Origin of leptons in near earth orbit
It is shown that the ratio of the e + over e − flux below the geomagnetic cutoff reported recently by the AMS experiment is due to the geomagnetic East-West effect. New measurements of particle fluxes close to earth have been performed recently by the AMS experiment, providing a body of highly accurate new data on particle populations in the close terrestrial environment, which open new prospec...
متن کاملSecondary electrons and positrons in near earth orbit
The secondary e + and e − populations in near earth's orbit have been calculated by simulation. The results are in very good agreement with the recent AMS measurements. The e + over e − flux ratio for particles below the geomagnetic cutoff appears to be due to the geomagnetic East-West effect. The study of particle populations in the earth environment has been a field of intense research activi...
متن کاملNear Minimum Fuel Maneuvers for Multi Spacecraft Interferometric Imaging in Near Earth Orbit
In this article a methodology to obtain near-minimum fuel maneuvers for space-based interferometric imaging systems located in near-earth orbits, subject to the Clohessy-Wiltshire equations, is proposed. The methodology consists of a hierarchical controller consisting of higher level Non Linear Programming problem and a lower level Linear Quadratic Regulator. The solutions are obtained with the...
متن کاملThe production of proton and lepton fluxes in near Earth orbit
Substantial fluxes of protons and leptons with energies below the geomagnetic cutoff have been measured by the AMS experiment at altitudes of 370-390 Km, in the latitude interval ±51.7. The production mechanisms of the observed trapped fluxes are investigated in detail by means of the FLUKA Monte Carlo simulation code. All known processes involved in the interaction of the cosmic protons with t...
متن کاملOrigin of the high energy proton component below the geomagnetic cutoff in near earth orbit
The high flux proton component observed by AMS below the geomagnetic cutoff can be well accounted for by assuming these particles to be secondaries originating from the interaction of cosmic ray protons with the atmosphere. Simulation results are reported. The existence of a high flux proton component below the earth geomagnetic cutoff (GC), was reported recently by the AMS collaboration [1]. T...
