Abstract—
The influence of metal grids on the characteristics of particles extracted from a plasma was investigated in the course of development of the laser-plasma ion source for heavy-ion injectors. Plasma was produced by irradiating carbon and tungsten targets by СО2 laser pulses with a flux density of ~1011 W/cm2. The influence of grids was estimated by measuring the signals from a detector−analyzer of ion energy spectra, the total ion current, and the ion-beam emittance behind the extraction system. A significant effect of the geometrical parameters of the grid and the ion mass number on the ion-beam characteristics was observed. The results we obtained can be qualitatively explained by the sputtering of the grid material by a high-energy particle “head” of the ion beam and by the subsequent effect of the produced atomic-gas “cloud” on the ion-beam transmission.
