Abstract

The invention relates to electron analysis technology for determining the composition and structure of substances, and more particularly to the field of MR TOFMS analyzers (MR – multiple-reflection, TOFMS – time-of-flight mass spectrometer), and can be used in medicine, biology, the oil and gas industry, metallurgy, power engineering, geochemistry, hydrology, and ecology. For the purpose of enhancing the resolution of an MR TOFMS, its RS (reflection system) is provided with a number of special features, the most important of which are that: (a) a COSS (corpuscular optical subsystem) of the analysis channel comprises one or more COSS assemblies, selected from types of bi-reflective components and comprising a pair of mirrors selected from a range of mono-zonal and bi-zonal mirrors, said assembly being designed to allow selection of the size of acute angles γ1 and γ2 between the directions of the ionic output flux from one CO mirror and the input into another CO mirror, within the limits of π/4<γ1≤0 and 0≤γ1<π/4; 0≤γ2<π/4 and - π/4< γ2≤0; (b) the COSS of the analysis channel comprises one or more deflecting and correcting COE (corpuscular optical element) designed to allow S/TOF-FIP (stepped time-of-flight focusing of an ion packet according to the energy scattering of the ions in the packet), together with a mono-zonal or bi-zonal CO mirror; (c) an ion source unit is provided, comprising an energy-filtering ion flux generating source, including a source type with a "compensated difference in ion flight path length".
