Objetivo Charge exchange pumping is an interesting - and until now very little investigated - alternative to existing schemes for generating population inversion and for pumping X-ray and XUV lasers. As a resonance process resulting in a highly selective level population with comparatively high values of cross-sections for collisions of highly charged ions with neutral atoms and ions (up to 10-14 cm2), it is able to provide high inversion and high gain coefficient. However, this scheme calls for a high flux of energetic ions of high-charge states in the presence of a suitable target consisting of cold plasma or neutral atoms. Energetic ion beams which can be produced by conventional accelerators have too low a flux of ions to achieve sufficient gain.High-charge state ion beams have long been observed in the final collapsed state of high-current discharges. The underlying common feature of such discharges is an axisymmetrical, highly dynamical compression of a current carrying plasma driven by the transient self-magnetic field. The ion beams are produced either as a result of the intrinsic geometry of the discharge during the plasma compression stage, or during the evolution of the m=0 type instability in the pinch stage within a dense magnetized plasma. The energetic, high-charge state ion beams produced in high-current discharges fulfill the requirement for high velocity and high fluxes. The generation of these beams in high-current discharges and their interaction with specially designed neutral or ionized targets will be studied. These plasma configurations are excellent test beds for the investigation of the charge exchange scheme based upon ion-neutral and ion-ion collisions.
