Two-stage beam-plasma system as a source of multicharged ions

The possibility of generating multicharged ions in a two-stage beam-plasma system where regions of plasma generation and heating are spatially generated, is studied. Plasma with electron temperature of the order of 300-500 eV and current density of 2x1010 cm -3 is obtained using the 2 KeV electron beam with 1A/cm2 current density. Distributions of argon ions charge in such a system are given, the results obtained are compared with the data on other sources of multicharged ions. The conclusion is made that the above two-stage plasma-beam system can be alternative respective to systems with electron cyclotron resonance when creating sources of multicharged ions for accelerators
