摘要
A trajectory integrator is developed based on a particle's guiding center Hamiltonian.It is verified by a series of benchmarks,which are in good accordance with theoretical prediction.This integrator can be used as the guiding center trajectory integrator of a particle-in-cell simulation platform,such as the newly developed VirtEx.It can also be used as a stand-alone tool to investigate particle dynamics in a given background field.
