The present paper the results of development of first experimental tests of a new ionized cluster beam (ICB) source. The novelty of ICB source lies in the fact that the crucible and ionization parts are spaced in one cylincrical shell but are not divided inan electric circuit. The ICB source adapts permanent mannets to increase the ionixation efficiency. The maximum obtained Cu+ ion current density I s1.5μA/㎠ 이었으며, 증착율이 초당 0.4Å일 때 이온화율은 3% 이었으며, 증착율이 초당 0.2Å일때는 이온화율이 6%이었다. 증착율이 초당 0.2Å이고, 가속전압이 4kV에서는 Cu+ 이온빔의 균일성이 95%이상이었다.
The present paper represents the results of development and first experimental tests of a new ionized cluster beam (ICB) source. The novelty of ICB source lies in the fact that the crucible and ionization parts are spaced in one cylindrical shell but are not divided in an electric circuit. The ICB source adapts permanent magnets to increase the ionization efficiency. The maximum obtained $Cu^+$ ion current denisity is $1.5{\mu}A/\textrm{cm}^2$, therewith the ionization rate amounts 3% under deposition rate is 0.2$\AA$/s and the acceleration voltage is 4 kV, the $Cu^+$ ion beam uniformity is better than 95%.
