摘要：

Higher order interpolations in plasma simulations using particles have been studied in one dimension. Various schemes including quadratic and cubic splines and interpolation with Gaussian particles are tested when the Debye length is much smaller than the grid size. It is found that the effects of aliases and numerical instabilities can be neglected when the higher order schemes are employed in the simulation. It is suggested that the combination of higher order interpolations in the direction of magnetic field and linear interpolation in the cross section may be useful for three-dimensional simulations of magnetically confined plasmas for controlled fusion. © 1979.
