Software for Numerical Calculations of Particle Trajectories in the Earth’s Magnetosphere and Its Use in Processing PAMELA Experimental Data

A software package is developed for numerical calculations of particle trajectories in the Earth’s magnetosphere, and are given examples of its use in processing PAMELA experiment data. The particle-in-cell technique is applied according to the Buneman–Boris scheme. The approach is compared to other means of calculation often used to model the motion of charged particles in electromagnetic fields. The software package is tested by reproducing known effects of cosmic ray physics in the magnetosphere.
