Some features of the vacuum arc plasma motion in a curvilinear magnetic field

The spatial distribution of the stationary vacuum arc plasma flows in a curvilinear magnetic field with a strength that satisfied to an unmagnetized ions are described. It is shown, that except for the basic flow propagation along the curvilinear magnetic field B, there are secondary plasma flows: radial, with a speed component in R-direction, and drift flow, propagated in an B x R direction (R is a radius-vector of a magnetic line of force). The dynamics of redistribution of plasma substance between these flows was monitored under a changing of electrical potential applied to the walls of the plasma guide.
