Abstract

It is shown that relativistic electron current can propagate across the magnetic field B0 over a distance d much larger than the electron gyroradius, r0 ≃ mevzc/(eB0) ≪ d. This current is driven by the Hall electric field, which is generated on a spatial scale equal to the magnetic Debye radius rB = B0/(4πene) and causes the electrons to drift in crossed electric and magnetic fields. For a plane equilibrium current configuration, analytic profiles of the electron velocity and electron density are calculated and the electric and magnetic fields are determined. The results obtained are used to explain electron leakages in magnetically insulated transmission lines filled with a plasma expanding from the electrodes. Equations describing an equilibrium configuration of the ions and electrons that drift simultaneously across a strong magnetic field are derived.
