Abstract:
An implicit, electromagnetic particle (kinetic) simulation method is presented that can deal with multi-dimensional, inhomogeneous and finite beta plasmas in large space and time scales. To include the diamagnetic effects in strongly magnetized (omega_ ce geq omega_ pe) and inhomogeneous, kinetic plasmas of the large scales, full-implicit "directly-coupled field-particle equations" are derived by using the backward time-decentered scheme and the guiding center approximation with the magnetic drifts about the electron perpendicular motion. This algorithm has been implemented for studies of inhomogeneous and magnetized plasmas of three-dimensions. The basic algorithm of the code is described and several physics applications are shown for the Alfven-ion-cyclotron instability and kink instability of the peaked density ion beam.
