A physical model of transport in an azimuthator channel with the sheath effect resulting from the interaction between the plasma and insulation wall is established in this paper. Particle in cell simulation is carried out by the model and results show that, besides the transport due to classical and Bohm diffusions, the sheath effect can significantly influences the transport in the *** a result, the ion density is larger than the electron density at the exit of azimuthator, and the non-neutral plasma jet is divergent, which is unfavorable for mass separation. Then, in order to improve performance of the azimuthator, a cathode is designed to emit electrons. Experiment results have demonstrated that the auxiliary cathode can obviously compensate the space charge in the plasma.

In a plasma accelerator with an anodic layer(PAAL),we discovered experimentally the effect of‘super-acceleration'of the bulk of the ions to energies W exceeding the energy equivalent to the discharge voltage V_(d).The E×B discharge was ignited in an environment of atomic argon and helium and molecular *** charged argon ions were accelerated most effectively in the case of the largest discharge currents and pressure P of the working *** ions with W〉eV_(d)(e being the electron charge)were only recorded at maximum *** nitrogen was not accelerated to energies W〉e V_(d).Anomalous acceleration is realized in the range of radial magnetic fields on the anode 2.8×10^(–2)≤B_(rA)≤4×10^(–2)*** was also found analytically that the cathode of the accelerator can receive anomalously accelerated *** this case,the value of the potential in the anodic layer becomes higher than the anode potential,and the anode current exceeds some critical *** modeling in terms of the developed theory showed qualitative agreement between modeling data and measurements.
