Description
The anomalous effect discovered in the PAMELA experiment[1] and confirmed by subsequent cosmic ray experiments consists in a sharp increase of the fraction of galactic positrons over much of energy range 1.5 - 100 GeV, which contradicts theoretical predictions. To study this effect, a new experiment for detecting high-energy electrons and positrons using synchrotron radiation in the geomagnetic field was proposed[2].
In this work, we simulated the operation of a detector for different satellite orbits and orientations. The counting rate of the detector located in the polar orbits at an altitude of 400 km above the Earth's surface for positrons in the energy range 1 - 10 TeV has been estimated.
