In order to obtain ISS spectra, the backscattered primary ions are sampled by which of the following?

(a) Faraday cup analyser

(b) Photographic analyser

(c) Micro-channel analyser

(d) Cylindrical mirror analyser

This question was posed to me in a job interview.

My doubt stems from Instrumentation of Ion Spectroscopy topic in chapter Electron and Ion Spectrometers of Analytical Instrumentation
