Study of the energy spectra of multiply charged Ti ions from a laser plasma

Experimental data are presented concerning the generation and investigation of multiply charged Ti ions from the plasma produced by the second harmonic radiation of a neodymium laser (with an energy under 14 J and a pulse duration of 2.5 ns). A group of ions with multiplicities ranging from +16 to +20 was recorded with an electrostatic energy mass analyser and a collector was employed to measure the ion current of this group, which was found to be equal to {approx}1 mA cm{sup -2} for an ion pulse duration of {approx}0.8 {mu}s.
