摘要
A new particle-moving algorithm for particle-in-cell simulation of plasma is developed based on the linear multistep method. The conventional and the new algorithms are investigated by numerical experiments, which are conducted in three typical fashions of the electron motions in electromagnetic fields, namely, cyclotron in homogeneous magnetic field, drift in E x B field, and motions in inhomogeneous magnetic field. The new algorithm not only improves the accuracy, but also relaxes the time step condition for the simulation, thus increasing the computation efficiency.
