Dynamics of plasma bunch in weakly inhomogeneous magnetic field

Summary form only given. The initially confined plasma bunch in vacuum in the absence of magnetic field unlimitedly expands and cools with time. It occurs that a certain configuration of external magnetic field allows the bunch to accelerate and compress as a whole. Using the exact solution of a system of two 3D Vlasov kinetic equations with a self-consistent electric field and external potential forces (Dorozhkian et al., 1998(2)), it is possible to predict the dynamics of a two-component plasma bunch in nonstationary weakly inhomogeneous magnetic field in the mirror configuration: B(r,t)=B/sub 0/(z,t)e/sub z/+B/sub r/(x/sup 2/+y/sup 2/,z,t)e/sub r/.
