—This article describes the construction, principles of operating, and characteristics of the TOTEM- electron spectrometer developed for the Strannik complex of scientific instruments for the Resonance-MKA space project. In the article, analytical characteristics are presented of the qualification model of the instrument, which fully corresponds to the flight unit, and the procedure for functional tests of the instrument is described. The article also describes the structure and principles of functioning of the hardware and software laboratory facility developed for ground calibrations and tests of such a type of instruments. The design of the TOTEM-E instrument offers a new approach to measuring particle fluxes, which allows the accuracy and speed of measurements to be increased. A feature of the proposed scheme is the possibility of simultaneous measurement of electron fluxes in a plane section in the velocity space in the energy range from E0 to 6.5 × E0, where E0 is the minimum particle energy recorded by the instrument. This is achieved by using two conical electrostatic mirrors that take electrons from a flat 360° flow section for subsequent energy analysis and using a coordinate-sensitive detector for simultaneous particle registration.
