Shrnutí:Title screen
The features and regularities of plasma-immersion formation of high-intensity repetitively pulsed beams of aluminum ions, as well as their transportation and ballistic focusing in an accelerating system with a curvilinear extracting potential grid electrode under application of negative bias with high pulse repetition rate of f = 105 Hz are studied by numerical methods. It is shown that the amplitude and shape of the ion beam current pulse depend significantly on the dynamic conditions of space charge neutralization of the beam. In case of using of bias potential with high duty factor, e.g. conditions of limited time of vacuum-arc plasma preinjection, the process of transportation and ballistic focusing of the ion beam up to densities manifold exceeding the density of the preliminary injected plasma, it is possible to obtain conditions leading to the formation of a virtual anode. It is shown that secondary electrons can be one of the additional mechanisms of compensation of the beam space charge which results in the improvement of transportation of high-intensity beams of aluminum ions.
