The principles of designing the flight quadrupole mass spectrometers based on thin-wall hyperbolic electrode systems are considered. The aim of the work is to develop the principles of designing thin-walled electrode systems of quadrupole mass analyzers. The design of a quadrupole electrode system is developed, all four electrodes of which have a hyperbolic profile, limited on X and Y axes at a certain level. The technology to manufacture thin-walled electrode systems in the form of monoblock was created. By numerical simulation of monoblock electrode system, the quality of the electric field in it is estimated. Mechanical and thermal tests of monoblock electrode system were carried out. The constructions of flight hyperboloid mass-spectrometers (quadrupole mass filter and monopole mass analyzer) are proposed in which an extended electrode system is assembled from short identical monoblock sections. The sectional design of electrode system makes it possible to improve the quality of electric field in the working volume of mass analyzer.
Key words: quadrupole mass filter, monopole mass analyzer, thin-walled hyperbolic electrode, electrolytic coating, sectional electrode system.
