Miniature highly sensitive electron spectrometer for the analysis of corpuscular fluxes

Abstract

The work is devoted to the theoretical development of miniature highly sensitive electron spectrometer for the analysis of the composition of corpuscular flows in a wide range of measured particle energies. The mirror type axially symmetric energy analyzer in the spectrometer is constructed on the basis of an electrostatic octupole-cylindrical field and has a long-focal-length distance. The focusing properties of the scheme have been calculated, and the luminosity and resolving power of the device have been evaluated. As part of a set of equipment for spacecrafts, the proposed device will allow to determine the composition of charged particles in unsteady flows in interplanetary space. Also when designing the device there is a possibility to combine several methods of analysis (for example, with mass-spectrometric methods), which will successfully complement each other, which will provide high information content of joint analysis. This tendency is observed in the creation of space research complexes, which, as a rule, include several independent methods of analysis.
