• Experiments are conducted to study the effects of X-ray radiation and supra-thermal electrons produced by laser-produced plasma on the energy transport.Plasmas were produced by irradiating aluminum coated silicon targets (layeredtargets) with 1.06 pm Nd: glass Baser of 10" W/cm" power density. The nano-second time resolved X-ray spectra (1.5x2.2keV) were measured with thescintillator-photomultiplier array. The layer from which He-like tons arc origi-nated is limited to have a depth of 0.1 qm into the target, and the Si K. lineemitting region has a depth of about I 7vm. The duration of K. line signal is longerthan that of Al Xll line (Is2p 'P - Is" S) signal. The K. emission can be explainedby X-ray absorption in the target material.
