On Projective Connection of Optically Conjugate Points of Static Mass Analyzers
Autor: V. D. Sachenko
Publikováno v: Journal of Analytical Chemistry. 75:1825-1831
The Barber rule, known in the theory of sector static mass analyzers and connecting geometrically the axial point of an object and its electron-optical image (Gaussian points) in the case of a uniform field of a magnetic sector with a normal incidenc

Optimization of Vertical Acceptance of the Static Mass Analyzer
Autor: A. S. Antonov, A. S. Berdnikov, L. N. Gall, V. D. Sachenko
Publikováno v: Journal of Analytical Chemistry. 75:1660-1664
Axial aberration of the ion-optical system of a static mass analyzer is one of the factors limiting the transmittance and sensitivity of the device because of a need in significantly decreasing the vertical component of the ion beam emittance to get

An Ion-Optical Circuit of a Small-Sized Mass-Spectrometer for the Isotope Analysis of Hydrogen–Helium Mixtures
Autor: A. S. Berdnikov, N. R. Gall, V. D. Sachenko, A. S. Antonov, E. M. Yakushev, L. N. Gall, L. M. Nazarenko
Publikováno v: Journal of Analytical Chemistry. 75:1693-1699
We discuss an ion-optical system (IOS) of a mass spectrometer designed for isotopic measurements of light gases, containing a magnetic prism with plane-parallel pole tips and two sector-wise, cylindrical-capacitor identical in geometry, symmetrically

Practical realization and design of three-cascade prism mass analyzer for isotopic analysis of H-He mixtures using MS-platform technology
Autor: I A Gromov, L N Gall, V D Sachenko, N R Gall, Sh U Rajabov
Publikováno v: Journal of Physics: Conference Series. 2388:012020
The paper presents the construction of a mass analyzer for the analysis of hydrogen-helium mixtures based on a magnetic prism using a three-stage circuit that includes two cylindrical capacitors. The choice of an ion-optical scheme that provides a hi

Controlling the Resolution of Static Mass Spectrometers Using Intermediate Slit Diaphragms
Autor: V. D. Sachenko, A. S. Antonov, L. N. Gall, A. S. Berdnikov
Publikováno v: Journal of Analytical Chemistry. 74:1405-1411
The paper shows how to increase effectively the resolving power and transmission of a static mass spectrometer (i.e., to get an optimal compromise between these two parameters) using the properly positioned intermediate slit diaphragms in order to en

Optimized electron–optical system of a static mass-spectrometer for simultaneous isotopic and chemical analysis
Autor: N. R. Gall, L. N. Gall, S. V. Masyukevich, V. D. Sachenko
Publikováno v: Technical Physics. 61:114-118
A new approach to control the linear dimensions of analytical electrophysical systems is suggested. This approach uses the lens properties of electron–optical elements with a curvilinear axis. It is shown that such an approach can be effectively ap
