Abstract
The acceleration of a current-free plasma in a divergent magnetic nozzle with fully magnetically guided electrons is discussed. Ion momentum is gained from the electron thermal pressure, via the electrostatic self- eld. Except for very large magnetic elds, ion magnetization is weak and ion streamlines deviate from magnetic streamlines. As a consequence the local ambipolar condition does not hold, and local electric currents are formed. Azimuthal ion and electron currents are evaluated. The acceleration eciency is computed.
