Abstract

In the hydrodynamic model of plasma with relativistic electrons (REs), the dependence of the electron velocity on the radius within stationary cylindrical current structures is studied as applied to filaments in the plasma focus (PF). It is shown that electrons flowing in plasma around tangential discontinuities in stationary filaments do not reach relativistic velocities. At the same time, REs can be localized within tangential discontinuities, if megagauss magnetic fields are generated. In the case where the physical parameters are linearly distributed within a discontinuity, the relation between the tangential discontinuity width and the plasma density near the cylindrical filament axis is determined.
