1. The project.
AP09058188 Development of the electrostatic energy analyzer for the study of corpuscular flows in outer space.
2. Urgency.
The study of the dynamics of electron flows is of great interest for various problems arising in the construction of the theory of radiophysical devices, the formation and transportation of electron beams in plasma and vacuum, injection of electron beams into plasma in laboratory conditions and in space (active experiments), etc.
The solution of problems related to highly sensitive analysis (substances in microelectronics, biology, ecology, archeology, etc.; particle fluxes in interplanetary space in cosmic physics and geophysics, etc.) became possible thanks to the development and application of the so-called physical methods of analysis. Moreover, at present, of the physical methods, the most widespread are spectroscopic methods, of which a group of actively developing methods of corpuscular spectroscopy should be distinguished, including methods of electron spectroscopy. However, there is a wide range of unresolved problems in this area, which determines the need for detailed theoretical and practical research. For example, the problems of modern spectral analysis are being updated, which need to be solved under conditions of a sharp increase in the requirements for the sensitivity and resolution of the supporting equipment, the complication of the geometry of the experiment, the need to simultaneously study several parameters, accelerate the research process, etc.
Space exploration cannot be imagined without modern technology and technology. Every year, hundreds of satellites are launched into orbit to explore extraterrestrial space, which are equipped with advanced equipment that makes it possible to remotely study physical processes, their impact on the Earth, and register various space objects. Spectrometers, as the main instrument for space exploration, began to be used more than half a century ago. The main analyzing element of the spectrometer is the energy analyzer. In general, the modeling of energy analyzers for research in space is an urgent problem of science.
The creation of analytical instruments for working on mobile objects in space research, in addition to high analytical characteristics, additionally imposes on their design stringent requirements for weight, dimensions, mechanical strength, vibration and thermal effects, etc.
One of the serious problems in the development of systems for energy analysis of charged particles beams is the determination of the deflecting field and the calculation of the shape of the deflecting electrodes. The search and selection of electrode configurations of the device is dictated by the simplicity of its manufacture and the possibility of high-quality energy analysis due to the correction or compensation of electro-optical aberrations.
3. Purpose: the development of a new type efficient electrostatic energy analyzer for space research, having a small mass and sizes.

Achieved results.
The possibility of creating effective energy analyzers of corpuscular flows on multipole electrode systems is theoretically substantiated. The electrode system capable of creating electrostatic fields with focusing properties that can be used as effective energy analyzers of charged particle flows has been selected. The calculation and analysis of equipotential portraits of electrostatic octuplet-cylindrical fields to determine the electrode configuration of the mirror analyzer are carried out. The graphical visualization of equipotential portraits of electrostatic octupole-cylindrical fields with different weight contributions of a cylindrical field and a circular octupole is given. Trajectories of charged particles motion in the axially-symmetric octupole-cylindrical field constructed on the basis of a superposition of fields of a cylindrical mirror and a circular octupole are calculated by using an approximate-analytical method for calculating trajectories. The integro-differential equation of charged particle motion in the octupole-cylindrical field is determined.
Based on the results of research on the project theme 3 scientific publications were published in 2021, including 1 article in the journal recommended by CCESME MOS RK and included in the Scopus database, 2 reports in the materials of international conferences.
