X-Ray spectral diagnostics of plasma, produced on the surface of solid targets by two successive nanoand picosecond pulses following one another with an interval of 1.2 ns, was performed with high time resolution (down to 2 ps) and high spectral resolution (up to 5X 103). The heating and the increase in the density of the preplasma, produced by the nanosecond pulse as a result of the action of a short (1-ps) intense pulse, was observed. The plasma parameters were determined at different stages of heating. © 1995 American Institute of Physics.
