photons.
