| Research Abstract |
We have developed a specially constructed hollow cathode in which the primary electrons are sufficiently trapped. The new cathode makes it possible to produce superdense glow discharge whose current density is in the range up to 10 A/cm^2. The hollow cathode effect occurs independently of the cathode cavity size. We obtained the superdense mode even if the diameter of hollow cylinder cathode reduced to 0.23 cm. A more compact and intense ion source can be realized by using this discharge mode instead of conventional one.
In this study, we discuss the characteristics of superdense hollow cathode glow discharge and try to construct a compact ion source and a multi-ion source assembling seven compact ion sources. In the compact ion source we extracted ion beam of 25 mA/cm^2 when the discharge current is 0.1 A. The fluctuation of ion energies is 20 eV (FWHM). In the multi-ion source the spatial distribution of density and component ratio is easily controlled.
