Abstract: | The possibility of producing homogeneous plasma in a low-pressure discharge with the use of a hollow anode or hollow cathode
is analyzed. It is shown that, in contrast to the high-pressure discharge, where uniform ionization is needed to produce homogeneous
plasma, in the low-pressure discharge, nearly uniform radial distribution of the plasma parameters can be achieved under nonuniform
ionization conditions by increasing the ionization probability at the system periphery and reducing it near the system axis.
It is shown that the magnetic field can facilitate generation of the homogeneous plasma instead of interfering with it. |
