Abstract :

The technology of plasma-optical mass separation (PO�?S) implies, for a particular separator design, a certain maximum energy of ions in the multicomponent flux. The source of the ion beam in PO�?S is represented by the plasma accelerator (РА), the ion flux from which must pass through a device called the azimuthator, a magnetic barrier (�?�?). Within it, the ions of different masses gain corresponding azimuthal velocities (energies), in accordance with which each of them does focus on its respective receiver in the separating space of POMS representing the Hughes-Rozhansky energy analyzer. Publications report on the observation of the PA operation modes where a significant number (up to 80%) of ions are generated with energies exceeding the value determined by discharge voltage Ud (Fig. 1; the values averaged over 20 ms). For POMS this is inacceptable. This paper discusses the causes for the generation of anomalous ions, both in a macroscopic potential jump in anode layer and as a result of acceleration in the interaction with plasma oscillations. An important factor for any mass separator is its output. It has been found experimentally that ion losses in POMS occur, as was to be expected, when they pass through MB. For the non-monoenergetic ion flux, it is determined theoretically that there exists an optimum initial (at the MB input) density n0, at which the current at the MB output reaches a maximum value and the range of initial densities where the ion losses are relatively small (Fig. 2).
