- Abstract
- Nonmonotonic distribution of an ion current density on radius was observed in point source of In and Sn. Reduction of a current density in the center of a beam is connected with generation charged nanoparticles with the sizes of 2-20 nm, and these nanoparticles extend along an axis of system. The observable low level of a current modulation is possible in the event that the size of area of ion emission considerably surpasses the size of area of nanoparticles. The ion beam with initial current density of ~106 A/cm2 is extracted from the liquid emitter in diameter of 100 nm.
