FORMATING DOUBLE LAYER MECHANISM BY ELECTRIC CHARGED PARTICLE STREAM IN PLASMA

In this paper, two-fluid equations have been solved after having considered magnetic field generated by charged particle stream. Finally, the distribution of electric field E_z(z,r) and its growth rate \gamma in plasma have been obtained. From the expression of E_z(z,r) it can be known that the double layer has been formed. With the increase of disturbance \gamma will be larger, and finally this will result in the interruption of electric current and occurrence of burst.
