Abstract

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/.
