FIELD: physics.
SUBSTANCE: detecting apparatus detects a first part of a beam of charged particles and generates a first output signal based on intensity of the detected first part of the beam of charged particles. The detecting apparatus detects a second part of the beam of charged particles which has traversed a longer trajectory section through a mass-spectrometer than the first part of the beam of charged particles, and generates a second output signal based on the detected second part of the beam of charged particles. A controller controls parameters of the beam of charged particles and (or) detecting apparatus based on the first output signal of the detecting apparatus, so as to control the second output signal of the detecting apparatus.
EFFECT: high mass resolution.
