Areas such as cross-field transport in magnetic confinement configurations such as the tokamak are becoming extremely relevant in providing an under standing of particle transport to the tokamak plasma boundary.
In the present case, the azimuthal dependence (cgs\c 0) must be retained, since the unperturbed momentum distribution function includes the cross-field particle drift.
In these codes, anomalous cross-field plasma transport is usually described by adding diffusive terms into the particle and energy balance equations.
This means that a cross-field electric field is produced by the dynamo effect of the cross-field particle drift or acceleration due to electrostatic waves.
This leads to anomalous cross-field electron thermal transport.
We consider both modified two-stream and dust-acoustic instabilities that are driven by an ion cross-field drift and that occur for waves propagating obliquely to the magnetic field.
From the momentum-space diffusion equation, it can be seen that there is infinitesimally anisotropic momentum-space diffusion around the magnetic field and a resulting infinitesimal cross-field particle acceleration or transport.
In order to come close to these requirements, impurity injection into the edge plasma in the cross-field direction can be used.
