Time-of-flight spectra of C, Fe, and Si ions produced with the use of a KrF excimer laser were analyzed. Responses of Faraday cups collecting the ions were analyzed with the use of a detector signal function, which was derived from shifted Maxwell-Boltzmann velocity distribution. The deconvolution method allowed to estimate parameters of partial currents of all the ionized species constituting the expanding plasma plume, such as the ion temperature and the center-of-mass velocities. Furthermore, the linear charge-state dependence of the center-of-mass velocity has revealed the contribution of hydrodynamic and electrostatic forces to the expansion velocity of the plasma.
