FIELD: analysis of beam of charged particles. SUBSTANCE: analyzed beam is passed many times through high-frequency system (duant) and particles are separated in magnetic field thanks to frequency difference of reversion of ions and high-frequency electric field. Mass spectrometer has electromagnet with magnetic field sector-focussed in both planes, arc ion source of open type, high-frequency system (duant) with definite angular extent. EFFECT: improved efficiency of identification of chemical, element and isotopic composition of substance, measurement of masses of atomic nuclei. 3 dwg
