- Аннотация: The main instruments for analyzing the processes occurring in cosmic plasma are energy and mass analyzers ofcharged particle beams. The analyzers’operation is based on the separation of charged particles according to theenergies of their motion or their masses in electric or magneticfields. Currently, the top-hat analyzer is consideredthe main instrument for obtaining information about the state of cosmic plasma. However, it has a number ofdisadvantages: a significant time cycle for registering angular dependences in a total solid angle of 4πsr and lowaccuracy of determining the polar angles, which are associated with the need to rotate the analyzer duringmeasurements. Over the past 20 years, plasma analyzers with a large viewing angle have been developed as analternative to the top-hat analyzer. The design of the analyzer proposed in this work is capable of measuring plasmacharacteristics in a solid angle of 2πsr in one act of data registration. The all-sky spectrometer of hot cosmicplasma consists of two stages: thefirst stage is a conical lens of an original design, which serves to transform anextremely wide entranceflow of particles into a narrow cone-shaped beam; the second hexapole-cylindrical stageplays the role of an energy analyzer of a narrow cone-shapedflow. The paper describes the calculations andmodeling of the proposed analyzer on the basis of original numerical and approximate analytical methods fordesigning systems of electron and ion optics. The main parameters of the device are calculated.
