The paper presents numerically calculated model of the new electrostatic energy analyzer based on a bounded conical field, separating and focusing a flow of charged particles, having velocity parallel or nearly parallel to the axis of symmetry of the analyzer. The calculations show second order focusing with very large acceptance aperture, what is important for obtaining accurate data of intensity, energy characteristics, main direction of space particle flows, which are characterized by very low density. These data are important for monitoring and forecasting abnormal electromagnetic events over the Earth and near- Earth space which can effect on normal operation and even on the safety of the crew of space station. A combination of high energy resolution with large aperture, simple compact design and control and remote fine tuning makes the instrument very promising for space technologies.
